Photo of the Week for April 29, 2016

Even as solar activity slowly declines, the Sun occasionally puts on a show. On March 13, 2016, a large, circular prominence appeared and was recorded by NASA’s Solar Dynamics Observatory — and with equipment decidedly less modest than what was used to create this image by Sylvain Lavoie from his home in Longueuil (near Montreal), Quebec. The prominence shows nicely near the one o’clock position.

Sylvain captured the Sun with an Imaging Source DMK41 CCD camera mounted on his Lunt Solar Systems 60mm double-stacked, Hydrogen-alpha solar telescope.
