Solar disk (January 29) imaged by Kos Coronaios.
Early in January, sunspot AR 1944 was a prominent feature on the solar surface and was widely observed – see the photos by Kos Coronaios.
Now, one solar rotation later, it is back. Now named Active Region 1967, it is an attractive sight.
Brett du Preez (Stellenbosch) observed it on January 29 and wrote: “Spectacular group, I’ve just had a look through binoculars. It seems as if there is more detail visible in this group than before. There is also a new sunspot [AR 1968] nearby.”
Image by Kos Coronaios using a Canon EOS 60D at prime focus of a 10-inch Schmidt-Newtonian reflector, with a 1.5x Barlow lens in place. Exposure settings were ISO 800 and 1/125-th second.
AR 1967 was responsible for a spectacular flare on January 28 – see this video on YouTube, for example.
