AR12141 - New Active Region in CaK - 14th August
New active region AR12141 (closest to the limb) and it's counterpart AR12139 (mid image) were both very bright in CaK wavelengths with lots of bright plage. A peppering of small spots in both active regions suggests they may well be a bit more active than AR12135 currently departing on the western limb. The image was taken with the 40mm scope at 925mm focal length with the DMK31 camera.
