Is this a solar flare?

[Kaptain Klevtsov]

Grabbed this today with the PST

I had to do three layers, one short exposure to get the disk detail, a second longer exposure for the sticky out bit and then a third layer to add colour.

I dont think so, i think it's just a prom. Flare are HUGE if i understand it right, like about the same size as the diameter of the sun. Could be wrong though, Astroman?

Great image though!

It's a prominence that looks like it originates over the limb.

"Solar Flares" are generally not visible in the visual range. They tend to be x-ray events that may or may not be associated with a "white light flare" that you can see. Flares travel at the speed of light, while prominences and coronal mass ejections travel at supersonic speeds. Flares arrive at Earth 8 minutes after the event, CME's take a couple/three days. A flare's size is mostly irrelevant, it's the amount of energy you need to be aware of. They can be "small", (on the scale of the Sun, what's "small"?), and very energetic or vice versa, and any combination in between.

Im pretty sure you could light a cigar with that prominence.

Right, Jamie. You could probably light a cigar ON MERCURY with that prominence. :shock:

Actually it was mostly aimed at P&S cameras with not much about webcams, nevertheless a very interesting read.

Pic similar to yours on SW CC, Thats a prom according to them.

Ace pic though, might have to get some film and point my scope to the sun.

You can put as much Baader film on as you like, but things like this will not show up. Has to be very narrow band to show up the bonfires that they have on the sun.

"Bonfires" is an interesting analogy, CC. Rough estimate of 40,000 MILE high flames! Think of the particulates! :sunny:

Sounds like one of my fry up specials on a sunday morning

OOOPAAHH!

40,000 miles? They'd have it put out in no time round here. Can't even burn a few cars pallets without the fire bobbies turn up.
