Hi all,

Another cloud affected session this morning, although I did manage a full image set. I only caught one noisy IR as the cloud thickened. S Meridiani near the centre.

 

Best regards, Clyde

Hi all,

Imaging through variable cloud and in poor seeing, I stayed with IR captures. I caught 21x45s videos, most of which were unusable. There was a single capture that was significantly better than the rest, and I have submitted that only. S Sabeaus and S Meridiani coming into view.

 

Best regards, Clyde

Hi all,

Here are few images of various things i've recently processed. The re-worked Homunclus Nebula turned out very nicely and shows a similar appearance to the famous HST image of the object.

¤¤••••• Subject: Mars 24 January 0335UT  RGB IR

Received: 24 January 2022 at 19:54 JST

 

Hi all,

A first full image set of the apparition for me. I didn't have to contend with cloud this morning and although seeing was not that good, I captured a lot of data as the sky brightened, of widely varying quality.

I have presented the best of the individual channels, each derotated from the best captures. The B in particular was poor. Following my IR of yesterday, I had a few comments about the SPC (not well seen in IR under these conditions) being at its greatest extreme at about this Ls, so I was pleased that it is reasonably well seen in the G and RGB.

All I will say is thank goodness for WinJupos!

 

Best regards, Clyde

Great image, Clyde! Much detail. Thanx for this.

 

By the way, most of my messages to you in the last few apparitions have bounced.

We'll see from this message whether the problem persists.

Just an additional note, Richard. I captured 8x45s videos and derotated the best 4 of them together. I should have put that on my image.

Cheers, Clyde

Thanks Richard

Fully agree, given the conditions, that any interpretation should be handled cautiously at this point.

What was pleasing to me was that the on-screen image was really terrible, and I did not expect to get anything.

I know now that I can catch Mars just above the branches at this time in the morning (it will get progressively more dark as well), so if I have improved conditions, and clear skies off course (A current ongoing problemc.), I should be able to track reasonably consistently from here on. Mars is at a very nice latitude for me for the early part of the year, so will try and make the most of it before it heads too far north!

 

Cheers, Clyde

(I see I had a misspelling- Argyre, off course)

Dear Clyde

Excellent work. Although with tiny disk diameters and single images one must be careful, the main value of this image is in showing the continued existence of the albedo anomaly at Oxia Palus-Indus, continuing from 2018. As you say, Argyre is lightish. If you can continue we may be able to time the seasonal change from N. Polar cap to hood.....

All the best

Hi all,

Despite some cloud being forecast, I took my chances and snuck out of bed a bit early in surprisingly cool conditions for this time of year. It was a battle with the planet at 4.2h wobbling like a jellyfish through cloud and branches in brightening sky. But its Mars! For obvious reasons, I stayed with IR.  With some heavy handed processing, it was nice to at least make out some familiar features. Niliacus L and M Acidalium are in the lower part of the image. Maybe a hint of L Lacus. Chryse across the centre with Tharsis to the right. Also maybe a hint of S. Meridiani on the preceding (L) limb. M Erythraeum extends across the upper portion of the image with Aurorae Sinus and Valles Marineris. Itfs possible that Argyle may be showing as light at upper left. Very poor conditions, but a promising indication that under better conditions, there is a prospect of some reasonable results.

 

Best regards, Clyde

¤¤••••• Subject: Martian flares in 2022?

Received: 5 January 2022 at 02:26 JST

 

Dear colleagues,

   This month marks the third anniversary of our dear colleague and mentor Dr. Minamifs death, and the field of Mars studies continues to feel his loss (and many of us personally his warm friendship).  However, his legacies continue.  An article has appeared in the Journal of the Royal Astronomical Society, gMasatsugu Minami—the last great visual observer of Marsh (October 2020), and his notebooks have been deposited for safekeeping in the archives of the Lowell Observatory.  (I had begun scanning them for possible online publication as a resource for students of the planet, and especially those interested in Martian dust storms, but for the time being, work has been suspended because of Covid restrictions.  I had never had a chance to see the entire collection of Minamifs observations, and remain in awe of his skill in quickly and accurately recording the features on the planet and his keen eye for dust storm activity, which was completely without parallel).

   Dr. Minami was always a keen advocate for Japanese Mars observations, and regarded with especial esteem the work of his mentor, Tsuneo Saheki, whose flare observations electrified the world.  He was therefore especially happy to see the prediction and verification of the flare at Edom Promontorium in June 2001, under precisely the same conditions as the flare Saheki observed in July 1954.  It therefore gives me great pleasure to alert my Mars colleagues around the world with the announcement that another flare event is possible late this year.  According to calculations published by Jeffrey Beish of the Association of Lunar and Planetary Observers Mars Section, the Earth-Sun-Mars geometry will be very similar to 2001 except the Earth and Sun will not be quite as close to the zenith for an observer at Edom as they were in 2001, but 4.6 and 4.5 degrees from the zenith, respectively.  Universal Time is 9 hours behind Japan Standard Time. On December 5, 2022 at 10:27 UT (19:27 Japan Standard Time) Mars will have risen to an elevation of 34 degrees above the horizon for observers in Tokyo and will display an apparent diameter of 17 seconds of arc.  Therefore it is hoped that observers especially in Japan will undertake to make observations during the period of the flaresf possibility.

   Despite intensive commentary and numerous speculations, a completely satisfactory explanation of the flares has remained elusive.

   The following is the ALPO communication.

 

   Kind regards,

 

   Bill Sheehan

   Tom Dobbins

  

For those interested in catching a glimpse of possible "flares" from the surface of Mars (Edom) there will be a period when it will be possible to be seen when the De and Ds are coincident will be on or about December 05, 2022 (see Figure 7). The last time this event was recorded was during June 07, 2001 when the De = 1.8 and Ds = 2.5 and Mars was situated favorably in the sky for observers to record this rare event. The De and Ds will be very close together in this apparition; however, they will be slightly lower (-4.6 and -4.5 respectively) than in 2001 when the "flares" were seen. Detailed report of the 2001 event (Dobbins, Thomas A. and Sheehan, William (2001), "The Martian-Flares Mystery," Sky and Telescope, Vol. 101, No. 5, May, pp115-123) and "Solving the Martian Flares Mystery," Dobbins and Sheehan, ALPO Web Site.  See table below for dates when De - Ds +/- 1.0:

Hi all,

Here is a whole rotation movie and a whole planet map of Mars produced from my images obtained during the planets last close approach. All images used were between October 15th and November 11th, 2020. This is certainly the best map and movie ive produced of Mars in more than 20yrs of observing and photographing the planet.
