Unfortunatey, it looks like SOHO missed most of the event.

I wasn't sure what I was going to write about today; that'll do nicely! Thanks for keeping an eye on the Sun for the rest of us, Sunspot! I would love to see SDO images of this; I don't yet have a good sense for what SDO will be showing us.

Im soooo hoping SDO caught this... can you imagine it not in a 1024x1024 pixel image like SOHO but one at 4096x4096 and images every 10 seconds

Made a animated GIF from the C2 images

SDO started a calibration maneuver at 8:00UTC during this event, in which it turned away from the Sun. During the maneuver it would have briefly glanced at the Sun again. This was after the EIT image mentioned above, but before the coronagraph images. I can't say anything about whether AIA was taking pictures before 8:00, just what the spacecraft as a whole was doing. If they were taking pictures before this maneuver or during the part where the spacecraft glanced back, they should have something (additional) awesome to show at the first light press conference.

It's not like this is the last flare expected to occur during SDO's lifetime. There will be dozens, hundreds, thousands over the next decade.

Direct link for the LASCO C2 movie of the recent mass ejection

(interesting to see something apparently flying splat into the Sun on 10 Apr - I assume this has been discussed elsewhere)

Word is the SDO press conference on the 21st will have video of at least one prominence, but it's not necessarily either seen here. As Doug said, there will be lots to see over the years.

Comet Eaten By the Sun As Spacecraft Watches

Not so rare an event it seems. From 2006: Comet Plunges into the Sun

No, not at all. IIRC, SOHO's picked up more than 1700 Sun-grazing comets, many of which actually impacted the Sun.

Relatively bright ones like this are uncommon, though, and definitely very cool! smile.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

All this activity is really making me want to buy a solar telescope... Had a look through a few, and seeing prominences in an eyepiece is absolutely amazing. I think that once SDO starts releasing images, and video, of the Sun "in action" demand for solar telescopes is going to go through the roof...

I feel some overtime coming on...

Yes, but the Sun has been blank and lifeless for about 700 days over the last few years, this is like Christmas coming.
