Alas seeing conditions were poor, and frequent passing cloud a constant nuisance, nevertheless there were a few interesting features on the disk:
Illuminated Disk: Two dark streaks present on the disk, one in the far north (apart of the cusp collar?) and one a little further south towards the disk centre.
Unilluminated Disk: Not visible.Bright Limb Band: Visible and Complete.
Terminator: Geometrically regular- terminator particularly dark and noticeable today.
Cusp Caps: Both seem to have been present, but it may have been the case that the southern cusp was slightly more prominent.
Cusp Collars: Both Present.By 1644UT clouds had again returned and so it was not possible to do any filter work.
