解説（安達）/ Comment by Makoto Adachi
All surface details visible in the image were also visible at the eyepiece (188x and 625x).

Seeing 8/10 Trans 6/10

Marte nei giorni dell'opposizione... quasi alla minima distanza,quasi alla massima grandezza.
Interessanti formazioni nuvolose lungo i bordi (biancastre),evidente il rilievo dell'Olimpus Mons,
in basso a sinistra. Polo sud ormai ai minimi termini (l'immagine ha il sud in alto).
Mars in the days of opposition ... almost at the minimum distance,almost at the maximum size.
Interesting cloud formations along the edges (whitish),evident the relief of the Olimpus Mons,
in the lower left. South pole now at a minimum (the image has the south at the top).
Marte ripreso due sere fa,quando era in posizione molto pi alta in cielo rispetto all'immagine precedente.
Mars imaged two nights ago,when it was much higher in the sky than the previous image.
[Fattinnanzi Cristian : Montecassiano ITALY]
seeing wasn't so good this morning so the imaging was limited to IR650 longpass.
This image shows Solis Lacus as the prominent "Eye of Mars" feature near the centre of the image,
with one of the solar systems deepest chasms making up the northerly edge (Valles Marineris).
Olympus Mons is rising at top left,and the south polar cap is present at the bottom of the image.
Some cloud can be seen on the northern and eastern limbs.

After many days of clouds and rainy finally I was able to image and observe Mars again.
Air was crystal clear hence seeing quite unstable.
By turning the motors off I was able to determine the celestial North and the Mars axis of rotation,
which was useful for me to place WinJupos measuring mask. So note on top of image there's true planetary South.
Beautiful delicate limb clouds were visible also at the eyepiece in B light.
[Vincenzo della Vecchia : [Aversa,Italy]
I took my chances relatively early yesterday evening,as there was cloud forecast for later,
and although seeing didn't look particularly good,I managed a full data set.
Olympus Mons is bright at lower left with cloud over the Tharsis Montes and Valles Marineris at left.
There are more subtle clouds extending across the Amazonis region towards Elysium.
[Clyde Foster:Centurion,South Africa]
[Jacques VAN DER MEER: La Ciotat (13) France]
Whitish clouds along western limb and band of clouds near eastern limb,east of Syrtis Major.

Finally we had clear skies last night and I was able to make two drawings of Mars.
Initially the seeing was rather average,but it did improve much later on.
Drawing 1:
・The first thing which caught my attention was the bright white region on the preceding limb.
These I think are bright clouds over the shield volcanoes Arsia Mons and Pavonis Mons.
It did seem that the cloud seemed to extend beyond the terminator giving the impression of a projection,
however seeing was only average and it may simply have been a contrast effect.
・SPC now quite small. Mare Chronium well seen with Thyle I and II just north of the SPC.
・There seemed to be small bright clouds visible in Electris and Eridania.
・Both the Mare Sirenum and the Mare Cimmerium showed a great deal of fine detail.
As usual,the region immediately north of these features were quite bright.
・Trivium Charonis and Cerberus were present but not particularly bright.
Elysium was also present but didn't appear to be particularly conspicuous.
・Vague streaks in Eumenides and to the far north,the NPH was present and bluish in colour.
Drawing 2:
・The SPC is much harder to see at these longitudes.
There didn't seem to be any sign of the limb projection observed in drawing 1-
however the clouds over the shield volcanoes have now rotated onto the night side and are not as conspicuous.
・Mare Cimmerium well seen- a lot of fine detail was present.
Near the following limb,the edge of the Mare Tyrrhenum can be seen
・Elysium now better placed on the disk but still not particularly conspicuous.
・Vague shadings present just south of the NPH.
[Paul G. Abel:Leicester:United Kingdom]
The image was steady and free from low level turbulence,
but it had the characteristic softness that a fast jetstream imparts,preventing any scrutiny of very fine detail.
The SPC appeared uniformly oval and a little dull.
Evening cloud was obvious over Arsia Mons,and Olympus Mons,the former being a much larger and more elongated patch than that over Olympus.
There was also mist along the evening limb.
Morning cloud again extended onto the disc obscuring parts of Mare Tyrrhenum.
The NPH was bright bluish white,and appeared offset a little towards the morning side of the disc.
Using the W80a filter there appeared a much brighter slither of white right on the northern limb,
so bright that I wondered if it was possible that I might have caught the edge of the new cap shining through the hood,
or possibly the hood was just particularly bright there.
[Chris Nuttall : York,UK]
I wasn稚 expecting much last night,Seeing wasn稚 too bad,but I only managed to capture 5 AVI痴 before the clouds rolled in,
two of those turned out to be fairly good. So the attached is the result of 2 x 4,000 frames de rotated in Winjupos,
each AVI just 2.5 minutes in length (about 22,000 frames).
[Kev Wildgoose:Oswestry,UK]
[Stephen James O'Meara : Maun,Botswana]
The images of October 8th and 9th show a lot of clouds above the Tharsis region.

Elysium on view with Elysium Mons and Hecates Tholus seen as bright spots.
[Damian Peach: Loudwater,Buckinghamshire,United Kingdom]
[Efrain Morales Rivera Aguadilla:Puerto Rico]
Hellas and Syrtis Major to Sinus Sabaeus are well positioned in these images.
Mars appears very clear with the exception of some limb clouds and the NPH. A white cloud extends over Libya.
[Gary Walker:Georgia:USA]
This is Hellas,Syrtis Major,and The South Pole of Mars in good seeing and transparency on the nearest that Mars is to Earth this opposition.
