Seeing: 2-3 /10.
A lull permitted to take an image of the dust cloud in Noachis. Compared with ISHADOH's photo on 4 July, the eastern part of S Sabaeus clearly recovered. The dust cloud is also newly defined quite differently from the one on 4 July. There is another cloud in Deucalionis R, and both look to be connected in water vapour component as seen in B.
Use is made of an f /7.7 Newtonian extended to f /50 having a 25 cm speculum equipped with an ST-5C (at -5ﾟC).
