New monster active region AR11734 rotated into view on the 28th april, the region has a huge umbral area compared to other active regions on the disk and could well easily become a naked eye spot in the days ahead. It also harbours energy for M-class flares. This image was taken with the 70mm PST mod at 1000mm fl with a DMK31 camera.
