Hi all,

Rather low-res RGB and IR image set from this morning. Maybe I must start calling these conditions haverageh for this time of yearc..

Clouds are less prominent over the Tharsis volcanos. I did note that in the B image, there appears to be two bright spots in the South Polar Cap region. Although at this resolution detail is suspect, any comments would be welcome.

Best regards, Clyde

Hi all,

RGB/IR image set from this morning. Despite earlier afternoon conditions, cloud remans over Olympus Mons, as well as Ascraeus Mons. Reduced cloud over Pavonis Mons, and no significant cloud noted over Arsia Mons. Late afternoon cloud is seen over the northern regions of Valles Marineris which is now coming into view. A hint of possible cloud over Alba Patera. NPC Olympia outlier is seen.

Best regards, Clyde

Hi all,

Rather frustrating seeing this morning-soft and shaky, making focussing difficult, but the Olympus Mons(almost central now) and the Tharsis clouds are still well seen.

I have been informed that gdouble NPCh is likely due to the Olympia NPC outlier.

Best regards, Clyde

Hi all,

Mars image set from this morning, under poorer conditions, with cloud remaining over Elysium.

There also appears to be cloud over Tharsis and Syrtis Major. I believe this is the season of broad equatorial cloud.

In the B image, I suspect that there may be an interesting cloud structure SW(above right) of Elysium, with possibly two curved clouds. However at this size and resolution, difficult to confirm.

Best regards, Clyde

Hi all,

A beautiful fresh morning with some reasonable conditions. Jupiter and Mars are getting close now. Cloud over Elysium and I suspect NPC outlier may be detectable. Possibly a hint one of the gantennaeh that extend of M Cimmerium in the IR image. Hesperia is showing nicely.

Best regards, Clyde

Olympus Mons can be faintly seen as a brighter patch at upper right.

Hi all,

I hope that you were all able to enjoy a happy Xmas with your loved ones.

I was privileged to spend another Xmas with my 92 year old dad and my sisters family down near Durban. On a further personal note, I am pleased to share with my Planetary friends that I proposed to Marina before Xmas and we will be married in March- nicely timed so as not to interfere too much with the Jupiter, Saturn and Mars oppositions a few months later!!

We returned home on Tuesday to cloudy weather, but I woke early this morning to clear skies and a nice late Xmas present- some nice seeing conditions!
The attached image set shows Syrtis Major to the centre left with possible cloud hanging over it(most noticeable in the G image)

Below Syrtis Major, a number of familiar features are detected including Boreosyrtis and a few albedo features south of Protonilus. The NPC is clearly seen.

Hellas seems to be filled with cloud, although there appears to be a dark indentation/feature towards the southern limb.

It would be nice if these seeing conditions stayed for a whilecc

Best regards, Clyde

Hi all,

Kindly find RGB and IR image set from this morning.

M Acidalium and Niliacus Lacus are prominent. Nilokeras and Lunae Lacus are also visible. Margarifiter Sinus, Aurorae Sinus and the Valles Marineris complex also detected.

Some indication of cloud over Tharsis on the bright limb. I am a bit concerned that the G and B images are similar- possibly an error on my part.

Best regards, Clyde

Hi all,

Despite Mars still only at 4.5h, a number of interesting features may be noted, including what appears to be some small discrete equatorial clouds:

a) The small NPC is evident

b) In the B image, there appears to be bright cloud over equatorial Tharsis. There also appears to be a more subtle broad band of equatorial cloud extending across the planet, as well as possible cloud at the NP region.

c) In the G image, the Tharsis equatorial region is also bright. Ophir/Candor also shows as quite bright. There are two small discrete features in the Chryse region adjacent to Margarifiter S, which appear to be clouds. There is also a subtle feature extending north-west across the Tempe region.

d) In the R image, it is interesting to note that the Chryse/Margaritifer  clouds are quite clearly seen, as well as the subtle Tempe feature, possibly indicating that there may be a dust component to these clouds?  Comments welcome.

Best regards, Clyde

Very nice work Anthony. Watching this cm longitude around Ls 117 will give you a chance to time the appearance of the north polar spiral clouds over Baltia-Mare Boreum.  The current Ls is a little early. Of the albedo features we can see that Pandorae Fretum is quite prominent. In writing up the 2014 report recently this feature was found to darken in response to Southern Hemisphere regional dust storm activity that crossed from NW of Hellas to Argyre in October hat year. We had such regional activity late in the 2016-17 apparition too, though there has been no encircling storm since 2007. This is definitely one of the best images of the current apparition, and others have done some impressive work too.
All the best from a snowbound

As noted in the IR image circulated earlier, Olympus Mons is central.
