September 6th - H Alpha - Big Filament Still Dominant

[paulastro]

The large filament still dominates the disk in in HA, with AR2585 about as close to the CM as it will be.  At least 8 or 9 prominence scattered along the E and W limbs, with non being particularly significant.  Single frame with Lunt 60 DS, Olympus E-M10 at 500 asa, taken at 7.33 am on 1/60 sec.

Good catch Paul, there was a big prom eruption around the time you were imaging, you can see it on GONG.

Many thanks Dave.  The largest of the proms when I was observing was on the W limb, shaped rather like the crest of a wave - to my eyes at least.  If it was the one you're talking about I didn't notice it was erupting - though I didn't watch it for any length of time as I wanted to take some pics in white light afterwards.  Thanks for the tip-off I'll take a look at GONG - or go outside again while there is still some sunshine!

I've just had a look on GONG Dave and I'd come indoors before it started erupting - ah well, you can't have everything, nice to see it on GONG!

That filament is really sticking around!

Very nice Paul. Still no signs of blue sky here.

Nicely done Paul, that filament is quite something.

Thanks everyone.  I think the next couple of days will be better weather for many of us.

Well the forecasters have changed their minds, clouds here now.

Well done! Hope you are right, though as Dave says, they seem to predict sun 2 days in advance then cancel it on the day!  I was due to see friends and family today and tomorrow, but re-arranged it for yesterday to leave 2 days free for solar imaging, now I'm sitting alone under cloudy skies  .

That filament is certainly the star of the show. I have been trying to get the AR and filament together in a mosaic.

I hope the new arrangements worked out for you Iain!
