Fascinating, Gary!
Good ol' Gomer Sinus, where Curiosity roams, is only half obscured, but look out, Curiosity, here it comes!

The irregular border of the SPC is incongruous unless one assumes that it is being obscured by encroaching dust clouds.

Interestingly, Syrtis Major is only partly obscured, still visible near the limb.

I'm on the lookout for false albedo features created by partial shadowing due to dust clouds.

Hi, all

At last some improved seeing conditions early this morning.

I am still monitoring the western edge of the main storm cloud.

1) Tharsis remains reasonably clear, with the Tharsis volcanoes and the western extremity of Vallis Marineris still clearly visible. Olympus Mons is the reddish spot at lower right.

2) Eastern Vallis Marineris remains bright with dust.

3) The left limb remains blanketed in the main dust cloud.

4) Dust is seen extending onto the SPC

5) I suspect that dust that has travelled around the planet from the other side of the storm is now seen at upper right

6) A sharp, linear cloud(CO2/ice?) extends from the northern limb at bottom.

7) Solis Lacus is also reasonably clear, but has dust activity changing on a daily basis, with a serpentine dust cloud visible today.

Best regards, Clyde

Dear Minami-sama,

I hope this email finds you well.

The Mars has been too far away for my small telescope. But finally my Mars season started.

Please find attached the Mars image from the last night (14 June 2018). When I first saw the image I was disappointed since no pattern appeared on the Mars.

Then Murakami-san told me about the big storm. So turned out that I was quite lucky to capture the event. Hope you find my image useful in some way.

Hi,all,

Despite clear forecast, I woke to find almost totally overcast conditions. I was limited to trying to catch cloud affected IR data in the small clear gaps.

I was able to maintain the CM that I have been monitoring the last few nights, and it appears that Solis Lacus and the Tharsis plateau are continuing to resist the western movement of the storm.

It is interesting that the Daedalia (I believe it may be Memnonia) bright outbreak from yesterday is only just detectable today.

Vallis Marineris remains bright with dust.

A dark feature is noticeable in the Nilokeras region through the dust.

Luna Lacus/Ganges appears to still be clear, but right on the edge of the storm.

Although not confirmed, due to this single wavelength capture, I suspect that the whole of the far northern regions may be dust laden.

Based on the NASA Dust storm/Opportunity rover press conference yesterday, which highlighted a few interesting and unique aspects of the storm, we can expect the eastern side of the dust storm to appear on the right of the image in coming days, confirming the global status of the storm.

Best regards, Clyde

Clyde --

Thanks for this. I agree with all you say, except that the bright dust focus you ascribe to Daedalia is in Memnonia instead.

With large dust storms like this, there are three ways in which dust spreads: (1) by advancement of existing dust clouds, (2) by new clouds forming, usually on the outskirts of existing clouds, and (3) by a diffuse, spreading haze, presumably at a higher level in the atmosphere, of which the margins cannot be clearly discerned. All three of these methods are now evident in this storm, and indeed, in your sequence of images.

The diffuse haze is in the northernmost regions visible, now obscuring detail all around the planet at that latitude. Incidentally, Frank Melillo's image of June 12 suggests that the SPC is partly obscured at longitudes near 250 degrees. I'm hoping for some confirming images showing or refuting that, today.

Excellent documentation. Keep on recovering!

Hi all,

It is a pity that I remain with mediocre seeing conditions, but thankfully the skies remain clear, and I continue to adjust my imaging time to monitor the dynamic changes on the western edge/front of the dust storm.

I note:

a) The Main storm covers approximately the far left quarter of the planet, blanketing that region.

b) Significant change over Solis Lacus where the multiple dust cells of yesterday have been replaced with a dust tendrile extending from the main storm

c) Vallis Marineris appears to still be bright with dust.

d) Although the Tharsis plateau almost appears to be holding back the westward movement of the storm, it does appear that the region near the NP may be experiencing dust

e) There is a new , bright, concentrated outbreak in the Daedalia region

Hi all,

Here are some images from May 4th. Despite some good seeing at times, this has to go down as one of the most frustrating sessions i can remember in recent times.

There were six (yes six!) rain showers over the course of the session playing havoc with the seeing (and my patience!) On top of that constant streams of cumulus clouds made getting clear image sequences difficult. Despite this (and having been awake for 28hrs) i persisted. Here are the results.

Hi all,

A capture just before midnight last night , with ongoing poor (and frustrating!) seeing conditions.

However, I believe the image set nicely captures the current western extent of the dust storm. I am considering planning my imaging to target this region over the next week in order to monitor the edge of the storm.

The dust appears to extend onto the SPC at upper left.

There are also a number of dust concentrations over Solis Lacus as well as one adjacent to the SPC.

Tharsis appears to remain reasonably clear at this point.

As always, hopeful for improved seeing in the coming days.

It's interesting that Valles Marinaris is outlined by its bright dusty content.

In your image, I'm puzzled by a medium-brightness, broad line extending N-S across Bosporos, western Mare Erythraeum, and Aurorae Sinus. This is an unusual appearance for this area. Could it be dust?

If so, it would be an unusual appearance for dust. Let's pay attention to see if it changes in the next few nights.

Notice that Thaumasia is essentially gone, not only on your image, but on others. Thaumasia was darker than usual near the end of the last apparition, but not so dark as it is now. It's as though Solis Lacus and the dark features east of Thaumasia have swollen and, together, have swallowed up Thaumasia.

Hi all,

Mars last night. I was up a bit earlier(Mars at lower elevation), but was met with what can only be described as terrible seeing conditions. IR came out best, but I was limited to using only 10% of the RGB channel captures, and it was a struggle to get anything decent out.

Tharsis appears to remain relatively clear(although maybe lower contrast than normal?). The main storm region is still to rotate into view , although there are hints of dust activity along the terminator, most notable along the Vallis Marineris complex.

The most notable feature is the dust activity over Solis Lacus , which appears to have a concentrated centre surrounded by a wider dust cloud.

Hoping for better seeing in the coming days.

Hi all,

As you would have noticed , I have been out of action for over a month, for two main reasons, one good, and one bad!

I was privileged to be invited to attend, and do a short presentation at the Europlanet Juno workshop 10-11 May in London. It was another amazing experience, where I was able to personally meet and interact with a number of leading planetary imagers.

Unfortunately immediately after the Workshop, I had an accident, resulting in me being hospitalised for 3 weeks in London with a fractured pelvis, requiring me to undergo an operation.

I returned to South Africa just over a week ago and am now hopefully in a position where I can start imaging again. I have been following the dust storm developments with interest and should be in a position to monitor the region over the next week or so.

Attached my first Mars image set following my accident, from last night, just catching the western edge of the recent large dust storm. Tharsis seems to be reasonably clear, although the northern region may be hazy. I believe, based on Anthony Wesley's beautiful image captured earlier in the day, that the bright region at upper left is one of the extensions of the large dust storm that initiated in the northern hemisphere and which appears to have extended as far as the SPC.

Its good to be back imaging!

Hi David, I just did a quick test here, with these results...

I used a ser video recorded in firecapture from May 28. The video starts at 12:44:25 and finishes at 12:45:40 through a red filter. Firecapture names the video using the WJ naming scheme and the midpoint of the capture, so the video is named 2018-05-28-1245_0-red.ser.

When I process this in AS! then the filename of the output file is 2018-05-28-1245_0... which is the midpoint of the capture.

I don't know if AS! recalculates the midpoint of the capture from the video (in the case of SER where timestamps are available) or if it just used the original filename. Emil could answer this, so I've added him to this email chain.

cheers, Bird

I have no idea what the answer to David's question is, but I attach an image I grabbed last night using a mono Skyris 618 in integrated light with about 1000 frames. I was struck by some moments of delightful seeing through the eyepiece from South West London despite the dismal altitude of Jove himself and hastily captured this using a hand-cranked old Irving mount and an interesting f7.5 11.75" Newtonian primary originally made by Wildey but later refigured down from f10(!) by Hargreaves & Cox (for those tragically interested in these matters). Trees then intervened, but the GRS looked distinctly orangey to me through the eyepiece. There was a fairly interesting dark barge in roughly the same longitude as the GRS in the NTB.

Dear all,

Here’s some recent images.

On 30 May

On 1 June

On 2 June

I’d like to ask this list something that has been puzzling me about Autostakkert! and WinJupos.

The filename that AS! generates for images if you ask it to name according to the WJ convention is based on the start time of the video. But the longitudes that it gives in the text file are those from the middle of the capture, not the start. So, if you then derotate images in WJ, the timings it uses are the start timings that AS! has put in the filenames. This means that the derotated image will be given a name that corresponds to a start time of an image that is the average of the start times of the constituent images, i.e. it will not correspond exactly to the true longitudes on display. Eg. if all your videos take 60 seconds, the true timing of each of them is 0.5 minutes later than that in the file name, and the true timing of the derotated image will also be 0.5 minutes later than that in its file name. But you can get the exact mid-capture longitudes from an AS! text file, e.g. if you derotated 5 images, they will be the longitudes given in the text file for the third image.

So, people who analyse these images, what are we supposed to be doing? Are we supposed to be quoting the true timing of derotated images, or the one that WinJupos puts in the filename? Are we supposed to be quoting longitudes that correspond to the filename that WinJupos gives, or the ones given in the AS! text file, which will correspond to some time later?

What I am doing is quoting the WinJupos filename times, but giving the exact CM longitudes, as I get the feeling this is what others are doing.

What are the people measuring the images doing? Surely they can only disentangle this if they know how long we took the individual videos for. But most images I see don’t contain this information.

Yours,

David ARDITTI (Edgware, Middx. the UK)

"After a year’s hiatus, the Curiosity Rover is hopefully getting back to its normal schedule of drilling into rocks at Mars’ Gale Crater.

Hi all,

Some moments of good seeing on the 28th allowed for a lovely view of the Syrtis Major region of the planet. Very little cloud activity.

All,

This is a quick rendition of Jupiter at 5.1 microns, with the GRS front and center, from NASA’s Infrared Telescope Facility using SpeX last night…dodging clouds. We hope to get Juno’s PJ13 longitude tomorrow morning. Then I dash to the airport to pursue even longer wavelengths from Subaru. Needless to say, this is a very unusual configuration around the GRS. There is some evidence for the beginning of EZ brightening in a very narrow and faint band.

Hi all,
Here are some images taken during the night of 15/16 May 2018.

Seeing was quite good for the height of the planet.

Hi all,

Again some reasonable seeing on the 27th. A nice view of Sinus Meridiani and surroundings.

These are at the typical low resolution, even in IR, that I get from here this year, but as John Rogers urges it, even for us northerly observers, I thought I’d send them out. I do seem to regularly capture the AWOs.

Well-done again to the organisers of the RAS Juno conference, which was very enjoyable, particularly to meet all the Jupiter enthusiasts from all parts of the globe.

Hi all,

Reasonable seeing on the 20th. Mars looks rather misty/hazy across this hemisphere. The angular size finally reached 10".

Hi all,

A rather different image of quite an unusual nature!

Binary star pair Porrima changing over a 15yr period.

The most recent image taken just a week ago. The 2005 image they were at their closest and only just resolvable.

Received: 19 May 2018 at　06:42 JST

Hi All,

Just to see if more information on the cloud movement could be obtained,

I've been experimenting with morphing the frames obtained the other day to give a smoother appearance.

It seems to have worked to some extent.

I get the impression that there are two layers of clouds moving at different speeds;

this could be an illusion though!

See what you think.
