Ha Full Disk - 11th November

It's been a while with one thing or another since I last managed to get some solar observing in, however Sunday afternoon offered some low altitude sun to look at.  While the disk is at first sight comparatively quiet it indeed tells a story; the small emerging flux region mid disk is the last relics of cycle 24 throwing out magnetic flux, however the northern polar crown marks the boundary of the northern jet stream where cycle 25 will kick off, and near the limb on the right hand side it is possible to see the remnants of a small spot with reversed polarity, typifying it to be the next solar cycle.  The shots were taken with double stacked Lunt 50 etalons and the PGR Chameleon 3 camera.  The proms below looked great visually in single stack mode.
