Hi all,
Reasonable conditions towards sunset yesterday afternoon.
Syrtis Major
is to the right of centre, with
Hesperia is at upper left.
Boreosyrtisis at lower centre.
Some cloud appears to be present over Elysium on the left
limb.

Hi all,
I had some clear sky yesterday afternoon after a few days of
cloud. There was a strong wind blowing, and the session was only salvaged by a
frame rate in excess of 400fps, with the planet moving all over the chip’s ROI.
Other than that there was significant jetstream.
The RLP and R came out surprisingly well, with Syrtis Major extending up from centre. The B remains
challenging. Boreosyrtis is evident lower left of
centre, with Syrtis Minor at upper left.

Hi all,
I’ve been prevented from imaging for a number of days due to
afternoon cloud.
Attached an image from this afternoon,
about 50mins before sunset. Conditions were difficult with wind at ground level and
strong Jetstream overhead, so I stayed with the
R610LP.
Syrtis Major
is to the left with Sinus Sabeaus and Sinus Meridiani extending across the planet above centre.

Hi all,
I started yesterday afternoons session about an hour before
sunset to catch Mars at higher altitude and also to try and capture RGB before
some forecast cloud.
Although far from ideal, I did manage to get a barely
acceptable B, indicating some cloud along the morning terminator.
Sinus Meridiani and Sinus Sabeaus are at upper left, M Erythraeum
at upper right, Niliacus Lacus and M Acidalium at lower right and Margaritifer
above centre.

Hi all,
Light cloud prevented decent G and B captures yesterday
afternoon, but I did manage limited R610LP and R captures, which I have
presented for comparison.
Niliacus Lacus
is again central, with M Erythraeum at the top and M Acidalium towards the bottom.
Margaritifer Sinus

Thanks to interaction with, and feedback from, the NASA
MRO/MSSS team, I was able to confirm that the lightness along Valles Marineris is in fact a
result of dust activity arising from localised dust storms that have moved
north from the Solis Lacus region over the last few days. My
sincere thanks to Dr B Cantor of Malin Space Science
Systems for this feedback.

Hi all,
I had some interesting seeing conditions well before sunset
yesterday afternoon, with some short periods of really nice seeing interspersed
with a total disintegration of the image on screen.
Unfortunately the good periods didn’t extend towards sunset
and I was unable to capture any decent RGB data.
Niliacus Lacus
is central with Mare Acidalium extending below it. Margaritifer/Indus are quite
obvious. Hydospes is also noted.
Sinus Meridiani is seen on the
upper left limb.
I again note the lightness of eastern Valles
Marineris region extending below Mare Erythraeum.

Hi all,
I had some reasonable pre-sunset conditions yesterday
afternoon, although the B was barely usable.
Mars has finally dropped to 4.0”.
Nilokeras is
central.
The R610LP is interesting, and I am wondering if there may
be some dust activity along eastern Valles Marineris.

Hi all,
Following a few evenings of cloud, conditions, particularly
for G and B, were not good enough for an RGB.
Higher contrast features have rotated into view, with M Acidalium and Niliacus Lacus to
the lower left. Nilokeras is almost central with a

Aurorae Sinus
is upper left of centre with Valles Marineris extending to its upper right. Margaritifer

Hi all,
A very brief R610LP session this
afternoon under strong wind conditions. Very limited usable data.
Valles Marineris is upper left of centre with Solis Lacus near the
upper left limb. Auroarae Sinus and Nilokeras are towards the left limb.

Hi all,
Image set from yesterday afternoon, shortly after sunset.
Olympus Mons is just to the right of centre. The dark
streak to the left coincides with Lunae Lacus-Ganges,
likely enhanced by the bright limb. The darkish feature to the lower left of
centre has been noticeable for a few days now, and appears to lie in the Nilus region.
Valles Marineris is on the upper left limb and higher contrast
features should come into view in the coming days.
I am wondering if the SP Hood is not becoming visible (G)?

Hi all,
Another bright sky image set from yesterday afternoon with
the RGB captured 7 mins before sunset.
The RLP, R and G conditions were decent, but the B was poor,
making interpretation of the NP region difficult.
The “doughnut” of Olympus Mons can
just be made out to the left of centre. Mare Sirenum
is near the upper limb. Propontis I is near the terminator at lower right.
The NPC remains quite distinct in the RLP, R and G. In the
R, the light spot to the right of the NPC appears to coincide with

Another twilight attempt on Mars.
The R and R/IR remain acceptable,
but the G and B captures are progressively more difficult in the light
background and low altitude, making the RGB challenging, and somewhat
unreliable.
Propontis I can
be seem lower left of centre, with Propontis II best
seen in the R below it.

There appears to be bright cloud over Olympus Mons on the left limb.
