Sunspot 2529 visible with safe viewing techniques

Heart-shaped Sunspot 2529 imaged Sunday 17 April at 4:30 pm from Largs North, Adelaide. Canon IXUS at 400 ASA , 1/100 of a second exposure, infinity to infinity focus with a 4" Newtonian and 25 mm eyepiece and neutral density solat filter.

The sunspot is the large dark spot (click to embiggen) and the other dark stuff is junk on the CCD chip.

Sunspot 2529 is big enough to be visible with use safe solar viewing techniques. It will rotate off the sun in a the next two days, but is worthwhile looking at.
