Another day with clear skies and average seeing for a change.  AR2734 has evolved a bit more and now is a Cro area with 7 spots and covers 30 millionths.  AR2734’s magnetic poles did not rotate and the small bipolar area that now should be close to the meridian, has disappeared.  This leaves one reverse polarized area in the Southern hemisphere, which can be seen in the CaK image.  Full disk images today with close ups of AR2734 in three wavelengths.
