The situation from Mare Cimmerium( 230W,-20） to near Solis lacus (90W,-25) 
was recorded. By Mr. Christophe Pellier's picture, spot bright on
right-hand side is seen. Although it is remarkable by a red picture,
true character does not clarify. (reported by 2 observers)
FROM Makoto Adachi
-------------------------------------------------------------------------------------

I was able to make my first observation of Mars on July 20,2009  (10:15 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain.
I was  excited to observe the red planet once again after the last  opposition. I hope to follow Mars as much as possible.

Notes:
The South Polar Region (SPR) appears to be obscured by a very bright  to extremely bright (8-9/10) haze. Mare Cimmerium appears dark to
dusky (3-4/10) towards the south-preceding (Sp) limb. Electris,Eridania,and Ausonia appear dusky to bright (4-7/10). Zephyria,
Aeolis,and Aethiopis appear bright (7/10). Amazonis and Arcadia  appear mottled and dusky to shaded (4-6/10). Elysium,Aetheria,Libya,
Cebrenia,and Panchaia appear bright (7/10). Syrtis Major appears as a  thin,dusky (4/10) streak along the following limb and partially
obscured by a very bright to extremely bright (8-9/10) morning limb  haze (MLH). The North Polar Cap (NPC) appears brilliant (10/10) along
the northern limb.

I was unable to make an observation of Mars using a blue (Wratten 38A)  due to excessive sky lighting.
