望遠鏡をNewtonian20ｃｍＦ6からシュミカセC11変えて撮ってみました。光量アップしましたが解像度はあまり変わらないようです。

Seeing was in general poor and so I restricted filter observations to W15 (yellow) and W21 (orange). Two dusky cloud bands could be made out and the region between the two seemed brighter. Also:
Bright Limb Band: Visible and complete
Terminator: Geometrically regular
Cusp Caps: Both equal in size and brilliance,both seem to be rather bright.
Cusp Collars: Both seen,southern cusp collar may have been marginally darker and easier to see.

In poor weather conditions with wind and clouds. I managed to capture some interesting data though. The Cloud Discontinuity is faintly visible in the IR900nm image. Moreover a bright area follows the dark CD vertical streak which is rather usual:

CD visible.

CD was visible in IR,and a partially overlapping (dark) pattern was seen in UV (see UV-IR685 gif; 19:11 and 19:14UT).
I confirm Manos report of brighter cloud at the CD.
Pending processing image data from April 30,May 1,2,and 4.
