Please find attached a drawing I made of Venus yesterday afternoon. Seeing was in general rather poor- around AIV-V for most of the time. Still,there was a very interesting dark streak on the disk and what appeared to be a large bright region in the north. Other notes include:
Illuminated Disk: Vague dusky features in the south,a rather dark streak present in the north just above a large bright region extending over the northern pole. The attached drawing is a reasonable representation,of course the poor seeing means that there could well be errors.
Unilluminated Disk: Not visible
Bright Limb Band: Visible and complete
Terminator: Geometrically regular.
Cusp Regions: Either the northern cap is ow very large,or else it is its usual size with a diffuse bright region nearby,but the poor seeing is making it look like all of this region is very bright. The southern cap can be glimpsed. Neither cusp collars observed.
