The north of Ausonia (260W,-30) and the northwest side of Hellas (290W
-50) are brightly remarkable in the image of Neichi. Especially, the
bright spot where Ausonia (260W,-30) is bright is like white like white
clouds. It is the same one as the white cloud that Yunoki recorded on
October 7. It has been understood to see this cloud at noon on the
Martian surface. NHP is clearly recorded. NPH in the vicinity of Mare
Acidarium (30W,+50) seems to have become light. Carlos.E. Hernandez
reported on a detailed appearance on the Martian surface. White clouds
of minor latitude such as Arsia Silva (125W,-5) and Phoenicis Lacus
(110W,+10) are understood well in the image of D.C.Parker. A remarkable
change is not seen though the image of Damian Peach records Chryse (35W
+10) and the vicinity of Xanthe (50W,+10). The same appearance is shown
though Cristina Cellini is observed. (reported by 8 observers)

A set of Mars images taken this morning, Oct 11th, from the UK, is attached.
Seeing was fairly poor, but not totally hopeless.
Mare Erythraeum longitudes are best presented. Solis Lacus is near the
morning limb.

Temp. a mild + 15 C (!) No dew. Transparency poor. Breezy.
Much drifting cloud.

finally some good transparancy but louzy seeing, Ir image is the only one to bring some details, at least Mars has sufficient diameter to show something. The NPC seems to shrink somewhat

I made a pair of observations of Mars on October 11, 2005 (05:30 and 06:15 U.T.) under average to good (6-7/10) seeing conditions. A wealth of detail was visible over the Martian disk that was almost impossible to render. The Solis Lacus region was very complex as depicted. A W-cloud was noted over the Tharsis region, especially in blue light (Wratten 38A). I welcome any comments that you or any other members of ALPO Japan may have on my observations.

Notes:
05:30 U.T. (Left image, IL/W30): The South Polar Cap (SPC) was very small and brilliant (10/10) surrounded by a dark (3/10) collar. Mare Australe appeared dusky to dull (4-5/10) and mottled. Solis Lacus was visible towards the preceding limb and appeared dark to dusky (3-4/10) with northern (Geryon (5/10) and Calydon (4/10)) and southern (Ambrosia (5/10) and Bathys (4/10)) projections over Thaumasia (7/10). Nectar (3/10) was visibly connecting Solis Lacus to Mare Erythraeum (3-4/10). Agathodaemon (Coprates) was visible as a dark (3/10) projection from the preceding limb connecting to a partially obscured, by clouds/haze (8/10), Tithonius Lacus (Melas Lacus (4/10) and Noctis Lacus (5/10); also comprising Echus Lacus, Hebes Lacus, and Ius Lacus which were not visible). Bosporos Gemmatus was dark to dusky (3-4/10) with condensations. Aonius Sinus (3/10) was visible on the CM with Phasis (4/10) projecting to the north. Phasis appeared to connect to a curvilinear and dusky (4/10) band from Tithonius Lacus which then completed a ring complex surrounding Solis Lacus. Daedalia appeared bright (7/10) between Phasis and Araxes (5/10). Mare Sirenum was visible following the CM and appeared dark to dusky (3-4/10). Sirenum Deprresio appeared a dark (3/10), circular albedo feature over the south-following border of Mare Sirenum. Phaethontis appeared bright to very bright (7-8/10) south of Mare Sirenum. The western (following) border of Mare Acidalium (5/10) was partially obscured by clouds/haze (8-9/10). Tharsis appeared shaded to bright (6-7/10). Arcadia and Amazonis appeared dusky to dull (4-5/10) and very mottled. A bright (7/10) patch was noted within this region which may represent the area of Olympus Mons (no specific brightening was noted over this area using the blue filter(W38A)). Dusky to dull (4-5/10) albedo features were noted over (or visible through) a semi-transparent North Polar Hood (NPH, 8-9/10). Thin and extremely bright (9/10) morning and evening limb hazes (
MLH and ELH) were noted as well.
06:15 U.T. (Right image, W38A): The South Polar Cap (SPC) appeared small and brilliant (10/10). Solis Lacus and Mare Sirenum were visible as dull (5/10) albedo features. A very bright (8/10) W-cloud was noted over Tharsis, north of the Tithonius Lacus complex. Arcadia and Amazonis appeared to be obscured by a very bright to extremely bright (8-9/10) haze. Extremely bright (9/10) morning limb haze (MLH) and evening limb haze (ELH) were visible as well.

Here are some images from Oct 11th. Poor seeing yet again, with the jetstream close by. Similar details to yesterday with some changes.
The southern polar cloud of yesterday is less prominent, and some interesting clumpy cloudiness is present within the NPH. Northern Nilokeras remians obscured in Red. Chryse is dusky in Red. Weak clouds over Tharsis into Candor/Ophir. The Arsia cloud is not present toward the evening limb.
