The Sunspot AR2833 was recorded on 06/18/2021 at 1:40 PM ET. You will notice the faculae all around AR2833 and on the suns disk. The Umbra & Penumbra are also visible in AR2833.

The activity has been recorded on Spaceweather.com as AR2824, after being on the far side of the sun, and now has been renumbered to AR2833.

The image was captured using a Daystar Quark Calcium H-Line filter, at 3968.5A (angstrom). The solar scope used was a Lunt 80mm MT APO refractor and Altair 174M Hypercam monochrome, fan cooled camera using 136, recorded SER images.
