Well it's looking cloudy in the south. But it's a very nice temp. Maybe it will clear off. Mark Sent from my iPhone
What about Friday night? I may be up to some observing but have a minor back issue. Let me know. Deb On Mon, Mar 25, 2013 at 8:25 PM, Mark Shelton <astroshelton@yahoo.com>wrote:

Hi, the clouds parted today and I had a chance to get out the Coronado. There was lots of activity this afternoon. Lots ofCME to look at, all around the sun. My brother/sister in-law had a great experience looking through the double stack. Weather is looking better for Friday and Saturday. Friday afternoon I will be at.........town and country bank with the solar scope. 1-3 or so. Things are looking up here in st. George.

May swing by there tomorrow to see that. On Thu, Mar 28, 2013 at 4:33 PM, Mark Shelton <astroshelton@yahoo.com>wrote:

Just a minor point, Mark, but prominences are not CMEs. CMEs, prominences, and flares are often confused and the terms used interchagably but incorrectly. Coronal Mass Ejection (CME) A major solar event in which a large amount of coronal mass (as much as 10^16 grams) is ejected from the sun at speed of tens of km/sec up to 1000 km/sec. CME's are thought to occur with a frequency of one per day. CMEs are an outflow of plasma from or through the solar corona. They are often, but not always, associated with erupting prominences, disappearing solar filaments, and/or flares. CMEs vary widely in structure, density, and velocity. Prominence A term identifying cloud-like features in the solar atmosphere. The features appear as bright structures in the corona above the solar limb and as dark filaments when seen projected against the solar disk. These dark filaments are also called flocculi (plural of flocculus). Flare A solar flare is a sudden brightening observed over the sun's surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules. The do not necessarily occur in visible light. CMEs typically follow a flare. All of these are associated with active regions on the sun, which are manifestations of magnetic field activity. Glad you're having fun with the solar scope! When showing the sun to the public, I like to have a white-light view at the same image scale next to the H-a scope, for comparison. Sunspots are usually easier for people to see in white light, since they are not competing with all the other surface detail visible in H-a.

Thanks Chuck, I have lots to learn. But having lots if fun doing it. This will be my first season with the coronado, and there was lots of activity on the sun today. I think I can safely say that. I think activity could cover a lot of things LOL. Mark Sent from my iPhone On Mar 28, 2013, at 6:36 PM, Chuck Hards <chuck.hards@gmail.com> wrote:

Mark, having fun is the single most important part! Were you at the last SLAS meeting? The speaker is a solar astronomer and his presentation was incredibly educational. I thought I understood the dynamics of solar phenomenon, man was I ever wrong. Thanks to him, I now have a good working grasp of what I'm seeing when I look at the sun. Makes the activity a lot more interesting. That meeting alone made the cost of a SLAS membership money well-spent. On Thu, Mar 28, 2013 at 9:58 PM, Mark Shelton <astroshelton@yahoo.com>wrote:

Hi, no we did not make the last meeting . My wife was not up to coming and I was not either. We really wanted to come but it did not happen. Mark Sent from my iPhone On Mar 29, 2013, at 7:35 AM, Chuck Hards <chuck.hards@gmail.com> wrote:

Bummer. I've had the thought of shooting video of SLAS meetings and selected events (I know others have, as well). The club would have to invest in storage for the files, but then they would be available to all members and would be a nice resource and historical record. Off the top of my head, it would probably amount to a terabyte every two to three years, depending on the video resolution. They could also be burned to a DVD library after a year or two so only one dedicated hard drive would be needed. On Fri, Mar 29, 2013 at 8:02 AM, Mark Shelton <astroshelton@yahoo.com>wrote:

I would be uncomfortable with that level of scrutiny. Every time someone made a joke or asked a dumb question, it would be recorded. I prefer not to do video on a regular basis, but to keep our club casual. If we have a notable speaker from out-of-town, who would be getting a fee of some kind, that might be worth recording -- if the speaker agrees. But otherwise I'm sure many of us would feel a dramatic chill fall across our spontaneity.

I certainly understand that point-of-view, Joe. It also requires a level of committment that may be hard to stick with in the long run. Although that solar lecture would have been a very good one to archive. How would you feel if someone recorded a meeting on their own, with the speaker's permission? Is SLAS permission needed?

It sounds a little like Joe thinks SLAS meetings are a court of law, I doubt recording changes anything. It has been discussed before, buying the equipment etc..... but never gets off the ground. They're have been meetings worth recording. Recording would leave little doubt about intellectual property.
