Details:
Active Region (AR) 4142. With gamma and possibly delta classificator, it's quite active, basically one of those regions which emits light continuously. That morning the Sun X-ray flux was approximately steady at C1 level. But overall, this is a rare example of AR exactly on equator, with sunspots in both hemispheres: Welcome to the center of the Solar cycle. Lunt60 H-alpha + Neptune-M, SharpCap; Autostakkert!, ImPPG, Photoshop. False color.
