Hi all,

Mars earlier this morning. Conditions were very poor, but I wanted to check what was happening with the latest Solis Lacus storm. It appears to still be active but may be reducing rather than increasing. Other observations required to confirm.

Mars image set from yesterday evening. Provided conditions are reasonable this evening, this will be one of two sets of images straddling Marsf closest approach.

S Sabeaus/S Meridiani showing some, albeit slow, return towards normality, but the Margarifiter extension remains affected.

Hi all,

Mars at opposition. Things could have been so different, with the high expectations prior to the dust storm, but it has nonetheless been fascinating watching as things unfolded. Even the recent Hubble image seemed somewhat subdued. My respect to those fellow imagers that have conscientiously followed the amazing planetary trilogy over these last months. Even with my unplanned and enforced layoff for a month, I feel like I have run a few marathons. And there's still plenty to do in the coming months......

Best regards, Clyde

Hi all,

I was pretty much set up for an all-nighter last night, having seen a recent general trend of improved seeing from about 21.00 local time through to midnight. Unfortunately conditions started as very poor at about 21.00 and I only got very slight improvement over the next few hours. I stayed at it until I was able to confirm the reduction of the small storm near Solis Lacus rather than an increase in intensity, and then called it a night. Although it could still be seen, it looked greatly reduced in intensity.

All in all, rather frustrating, but will try again tonight and hopefully enjoy the adjacent lunar eclipse.

At least I got a reasonable IR capture and the limb brightening  was again detected, although limited in B.

Best regards, Clyde

Hi, all

The full image set from yesterday evening.

Other than the small outbreak in the Solis Lacus region, a few other things I note:

a) The limb brightening continues and appears to also have a G component.

b) M Acidalium is showing as very dark

c) The NPH(I hope that is accurate), in the last few days seems to have significantly reduced in brightness, and it appears that some structure may be detected as a dark area in the R image

Hi all,

I captured a fair bit of data last night, but with Nick Haigh reporting an outbreak in Daedalia, I did a very quick process of my last capture of the evening and it indeed shows the storm in the Solis Lacus/Daedalia region at upper right. This region has been very active throughout the duration of the main storm.

Hi all,

Mars 3 days before opposition. I had suspected some limb softening yesterday, but today there appears to be a significant limb brightening around the planet, most noticeable in the B image. I donft recall anything similar in 2016- possibly due to the dust ?

S Meridiani starting to be a bit more obvious in visual wavelengths.

I will try and do a bit more work on it, but I did a quick comparison of the IRfs from yesterday and today, specifically looking at the bright regions just south of Meridiani and Margaritifer. My initial conclusion was that there was limited significant changes- possibly pointing to the bright regions being settled on the surface? Comments welcome.

Subtle light cloud can be seen extending off the NP region in the B image

On a  lighter note, it almost appears as if the northern section of Margaritifer has detached and moved north during the storm.

Visually Mars appears no different somewhat reminiscent of images of Titan. Vaguely make out the SPC and some dark Southern Markings.  Otherwise, here is an IR image from this morning.

Dears,

No miracle here, Jupiter was very low (between 18 and 13) at acquisition. What surprised me is that  founs the 13 image is the best (probably because of the narrow infrared bandwidth for this methane absorption band image).
Oval BA is setting preceded by 3 white features, 3 white ovals visible in the SSTB, the wavy north edge of the
NEB is visible, and a curious shape of a feston in EZ.

Dear Masatsugu and Masami,

 

Attached are some images  of Mars taken on July 18th and 20th .  

 Although I understand the dust storms have now subsided, there still appears to be a lot of dust in Marfs atmosphere. 

 Observing visually I had a really tough time making out any of the darker albedo features.  Even though Syrtis Major was in good position on these two mornings it only showed as some slight mottling through the eyepiece. 

 The bright poles and Hellas were visible but that was about the only things that were clearly showing through the eyepiece. 

  I was glad that on the morning of the 20th I had one my friends, who is a very experienced visual observer, join me and confirm my visual observations.

 

Best wishes,

The SPC remains complex in IR and R. Argyre at upper centre and Valles Marineris stretches across the centre of the image.

Out of interest, almost the whole session last night was done by remote operation of the observatory from my study. It was all a bit more comfortable than normal!

Hi all, some excellent seeing last night despite elevation of 18 to 16 only. While the storms are clearly over now, the constrast in visible wavelengths remains weak, and visually, I did not see any difference from the past weeks. Only the new dark Daedalia/Araxas marking could be glimpsed.

 

I have added images taken with narrow B bandpass filters in order to try to detect auroras. None is seen here certainly but the filters prove very effective for subtle white clouds detection especially the 425.

Received: 22 July 2018 at 00:16 JST

 

Hi all,
After weeks of work, here are some first results using a Star Analyser 100 on Mars. The idea is not to identify chemical elements, as we do in spectroscopy usually, but to produce a color photometry work on planets using this low res spectrograph, in order to detect if possible color changes on planets.

 

This month was a superb occasion to test the idea on the martian global dust storm. As expected, the result show a very red spectrum, with almost no blue recorded. I hope to detect changes when the atmosphere will be completely clear in 2/3 months.

 

But right now, a notable difference can be recorded when focusing on the south polar cap. Although affected as well by the dust, the cap remains less red than the rest of the disk. Let's see how the spectrum will change when it clear as well from dust.

 

The data has been corrected both for instrument response and atmospheric extinction using nearby solar-like star Omega Sagittari (G5IV)

Hi all,

The best I could get out of Jetstream and poor seeing conditions last night. RGB data was too poor.

Best regards, Clyde

Hi, all

Up early this morning, but met by terrible seeing, and rather cool, 1 deg, weather.

Despite the low resolution, I am circulating, as this view shows the dark gholeh in the SPC quite nicely.

Best regards, Clyde

Here's an IR image of Mars from this morning in reasonable seeing.
Valles Marineris is the bright horizontal feature rising at left,
South polar region at bottom.

 

The visible features appear pretty much identical to yesterdays image in the same IR channel.

The seeing today was perhaps slightly worse.

 

regards, Anthony

Hello,

Attached is a set of images of Mars taken on 14 July.

 

The telescope is a 245mm apochromatic refractor and the camera is an
ASI224MC.

The filters are band pass filters with a FWHM of 40nm.  The 889nm filter is a methane bandpass filter 8nm wide.

The images were taken from Melbourne Australia.

 

Regards

I am using an 805nm filter now on Mars, a slightly longer wavelength than I was using before.

 

On the 15th,  the central meridian corresponds to a dark patch known as Laestrygonium Sinus. In the north are the light-coloured plains of Elysium and Amazonis. 

On the 19th, Mare Sirenum is the dark area in the middle south, but the area now doesnft look like it does on maps at all. Olympus Mons in the N looks dark.

Thanks for this, Clyde.

I agree that there are some active, dense, dust cores that are shown in your image.

 

Since the seasonal SPC should regress more rapidly than usual if the sublimation rate is increased, the way to find out whether the sublimation rate is increased is to observe the regression of the edge of the SPC. Although the warming of the atmosphere by the dust's absorption of sunlight gives us a reason to think the sublimation rate might be increased, it could also be asserted that the dust covering the cap decreased insolation so that the ground is colder and the sublimation rate should be decreased!

 

Note that the NPH is prominent. I interpret this to mean that it's at a higher altitude than the mixing layer -- i.e., stratospheric -- as the mixing layer is warmed by dust. Maybe I'm wrong about that.

Hi all,

Mars on 18 July, looking down on the Tharsis, Solis Lacus and Valles Marineris regions.

To me, it looks like we are seeing more detail starting to show in the RGB images.

The NP region is incredibly bright and difficult to process.

Quite a lot of structure can be seen on the SPC.

Best regards, Clyde

Hi all,

Trying to catch up on a bit of backlog.

Mars image set from 17th July, centred on Tharsis. It still looks to me that there are active dust regions.

I am not sure whether I am correct or not, but I have noticed that active dust storms seem to show, at least to some extent, in the G channel.

I note that the brilliant blue cloud extending off the SPC on the sunlit limb that has been with us for quite a while is now nearly gone. Does this indicate a reduction in the sublimation rate?

Best regards, Clyde

Hi all, some reasonable seeing for a short while this morning. Here's an image of Mars through a 750nm longpass filter showing increasing amounts of surface detail as compared to recent weeks so we might hope that the dust is slowly settling.

cheers, Anthony
