Night with good seeing and transparency of the sky,you notice the left of the
north polar cap probably a residue of sandstorm.

I made an observation of Mars on February 7,2010 under average seeing
conditions (5/10,with brief moments of 7/10). The amount of detail noted was
impressive and difficult to render at times due to the complexity of the
features noted. I welcome any comments that you may have on my observation.
Date (U.T.): February 7,2010
Time (U.T.): 03:30-04:30
CM (Degrees West): 019.5*-034.2*
Ls 048.3*,De 013.5*,Ds 018.3*,p 100%,13.9"
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 295x and 388x
Filters (Wratten): 30 (Magenta) and 80 (Blue)
Seeing (1-10): 5 (moments of 7),Antoniadi (I-V): III
Transparency (1-6): 5
Notes:
03:45 U.T. (CM 023.2*W,Wratten 30 (Magenta)): The North Polar Cap (NPC) was
brilliant (10/10) and has reduced in size (diameter) significantly compared to
previous observations. The NPC was surrounded by a dark (3/10) composed of
Ortygia and Mare Boreum. Mare Acidalium is visible following the central
meridian (CM) and appears dark to dusky (3-4/10) with condensations noted
within. Achillis Pons appeared bright (7/10) with a haze overlying it. Niliacus
Lacus appeared dark to dusky (3-4) with Nilokeras (3-4/10) projecting from it's
following border. Idaeus Fons appeared as a dark to dusky (3-4/10) "knob"
projecting northward from Nilokeras. Lunae Lacus appears to be obscured by a
very bright (8/10) haze over the following (morning) limb. Chryse-Xanthe appears
bright (7/10) without detail visible within it. Xenius Fretum appears over
Cydonia (7/10) as a triangular-shaped dusky (4/10) albedo feature. Sinus Sabaeus
and Sinus Meridiani appear dark to dusky (3-4/10) over the South preceding (Sp)
limb. Margaritifer Sinus appears a dark to dusky (3-4/10) triangular-shaped
albedo feature on the CM with Oxia Palus (4/10) visible south of it. Mare
Erythraeum appeared dark to dusky (3-4/10) and mottled with Pyrrhae Regio as a
bright (7/10) area over it's center. Aurorae Sinus appeared dark to dusky
(3-4/10) towards the following limb. The preceding (evening) and southern limb
appeared very bright (8/10). The following (morning) limb appeared very to
extremely bright (8-9/10).
04:15 U.T. ((CM 021.8*W,Wratten 80 (Blue)): The North Polar Cap (NPC) appeared
brilliant (10/10). Morning (preceding) limb haze appeared very bright (8/10).
Southern limb haze (SLH) appeared very bright (8/10). Morning (following) limb
haze (MLH) appeared very to extremely bright (8-9/10). Albedo features were
visible without much difficulty at this wavelength.
The best of luck to you,your family,and the members of ALPO Japan. I look
forward to your future images.

I have attached a belated RGB image of Mars from 7 February.
The NPC appears bisected by a dust streak, with dust covering its western edge.
Moderate violet clearing is again noted.
