Observation of Venus made this evening.  The seeing was fairly good at times (although predominantly AIII-IV), but during the stable moments, some subtle features were seen.  The southern cusp collar continues to be the darkest feature on the disk.  Also present:
  • Bright Limb Band: Visible and complete (dazzling at times)- bright patch visible on the limb just north of the equator?
  • Terminator: Geometrically regular
  • Cusp Caps: southern cusp cap seen, still no real sign of the northern cusp.
  • Cusp collars: only the southern one present, and quite dark.
I had hoped to attempt filter work, but the clouds came up at 1615UT putting a stop to observations.
Best wishes,
