The Sun in White Light
The sun today in white light. Single exposure, ETX 90 with solar filter. The leftmost spot is 1312; the spot to the right and below it is 1313. Further to the right and above is the small spot 1311. Faint, small spot on the right limb is 1305. The group of real interest is almost directly above 1312. It is group 1313 and it is crackling with C class flares.
