λ=209゚Ls,
(ω=112°W,
φ=21°S),
δ=15.7",
ι=39°
Seeing: 3 /10.
Note:
Caught a lull during the rainy days. The spc shows a rift whose eastern end is quite dark. The hook made by Phasis and Phienics L is consipicuous. The Araxes complex is also evident. Arsia Mons is near the CM, while its LMT is about 2:40 PM (since ι =39°), and looks slightly misty. Olympus Mons is barely seen in R. Notable is the white matter on the morning limb at Electris/Eridania.
Instrument:
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).
