⇧ Sunspot region 2645 magnetogram and in visible light as seen by SDO. Delta spot indicated.

We admit that this delta sunspot is still small as it has only recently formed in the past few hours but it is fairly compact close to the larger negative polarity (red) sunspot umbra and that is good news. There is some rapid flux emergence going on in the intermediate layout of sunspot region 2645 which is a nice sign that this sunspot region is still very much in a phase of growth without much decay. Its too early to start promising strong solar flares but should this sudden growth continue it wont take long before we start seeing C-class solar flares again and even an M-class solar flare should not be excluded!

Worth to keep an eye on this sunspot region to see if it continues to develop and of course on the solar X-ray data today. Should there be a significant solar flare we will of course keep you up to date. Nice to finally have a sunspot region on the disk with potential after months of pretty much no sunspot activity!
