(ω=073°W - 089°W,
φ=14°S),
δ=8.4",
ι=42°
Seeing: 4/10.
Note:
Solis L is dark detected, distinguished from Agathodaemon on its east side and a dark area around Aonius S on its SW side. The latter area looks to be affected by an atmospheric mist. Chryse is also a bit misty. Nilokeras remains still inside. The Tharsis ridges appears dark as a segment, as already detected on 11 March at λ=151゚Ls.
In B, the sph is large and dense, maybe shows some naked spc. The B image suggests a blue clearing, but it is possible the longer waves are not well blocked or a large misty matter stays on the lighter parts of spheres.
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).
