Hi all,

Unfortunately very poor conditions this afternoon with extensive cloud forcing me to an early(daylight) capture between gaps in the clouds before being clouded out. Mars is now at 8h.

The Vallis Marineris complex is central. I was surprised how bright the SPC was today. In my opinion the albedo features seem rather subdued, although no indication of any major activity as yet.

Best regards,

Hi Guys AR2597 grew nicely as it approached the limb on the 28th of September, which was the last time I saw it. The solar disc appeared almost blank on the 2nd of October, except for a group of spots without penumbra, this group was eventually given the identf of AR2598.

 


 

New spot AR2599 was a welcome sight on the 3rd of October. It was also imaged on the 4th and again on the 5th but in lesser seeing. No clear skies since.

STUDY PREDICTS NEXT GLOBAL DUST STORM ON MARS

Global dust storms on Mars could soon become more predictable -- which would be a boon for future astronauts there -- if the next one follows a pattern suggested by those in the past.

 

A published prediction, based on this pattern, points to Mars experiencing a global dust storm in the next few months. "Mars will reach the midpoint of its current dust storm season on October 29th of this year. Based on the historical pattern we found, we believe it is very likely that a global dust storm will begin within a few weeks or months of this date," James Shirley, a planetary scientist at NASA's Jet Propulsion Laboratory, Pasadena, California.

 

Local dust storms occur frequently on Mars. These localized storms occasionally grow or coalesce to form regional systems, particularly during the southern spring and summer, when Mars is closest to the sun. On rare occasions, regional storms produce a dust haze that encircles the planet and obscures surface features beneath. A few of these events may become truly global storms, such as one in 1971 that greeted the first spacecraft to orbit Mars, NASA's Mariner 9. Discerning a predictable pattern for which Martian years will have planet-encircling or global storms has been a challenge.

 

The most recent Martian global dust storm occurred in 2007, significantly diminishing solar power available to two NASA Mars rovers then active halfway around the planet from each other -- Spirit and Opportunity.

 

"The global dust storm in 2007 was the first major threat to the rovers since landing," said JPL's John Callas, project manager for Spirit and Opportunity. "We had to take special measures to enable their survival for several weeks with little sunlight to keep them powered. Each rover powered up only a few minutes each day, enough to warm them up, then shut down to the next day without even communicating with Earth. For many days during the worst of the storm, the rovers were completely on their own."

 

Dust storms also will present challenges for astronauts on the Red Planet. Although the force of the wind on Mars is not as strong as portrayed in an early scene in the movie "The Martian," dust lofted during storms could affect electronics and health, as well as the availability of solar energy.

 

The Red Planet has been observed shrouded by planet-encircling dust nine times since 1924, with the five most recent planetary storms detected in 1977, 1982, 1994, 2001 and 2007. The actual number of such events is no doubt higher. In some of the years when no orbiter was observing Mars up close, Mars was poorly positioned for Earth-based telescopic detection of dust storms during the Martian season when global storms are most likely.

 

Shirley's 2015 paper in the journal Icarus reported finding a pattern in the occurrence of global dust storms when he factored in a variable linked to the orbital motion of Mars. Other planets have an effect on the momentum of Mars as it orbits the solar system's center of gravity. This effect on momentum varies with a cycle time of about 2.2 years, which is longer than the time it takes Mars to complete each orbit: about 1.9 years. The relationship between these two cycles changes constantly. Shirley found that global dust storms tend to occur when the momentum is increasing during the first part of the dust storm season. None of the global dust storms in the historic record occurred in years when the momentum was decreasing during the first part of the dust storm season.

 

The paper noted that conditions in the current Mars dust-storm season are very similar to those for a number of years when global storms occurred in the past. Observations of the Martian atmosphere over the next few months will test whether the forecast is correct.

 

Researchers at Malin Space Science Systems, in San Diego, post Mars weather reports each week based on observations using the Mars Color Imager camera on NASA's Mars Reconnaissance Orbiter. A series of local southern-hemisphere storms in late August grew into a major regional dust storm in early September, but subsided by mid-month without becoming global. Researchers will be closely watching to see what happens with the next regional storm.

Hi all,

Some commitments meant I was only able to capture a bit later on the 4th. I was pleasantly surprised that the seeing was not that bad.

The scope was swung across the pier, and a rather severe limb effect was noted, which I have not processed out in the decomposed channel images. I am wary of the possible contrast/limb effect just below the SPC, and am not sure how accurate this is in reality.

 

Out of interest, I have been testing live streaming from my observatory, and may do further testing, including live streaming of Mars, later today(6 October) from about 15.00UT, weather permitting. If you want to have a look, please go to my Youtube channel(I will set it to public) at between 15.00 and 15.15UT.  You should pick it up if you search for gClyde Fh. Seeing has not been great, and we have been having late afternoon cloud the last few days, so I cannot guarantee a decent view. However, it is Mars, and it will be live!

In the center are the regions of Tharsis, Arcadia, Amazonis. In south is the Sirenum Mare. The visibility is very low in the image, which does not allow the observation of details.

This was possible in a new night with low clouds, after almost a month of bad weather, but seeing conditions were poor-average.

Dear Dr.Minami, All,

 


 

 Attached here is an image taken with a little VMC webcam on board Mars Express/ESA on this 28 September 2016, a south polar view of the full noon Mars centered on the meridian. I fondly remember the views of the same Martian season in my first apparition of Mars observation in 1971 (please see attached my drawings).

 


 

According to Richard McKim's "Telescopic Martian Dust Storms: A Narative and Catalogue", p86, a large regional dust storm began on the night of 10/11 July 1971 at =213KLs over the Hellas Basin, with the activity last detected on 22 JulyGThis seems to be comparable to the latest regional dust storm activity observed by CMO imagers which began on 03 September 2016 at =216KLs at the eastern end of Deucalionis Regio/Pandorae Fretum, entering its final "decay phase" around ten sols after the start (according to the comment in the MRO MARCI Weather Reports for the Week of 12-18 September 2016). In 1971, the historic greatest global dust storm(which have welcomed Mariner 9 probe) was entrained on 22 September at =260KLs. ...We can expect an exciting event within a couple of coming months!?

Dear Masatsugu,

   We have those images here also in the planetary patrol plate collection. On October 15, we are having a celebration--100 years since Percival Lowell's death--in the Putnam collection, and then a week later, the Antique Telescope Society will be visiting Mars Hill. 

 I am giving a talk in the rotunda of the Slipher building (built 1916), "Percival Lowell's last year."

Hi Richard,

Thanks for copying me on the 1888-1890 images by
Pickering. I took the liberty of enhancing them by removing the prominent noise and then on two of them erasing the bright field of view around the disks. See attachment. One hundred years later I imaged Mars for Lowell Observatory on 10 nights using a 24" f/75 Cassegrain scope in an observatory on Mauna Kea in 1988. I'll try to make a composite of some of my images.

 

Good seeing,

Received: 1 October 2016 at 00:46 JST

 

Many thanks for these interesting items.

Remarkably good prints of the 1888 Mars photos by Pickering were published by him more or less at the time (if I recall correctly), and then again years later in the series of (44 in all) popular Mars reports he published in the now defunct US journal Popular Astronomy. I suspect the reproductions in the latter were slightly retouched. The latter journal is certainly online, and the reports dealt with the work of a select group of amateur observers up to 1928. The last detailed reports published were for the 1926 apparition. Years later I looked for
Pickering's original records of his drawings of Mars, but the main collections at Tulhane University archives in the USA did not have any of his Mars work, just notebooks dealing with his lunar observations, made from Mandeville, Jamaica. The suspicion is that an earlier archivist or director had discarded his Mars work, thinking it too controversial. But if anyone knows differently.......

It would be of much interest to see direct scans of the originals, or perhaps some stacked multiple images where available.

With regards

Funny you should mention this:

 

Hereby the Circle of Mars:

 

1. 1888 – William Pickering takes the first pic of Mars from the Alvyn Clark 13 inch

2. 1894 – He shows the pics to Percival Lowell who asks him to build an observatory for the specific use to study Mars (and looking for canals and life), Lowell Observatory Flagstaff Arizona

3. 1939: - Earl Slipher from Lowell Observatory takes a Mars expedition to the Lamont Hussey Observatory in Bloemfontein to take the best photos yet of Mars, including the first colour photo ever.  Got help from Boyden engineer Eric Burton to put up the camera.

4. 1964 - NASA uses Slipherfs Maps of Mars for the first flyby (Mariner 4) to take the first Pics of the surface, and no canals!  From here follows the rest of the Mars expeditions by NASA.

5. 2000 – Amateur Astronomers discovers the camera Slipher used for the first colour photograph of Mars behind the Elephant camp in the zoo.

6. 2014 – Slipherfs exhibit opens at the Boyden Museum.

7. 20?? – 13 inch Alvan Clark exhibit opens with a (better then Hubble) Mars photo taken from the 13 inch by Clyde Foster.

 

Howfs That!

Hi Guys Here is a selection of images from 13th to the 24th of September, a couple in good seeing and the rest in average seeing. I noticed some small flares in AR 2593 and AR2596 at 09:49ut on the 23th.

 

The Ha images are half the resolution of the white light images, that is with the 7 inch AP reduced to 3.5 inches by the addition of the 90mm Coronado etalon.

 

The sprawling spot group AR2593 showed no penumbra at all on the 24th. Let me have a go at classifying it, as a complete beginner, to me it seems to fit the Bxo Mackintosh classification. Now for AR2596, lets try Cso for that one. How did I do?

Hi Clyde.
It looks like the dust clouds West of Hellas have dissipated, but
Hellas shows dust inside and in lobes in the Southwest and Northeast corners. It's hard to tell if airborne dust or recently deposited fine dust on the ground.

HI all,

My Mars capture from yesterday afternoon.

The main(Colour) image is a little bit less processed than normal, as I have tried to highlight some structure extending over the north western edge of the Hellas basin. The separate channel images have been generated from a more processed image. The bright north western side of Hellas can be seen quite nicely in the IR and R images. Hoping for reasonable conditions over the next few days.

Hi, Jim.

Thanks as always for your comments.  My initial thoughts regarding the large, broad band across the upper section of the planet was that it may be "fallout" (settled/settling dust) from the recent Hellas storm.

I haven't seen many "after the storm" images over the last few days, so I am hoping that the weather settles here and I can monitor this region and also Hellas over the next week or so.

Best regards,

Hi Clyde

Your picture shows a massive dust storm to the West of Hellas. Now the question is are the dust clouds produced by South to North winds from the edge of the subliming CO2 ice or are they produced by East to West prevailing winds in the current season? Possibly both!

There is a lot of imagery to interpret.

Thanks.

With the good seeing on the 30th August and 11th September, I pushed the f ratio to a silly length, as on screen it just gworked,h I doesnft actually resolves more, but itfs interesting to push the equipment beyond the norm. Less noise from less screen enlargement may be a plus. The images reminds me of a bowl of sweet-corn with raisins ! Not that I take raisins with sweet-corn, but hey donft knock it till,,,,,,,,,,,.

The excellent on the 11th encouraged the imaging of vast fields of convection cells.

Hi all,

A cold front has come through and cloud only cleared in time for this capture. However, seeing was very poor, making for difficult processing.

Despite that, it appears to me that the cloud in Argyre has dissipated somewhat, whilst the two clouds over Niliacus Lacus  may have consolidated and may even have increased in intensity. Hopefully I will be able to monitor over the next few days, although cloud and rain is forecast for the weekend.

The Argyre region appears to remain active with the red channel indicating substantial dust.

In your latest image, Clyde, it appears to me that there may be three separate lumps of brightness within Argyre. This peculiarity is consistent with dust cores. On the other hand, in the red image Argyre is not brighter than eastern Chryse, and like eastern Chryse it is aligned in the second brightness ring of diffraction effects. I'm afraid that, just by viewing the
image, I have to consider it suggestive of dust but, by itself, insufficient evidence to be sure. This type of reasoning is often applicable with suggestions of dust storms, and it's why we always want more images!

 

Keep up the good work.

Thanks, Jim.

I've seen a number of images over the last week indicating the expansion (and possible dissipation?) of the Hellas dust storm to both the east and west, so was expecting (hoping! )to see at least some indication of dust possibly on the south preceding part of the planet, which may actually be the case. However I agree that Argyre looks bright enough in the red to indictate that there may be additional dust storm activity taking place.

 Comments welcome. Regards,

Hi Clyde,

Your previous image and this one shows Argyre to elongated and much brighter than usual. I'm thinking it's dust clouds. If you can keep imaging, then we will know for sure. Thanks,

Hi all,

Resorting to almost daylight conditions to try and get the best seeing conditions, but processing is becoming more difficult. Argyre region remains bright.

Hi Guys This set concludes August images. The star of the show for me was the appearance of AR2584 on the 31st, captured here in a bit of descent seeing.

 

For the record, the white light images are off an AP178 T with an Intes wedge at f22, on the 3.5Mu pixels of the ZWO ASI 120 MM-S

 Ha images are off a 90mm solarmax set, single stack atop the 178.

Dear Dr.Minami,
Attached here is my latest Mars image with my new ASI 290MC camera, managed to capture through a hole in the heavy clouds. Seeing was better go out drinking one, but the image suggests the extention of the dust along southern mid to high latitude zone.

   Clear Skies with Good Seeing!

Hi all,

An early twilight capture of Mars with Argyre region appearing bright, although this appears to extend across quite a large area. Possibly my first capture of the activity that initiated in Hellas and has extended east and west? The fine line of cloud near the SPC is persisting.

I have not tried to process out the preceding limb arc.

 -Franklin-Adams refractor ASSA Johannesburg, Johannesburg Observatory

Hi all,

Something a bit different and rather special for me.

With my recent appointment as Director of Shallow Sky Section of the ASSA, one of the rather pleasant spin-offs has been an increase in interaction with some of the great South African Astronomical institutions.

Yesterday I was invited by Jerome Jooste of ASSA Johannesburg to visit the Johannesburg Observatory (previously known as the Transvaal, Union and Republic Observatory) to test my imaging on the historical  6h Franklin-Adams refractor. I am trying to dig out more information on the telescope, but believe it dates back to the 1880fs, and is an f18 Cooke triplet. The Observatory also still houses the 26,5h Innes refractor which is currently being used for double star work, but which has been used for planetary work in the past.

*

I had a great session taking some lunar images and then managed to capture a couple of Mars images as the sky darkened.  Seeing for the Mars session was deteriorating(although also not terribly bad) with intermittent cloud moving in.

The colour correction on the scope looked excellent and it certainly was a privilege for me to be able to image through this scope.

Attached is the Mars capture(south is top), which, given that it was a 6h scope, the seeing, and that Mars is now below 10h, I was fairly happy with. I used a 2x Barlow.

 


 

I unfortunately did not have the fittings to attach an electronic focuser, so resorted to manual- not ideal, but do-able.

Regarding the recent dust storm activity, the south following limb(upper right) appears suspiciously bright.

I have attached a few photos from the session- a memorable experience.

Best regards, and I will be back in my own observatory this evening, weather permitting,
