Attached are four drawings of Venus I made yesterday afternoon. Seeing was not terrible good but a number of features were visible on the disk. The planet was viewed in IL,and with W11,W25A and W47 filters. In IL,dichotomy appears to be very nearby and the phase seemed to be about 51% (although seeing was poor so it was hard to be certain). Dichotomy seems to have passed when viewed with the W47- the phase in this filter seems to be about 49%.
Illuminated Disk: General hue of disk present- some vague streaks seem to be present but nothing definite.
Unilluminated Disk: Not seen.Bright Limb Band: Visible and Complete.Terminator: Geometrically Regular.
Cusp Caps: Both seem to be present and about the same sort of size and brightness.Cusp Collars: A little harder to see,but both seem to be present.
1454UT (W11): The phase in this filter seems to be about 53%. South polar cap *may* have been a little more prominent.
1459UT (W25A): There seems to be hardly any markings on the disk at all in this filter- just the general hue of the disk. Phase similar to IL and about 51%.
1504UT (W47): Dichotomy seems to have passed in this filter- phase looks to be about 48-49%. Darker markings are much easier to see.

here are my Venus obs under average conditions in narrowband IR ~900nm separated by about an hour . The 2nd obs is not that clear cause of the planet altitude.
