Hi all,

Mars midnight session last night, with what is meant to be Syrtis Major central, and Hellas basin upper central.

The IR definitely seems to cut through the dust, at least to some extent.

The SPC is heavily affected by the dust, and there is some finer dust detail on the bright section of the cap.

Best regards, Clyde

Hi all,

Image set from this morning, with conditions a bit improved.

Quite a lot of subtle features are visible in the IR image, and to a lesser extent in the R, possibly indicating structure in the dust.

S Meridiani and Margaritifer are still heavily obscured.

Vallis Marineris can just be made out through the dust

There appears to be dust on the SPC.

I have increased the size of my template to accommodate the upcoming opposition- things could have been looking very different, but it has been fascinating monitoring the dust storm.

Received: 25 June 2018 at 15:20 JST

Hi all,

Over the period 9-23 June, I was able to monitor the Vallis Marineris/Solis Lacus region, which corresponded to the western front of the major dust storm that had initiated in Mare Acidalia at the end of May.

The main dust cloud from this storm can be seen blanketing the eastern(left) limb, particularly well seen from 11-15 June, and appearing to become more diffuse in the following days.

Very dynamic changes were seen on a daily basis, with dust activity, which appears to be various extensions of the original dust cloud, active across Solis Lacus over this whole period.

However, multiple, local, concentrated, albeit short lived, dust outbreaks were also see during this period, most notably:

a) Directly over Solis Lacus on 10 and 11 June

b) Very bright outbreak in Memnonia 12 June

c) Two concentrated outbreaks just south-west of Vallis Marineris on 19 June, with a possible further, less concentrated outbreak in Daedalia/Memnonia.

d) What appears to be a major dust outbreak to the south, west and north of Solis Lacus (captured by other imagers on previous days) as seen on 23 June. At this stage the whole region had a very hazy appearance

I have deliberately left off detailed daily information, but can supply/add if required.

Not so clear this night, hazy, though seeing was fair. So I’m not quite sure if this rather diffuse-looking disk, with much less albedo contrast than on the 22nd, is really the state of Mars at the moment, or if it is due to my conditions. Solis Lacus and Mare Erythraem are hardly visible.

Hi,

Seeing this morning was terrible. Wasn't going to post anything but there appears to be a thicker band of dust in Mare Sirenum showing up in the IR image and in the color at times on the monitor.

Dears,

Jupiter under a correct seeing.
"STB Ghost" is setting (on the right, it appears as a very dark streak including in methane absorption band) with white oval A5 south of it, and "STB spectre" very faint is getting closer to the central meridian.
A small brown barge is close to the CM, South of the SEB, and a dark spot chain is visible in NTB.
Io is almost stationary, far from Jupiter while Europa closer moves faster.

Under less favorable conditions than 2 days earlier, images showing in lower resolution that the dust storm on Solis Lacus continued to spread (bright zone in the Southern hemisphere, close to the limb on the left). Infrared image shows some details nonetheless, and a bluish cloud is visible on the limb close to South pole.

Hi friends,
After a few days of major mail access and computer problems, I can send you images from the last days or weeks!
Here are my first four set of Mars images for the current apparition, showing the onset and developpment of major dust outbreaks over Solis Lacus, so the storm is really global now and not over at all.

This is probably the second occurrence of such an early spring global storm (at least in human history), with the great 2001 storm. To the difference of this last one however, the start of activity did not begun in usual southern locations (such as Hellas/SPC in 2001) but with a cross-equatorial dust event first lifted over Mare Acidalium on May 31th, wich is quite an interesting fact since usually those storm do not trigger global events.

Best regards,

Christophe

Dears,

Under a degrading seeing at dusk, my first Mars since 2 years. It's nice to see details on a terrestrial planet. The 3 Tharsis montes are visible left, and Valles Marineris is in the South hemisphere left of the dark zone at meridian. Its East part seems to be covered by a dust storm, bright in infrared, and very detailed, starting to spread south west in Solis Planum, and East towards Argyre Planita. North pole is whitish, and in the South we can see structures in the polar cap.

The SPC is showing quite a complex structure.

Dust is still obscuring large portions of this region, particularly to the east(left).

Structure is seen in Vallis Marineris, most notably Capri, and Eos and Ganges Chasmata.

Streaks of dust can be seen over the south polar cap, and Hellas Basin seems to be full of dust. Syrtis Major is almost completely hidden.
