Details:
Consecutive day #17. Attempting to get a complete
revolution of surface features hoping for the return of sunspot AR2665. The Sun revolves at about once every 25 days at its equator and up to 30 days near its poles. Taken with a double stacked Lunt 60mm with a B1200 blocking filter all on a stationary tripod (1/250 second ISO-200).
