Description

Well, in the absence of adequate conditions for new images, here goes still another processing and animation, showing the ongoing long standing NNTZ/NNTB "storm" system - if indeed is it what it is.

Celestron SCT 11", f/30, ASI174MM, Astronomik IR685nm filter.

7 frames, from 04:00 to 04:49, in 2015 05 20. Each frame is a WinJupos derotation of two adjoined 60 second captures.

The first three frames show the feature entering the disc with fair visibility, the seeing worsened later, giving poor subsequent frames, which still show the feature, just blurred. Maybe another dark spots appear, but the noise makes it difficult to be positive.
