Hail, fellow suntards. Great work IWTB on the videos. I don't mean to nitpick but the lonely C1.2 flare was from 1376 to the north. [link to www.lmsal.com]
We should see more flaring soon as more active regions are popping up in the southern hemisphere and two more in the north should be rising over the limb in the next day or three. The region coming over the southeast limb (seen near that prominence in the video) looks to be producing some flares.

More research and analysis needs to be done on the sun's strange zig-zag effect on the comet's tail.
:EUVI_B:

As noted on the Sungrazer update page, this behavior is still unexplained--

"This one is a short animation of four frames from the STEREO-B EUVI instrument at the 171-angstrom wavelength (corresponding to about 1.5million degrees, I believe). The comet is clearly visible racing away from the Sun, leaving a wiggly-tail in its wake! Why the wiggles? We're not sure -- we need to start studying that when we get all of the spacecraft data from STEREO-B this weekend. However, we think there may some kind of helical motion going on, or perhaps there's a projection affect and we're seeing tail material magnetically "clinging" to coronal loops and moving with them. There are other possibilities too, though, and we will certainly investigate those! We should have equivalent images from the STEREO-A spacecraft which we will also get this weekend. When we pair these together, and throw in the SDO images too, we should be able to get an incredibly unique 3-D picture of how this comet is reacting the the intense coronal heat and magnetic loops. We really are going to learn a lot here."

Hi, Shenuee & aether!
