The Sun 6-7-2013

It might be a rather warm 23 degrees outside but there’s a lot of cloud around too and the atmosphere is very turbulent, so there was no opportunity for some nice close up images of the large sunspot groups 1785, 1787, 1788. The smaller 1784 group can be seen to the right. The largest sunspot, 1785, has the potential to produce some big flares as it turns to face earth.

This set of images were taken between 12.00-13.00 UTC using the Coronado PST/Coronado CaK/Lunt CaK B1200 on a Vixen 115s. IS DMK41AU02 USB mono video camera. Images processed in Registax 6, Adobe Photoshop Elements 9 and Adobe Lightroom 4.4
