A spectacular view of an active region this morning - the intense white storm imaged on March 8 (link below) has evolved into a great tear across the SEB between the GRS and STrD. The jetstreams either side of the SEB can clearly be seen by the distribution of white material from this storm (or maybe now 2 storms?)
Close comparison of the p. and f. white streams shows some interesting colour distributions - the white centre is edged in red on the polar side and blue on the equatorial side in the portion that precedes the central storms (ie away from the grs), with the colours reversed on the following segment that's being pulled into the grs. At first I thought my colour alignment was wrong, but this effect is symmetric across both the preceding and following segments in a way that cannot be corrected by lateral alignment so I guess it must be real although I have no idea of the cause - maybe altitude and/or velocity related?
The Equatorial zone is also fascinating, filled with what looks like high blue cirrus :-)
This was the only image possible from this mornings session, the seeing was particularly poor for the rest of the time with only a short break of reasonable seeing for this capture about 30 minutes before sunrise.
A frustrating session this morning, a lot of high cirrus cloud dropped transparency by at least 50%, limiting me to around 25fps max in all channels.
Here is one image from early in the session, with luck I will have another image to post later from late in the session, around 1915Z. I may also refine this image when I get a chance to remove the registax alignment artifacts around the edge. Jupiter was still very low in altitude at the time of this image.
The orange colour in the new "lrs" is very intense!
