22時半頃になりやっと晴れ間が出来始めましたが
シーイングは悪く、更に急速に悪化している感じでした。
再接近なので、記念として無理やりの撮影撮影です。

Precious few cloud breaks so far this winter - I had one lone opportunity for
Mars observation Friday night. This RGB image captured with my 10"
mak/cassegrain at f45ish,4:25UT on January 23 was the best of the lot.

Seeing wasn't the great this evening because I wasn't able to cool my OTA properly. The final image however came out okay
Syrtis Major is prominent in this image. Syrtis Major is well resolved but there are no blue clouds today. These seems to be some clouds around the Hellas region.
Note the dark arc in the North Polar Cap (NPR). There are faint clouds around the Ismenius Lacus Region. Where there's a prominent cloud at Chaos.

火星時間に間に合うように晴れたのですが、２セット撮影すると曇ってしまいました。
雲が無くなり晴れたときには、ベランダから見えなくなっていました。

I hope that you and your family have been doing well.
I made an observation of Mars under average seeing conditions (5/10) with brief moments of steady seeing (7/10).
The amount of detail visible was impressive considering that Tharsis was visible.
I made sectional sketch of the Mare Eryhtraeum/Solis Lacus regions which appeared mottled and with fine detail.
I welcome any comments on my observation.

05:15 U.T. (CM 132.4*W,Wratten 30 (Magenta)): The North Polar Cap (NPC) appeared brilliant (10/10) surrounded by a dark
to dusky (3-4/10) collar comprised of Lemuria. Tharsis appears dusky to shaded (4-6/10) and mottled on the central meridian (CM).
Ceraunius appears as a dusky (4/10),broad streak on the CMover the northern hemisphere.

Nilokeras (4/10) and Lunae Lacus (4-5/10) are visible extending from the South-following border of Mare Acidalium.
A very bright (8/10) cloud is visible over Tempe. Ganges appears as a broad,dusky to dull (4-5/10) band extending
between Lunae Lacus and Aurorae Sinus (3-4/10). The Propontis Complex appears dark to dusky (3-4/10) over the North-following
(Nf) limb. Solis Lacus appears dark to dusky (3-4/10) with Calydon (4/10) and Eosphoros (4/10) projecting from it's northern border.
Agathodaemon (Coprates) is visible projecting from the following border of Aurorae Sinus.
Aonius Sinus is visible as a dusky (4/10) wedge towards the southern limb. Mare Sirenum appears dark to dusky (3-4/10)
with dull (5/10) projections extending over it's northern border appearing to connect to Valhalla (4-5/10).
Trivium Charontis is visible over the following limb and appears dusky (4/10). Evening limb haze (ELH),
morning limb haze (MLH),and the southern limb appear very bright to extremely bright (8-9/10).
05:45 U.T. (CM 139.7*W,Wratten 80 (Blue)): An very to extremely bright (8-9/10) cloud is visible over the preceding limb
over Mare Acidalium. A bright to very bright (7-8/10) cloud is visible over Chryse/Xanthe and projecting into Tharsis.
A bright to very bright (7-8/10) cloud is visible over Tempe. A very to extremely bright (8-9/10) cloud is visible over
Elysium on the following limb. A very to extremely bright (8-9/10) cloud is visible over the Propontis complex region on
the following limb. Evening limb haze (ELH),morning limb haze (MLH),and the southern limb appear very bright to extremely
bright (8-9/10).
I made a sectional sketch of the South-preceding (Sp) limb which contained Mare Erythraeum and the Solis Lacus regions.
Mare Erythraeum appeared dark to dull (3-5/10) and mottled. Agathodaemon (Coprates) appeared as a dark to dusky (3-4/10)
projection from the following border of Aurorae Sinus (3-4/10). Tithonius Lacus appeared as a dark to dusky (3-4/10) "knob"
at the following end of Agathodaemon. Baetis appeared as a dusky (4/10) projection from the following border of Aurorae Sinus.
Solis Lacus appeared dark to dusky (3-4/10) with Calydon (4/10) and Eosphoros (4/10) projecting from it's northern border.

The best of luck to you,your family,and the members of ALPO Japan and in your own imaging of Mars.

Mars nice and high in the sky and absolutely unmistakable amongst the stars of Cancer. The sky was largely cloudy at the start of observations,however by 2314UT,it had cleared sufficiently to allow a drawing to be made.
Drawing A: Acidalium now well on view. I think my previous rendering of this regions was slightly wrong- tonight's drawing is much more accurate. Proc. side of Acidalium seems darker and the whole regions has the appearance of having been 'rotated' a 10 degrees clockwise or compared to the 2008 observations. Mare Erythraeum well placed,many fine details here,Solis Lacus coming into view on fol. side of the disk,Sinus Sabaeus present on Proc.. limb. Chryse very bright.
Drawing B: Intensity estimates (BAA Mars Section scale)
NPC Drawing: It is clear that the cap is starting to break up and sublime now. Baltia present within the cap,and the whole region had many subtle tones to it; alas seeing was not quite good enough to capture them all reliably!
