Row of sunspots Dec 18th
Dec 18th. A nice row of sunspot groups in the Sun's southern hemisphere.
A number of active regions could be seen. These two pics are single exposures taken thru a WO 81 mm refractor with herschel wedge at 540 nm and Canon 550d camera. Taken in very hot conditions (38°C) at 0.47 UT (around noon local time). Thanks for viewing.
