Wow. Is that a flare at ~ 50s in? Amazing.

HI Sean,
I just thought the last days: Are there any new videos from the SDO probe? :-)
Thanks for this videos, they are really fantastic!

My hint: Just look at this video in slow motion (1/4 speed)!

Good timing & thanks!

I'm working on a long form 'filament' clip which is very pretty to look at!

Have noticed an anomaly in the Solar Dynamics Observatory daily intensitygram images, for the past four days. On the righthand side of the images there is an odd, diagonal line across the solar disk, which is lighter in color than the surrounding surface of the Sun.
I suspected this was a transitory fault, perhaps caused by the intrusion of an energetic particle into the camera. This seems unlikely, though, after three, day-after-day repetitions, in the very same position against the solar disk. It also seems unlikely that an imaging processing artifact would persist like this, without correction, or even comment. Any ideas on what could be causing this anomaly?

It's pretty obvious in the thumbnail visible at http://spaceweather.com/ The Gong H-alpha monitoring network doesn't show anything there. http://halpha.nso.edu/

It's been two weeks, now, since the anomaly was discovered in SDO images. It's still visible in today's daily intensitygram images. The Joint Science Operations Center, at Stanford, has had, and still has an advisory, in red, at the top of their webpage. They admit that that the anomaly can not be removed by image processing, and that they can not explain the source or cause of the anomaly.

Please find a link to the JSOC website, below:

I'm honestly not seeing this artifact, can someone post an actual image that shows it?

The tone of some of these messages is flirting with rule 2.6 IMHO.

Here's a clip off of Spaceweather with the artifact highlighted. It's a diagonal strip across the disk.
