    This afternoon (@ 2:15 pm to 2:50 pm) I was looking at the
    Sun with my Day Star T Scanner (H-Alpha) about 0.6 a.

    There were several large prominences. In my field of view
    the image is reversed left to right. On the lower right edge,
    about 4 o'clock, there was a large, thick loop and what looked
    like a prominence near but not yet at the limb. It was a long grayish
    area that looked to be above the H-alpha surface. I was wondering
    if this was a prominence seen from above rather than in profile?

    There were dark markings on the surface. The surface looked
    very bumpy. The sunspots could be seen along with very bright
    areas near the large sunspot groups. There were also some bright
    areas away from the sunspot groups. One of these light areas was
    like a ">". A little to the right of the large sunspot group in the lower
    middle of the Suns disc there was a long thin black line. I made a
    sketch but need to clean it up a little. My hand drawn circle wasn't
    very round.

    The Sun was also very interesting in white light.

    Telescope: Takahashi FC100 (100 mm f/8) fluorite doublet refractor
    Filter: Daystar 0.6 a T Scanner, 4" prefilter, 35 mm eyepiece, barlow,
    telecentric lens, Maxbright diagonal, etc. I believe the image was at
    about 50x.
