The sun is currently fairly blemish-free, except for one group of three rather large individual spots. There's another group that will be rotating into view soon, you can just see it on the solar limb. I'm going to hurry and get out the PST before "Hell's Kitchen" and "Master Chef" come on. May have to abandon the "Big Bang Theory" re-run, lol. I've seen it already. But Gordon Ramsay is my preferred summer TV entertainment, par excellence. "Donkey!" lol. I dream of Beef Wellington...drool...but promises of prominences await... Just before the Venus transit, I replaced the Baader film on my home-made 50mm solar refractor. The film lasted some 12 years, and the biggest reason I replaced it was dust, not pinholes. Had I been more careful in my storage practices, the first film installation would still be in-use. Glad it's only a 50mm aperture and my big sheet of film didn't take much of a hit. I own several glass solar filters, by different manufacturers, including TO and Celestron. I used none of them for the eclipse or the transit. Baader film consistently gives the best visual views, IMHO. More detail, better contrast, and no fakey orange, green, or blue tints. The tints just reduce the contrast.
The spot rotating into view had a beautiful arch prominence over it yesterday. At least I am hoping that is the one. On Mon, Jun 18, 2012 at 6:39 PM, Chuck Hards <chuck.hards@gmail.com> wrote:

The cloud breaks aren't coinciding with the commercial breaks, lol. I'm siding with the AC. Prominences last for minutes only. Something new is constantly being brewed-up by old Sol. Keep watching! The rarest of all treats is the white-light flare. No H-a scope needed, but again, it lasts only minutes, at most.
BTW, the first solar flares to be observed by humans were seen via projection. No filters of any kind needed.
Wasn't that the case for the Carrington event in 1859? Seems like I heard that he (Richard Carrington) saw the flare that produced the solar storm using white light projection. patrick On 18 Jun 2012, at 19:52 , Chuck Hards wrote:

Prominences may change appearence over minutes but they can last for hours. On Mon, Jun 18, 2012 at 9:12 PM, Patrick <paw@wirelessbeehive.com> wrote:

Very true, although this solar max has been a rather wimpy one. I can't remember seeing a prominence that truly lasted more than a half hour, this time around. On Mon, Jun 18, 2012 at 11:29 PM, Siegfried Jachmann <siegfried@jachmann.org

prominences and flares are 2 different things, flares can be seen in white light.

I know you know, I have never been to a solar party that someone does not refer to a prominence as a flare.
I know. We were discussing both.

OK, I'm embarassed. The triple grouping is still visible, but it is rotating out of view, and there isn't anything else visible in white light coming around on the eastern limb. I had forgotten that I had replaced my regular diagonal with an erecting diagonal for some birdwatching of my outdoor feeding station. I had thought I was seeing a reversed image when in fact it was correct. I may try and steal a peak through the PST if I get my yardwork done before the sun gets too low today. Another working weekend ahead so I have to get the chores done after work on the weekdays. I'm getting too old for this nonstop work crap.
I couldn't resist. I took out the PST right away. Disappointment. The only prominences visible are a few small "spikes", associated with the sunspot group that has already rotated out-of-view. A pretty boring sun for this close to solar max. The good news is, clear skies are predicted to be the norm for the next few days. Anything can sprout on the advancing solar limb, at any time. I may take the PST to work with me this weekend, for periodic sanity breaks.
There is now a small, semi-arched prominence visible at about the 7-o'clock position, not associated with the triple sunspot group. Still a few small "spikes" visible associated with the group. Time about 5:45 PM MDT. Sorry, Patrick. I know UT is more professional, but we have a wider audience.

Very true, Patrick. Here's a brief write-up of the event that mentions Carrington's use of projection: http://www.noaa.gov/features/02_monitoring/1859solarstorm.html On Mon, Jun 18, 2012 at 9:12 PM, Patrick <paw@wirelessbeehive.com> wrote:
