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.

here are images of Venus from last evening through both UV (325-375nm) and IR (1000-1020nm) filters.
I'm using eyepiece projection for the approx 5.5x focal length extension with a Kokusai Kohki Circle-T 12.5mm Abbe orthoscopic eyepiece.
This is giving me approximately 2x the UV signal compared to my previous arrangement that used a Televue 5x Powermate.
