Double Explosions on the Sun Today

The Sun had a fit and popped off two large events at once early today, Jan. 28, 2011. A filament on the left side became unstable and erupted, while an M-1 flare (mid-sized) and a coronal mass ejection on the right blasted into space. Neither event was headed towards Earth. This SDO movie, which is from Jan. 26-28, 2011, shows several other flashes and bursting from the active region on the right as well.

If you remember, in December, solar physicists released their findings that near-synchronous explosions in the solar atmosphere – sometimes millions of kilometers apart – can be related.

You can see another view of the events as seen by the SOHO spacecraft below, and another version of the SDO data.

Two major eruptions on the Sun occurred on Jan. 28,2011, and NASA's Solar Dynamics Observatory caught the action.

Here’s another multi-wavelength and closeup view of the events from SDO:

  1. I was out at an event for schools yesterday with a couple of PST’s showing people the Sun. I believe we were watching that eruption on the left side in these images and it was spectacular! In H-alpha light, you saw the long strand of plasma in front of the Sun then extend way off the edge giving it a very 3-D look. If you have an H-alpha scope, I hope you got to see it…every day should be that good for observing!

  2. Though I assume we have to be extra careful until the degree of correlation is worked out, “can be related” # “is related”. Patterns are mundane, meaningful patterns are sparser.

  3. hale-bopp: Are you satisfied with the performance of those PSTs? I’ve been interested in getting a beginner solar scope, and that one is certainly affordable (at least, comparatively so)! But I’ve been worried that something that (comparatively) cheap will just be a piece of garbage.

    Do you have any brief comments about the PST?
