    Default Recent Solar Activity?



    How are things on the Sun of late? I see one posting about prominences a few
    days ago. The Big Bear site shows nothing much in the last seven days; however,
    that site shows a few sun spots. Some good radio activity was posted on the SARA
    list a few days ago.

    Anyone active on the alt.astronomy.solar NG? I haven't looked at it for over a
    year, but looked again today. It has it's usual clutter of off topic postings.
    Too bad that someone cannot police it a little better.

    I observed the Sun on Sunday. There was a large arch (probably about
    25 percent of the Sun's width) on the northern half of the Sun, toward
    the following limb. It was seen as a filament, since all of it was
    against the solar disc. In the same direction, on the limb, there was
    a small, elephant-shaped prominence, a few Earth widths tall; the trunk
    faced clockwise in the mirror-reversed view. Directly on the opposite
    limb, there was a smaller, triangular shaped prominence, maybe three or
    four Earth widths tall. (An Earth width is around 1 percent of the
    solar width, by the way.)

    There were a few major sunspot groups. There was one sunspot close to
    the large filament, and another pair of large sunspot groups clockwise
    from that one (again in the mirror-reversed view). There was a smaller
    double sunspot south of the center of the disc, with the smaller sunspot
    of the pair to the north of the larger. This is going from memory since
    I just observed casually. Would people like it if I posted prominence
    reports when I note them? It might make me take better notes.

    Actually, considering where we are in the sunspot cycle, the sun is
    fairly active, although nothing like what we saw near sunspot maximum.
    Today it looked pretty good, with five active regions and two
    spectacular quiescent prominences on the west limb. Two of these active
    regions have rather complex structure and may be prone to a little more
    flare activity. Several fine loop prominences showed on the eastern
    limb late this afternoon indicating some activity coming around.
    Several filaments were easily seen on the disk, so all in all, the sun
    is worth watching (at least in H-alpha). Clear skies to you.

    What!? On-topic posting!? Are you mad? Have you been out in the noon-day
    sun, looking for prominences?

    By all means, post them.
