Initial impression was a bit of disappointment because the huge
prominence that others are reporting wasn’t apparent to me at the
eyepiece. Later today, that large prominence was reported to have
dissipated by 1600UT, so I believe I had just caught the tail end of
it. It was to the northwest and at 1615UT, all that I could see in that
area with our poor transparency was a faint wisp of a prominence.

There were three areas of plage; one nearly midway across the disk and a
second one to the east, both in the northern hemisphere; and another
small area ~ 150° just inside the southern limb. This southern one
makes me wonder if it could be an ephemeral region. Three fairly
obvious filaments could be seen, the largest nearly reaching the small
prominence at ~190°. The center of the disk was full of the dark
hairlike fractures of fibrils or spicules, making a beautiful scene when
moments of better sky conditions would allow for it.

  1. Erika,

    This is a beautiful solar sketch. Huge prominences wait for nobody. It boggles the mind how fast the solar scene can change.

    Frank 🙂
