Photo of the Week for September 15, 2017
Despite solar minimum lying just a few years off, the Sun was very active in early September. It sported several large sunspot complexes, generated auroral displays and even kicked out a powerful X-class flare on the 6th. Designated AR12673, the sunspot group responsible for the flare is positioned on the Sun’s limb and sprouting a double-loop prominence in this H-alpha image.
This striking photo was captured by Sherbrooke, Quebec, imager Daniel Brousseau on September 10, 2017. Daniel used a Sky-Watcher 120ED refractor telescope, ZWO ASI174 monochrome imaging camera and Daystar Instruments QUARK H-alpha filter “eyepiece” (chromosphere model).
