Active areas 907 and 909 were both still visible with two small, faint spots each. Active area 908 (the return of active area 904) was also still visible and appeared to look much the same as yesterday with a large umbra and a smaller umbra both sharing a common penumbra. |

I watched the display for almost half an hour, it was constantly changing as the cloud moved on. |
