October 8, 2013: Two big proms and a curious linear filament

[michael.h.f.wilkinson]

Just had a look at the sun with my H-alpha scope through the haze. A very large, thin prom is visible northwards on the eastern limb. The structure is nearly linear with several knots. Nearby on the surface a long filament can be seen. This is nothing special in itself, but this one is straight as a poker. Really curious. I first thought it was part of a con-trail, but it moves with the sun.

Finally, there is a huge arcing prom way south on the eastern limb.

Cheered me up no end on a day when I am at home suffering from sinusitis. Solar observing can be very therapeutic.

Just had another look, and the northern of the two proms is more complex than I first thought. As the haze thinned, an almost A-frame like shape was apparent. There is a distinct, branching knot at the top of this "A-frame".

Update: the knot in the northern prom now seems to have detached. It almost looks like a puff of smoke.

The brief view I had yesterday were pretty spectacular...  just gutted I didn't manage to get any images but this is the observing section

After rushing home and setting the scope up I had no more than 10 mins unobstructed viewing before it headed for the trees so it looks like my home based Solar is coming to an end until next year...
