NASA's SOHO Captures Halo CME August 7th [HD Video]

Newer Older

NASA image acquired August 7, 2010

SOHO captured this video clip of a full halo coronal mass ejection (CME) that blasted a substantial cloud of particles away from the Sun (Aug, 7, 2010). The majority of the cloud went to the left with only a smaller portion heading to the right, suggesting that it would not likely have any strong impact on Earth. A “halo” cloud is one that appears to surround the Sun on all sides as it expands, meaning it is heading somewhat towards Earth or away from it. The still and movie are generated by processing the changes from one frame to the next to highlight those changes, thus, we call this a “difference movie.”

    No kidding, Wow
    The sun is pretty big,,and that explosion was even bigger ;p

    What is the time-scale being shown here? That is, at what frame rate is SOHO capturing images (f per sec, per min, per hour...) ?

    Awesome stuff, regardless. Thanks so much for consistently sharing so much incredible imagery from all of these missions/instruments.

    Whoa. That was impressive.

    Way to go. Nice job. Amazing solar activity. Keep those satellites working!

    @aranovich - This is showing an image captured every 12 minutes for about 16 hours.

    Thanks for following our photostream, we have some amazing things going on here at NASA Goddard!

    more CME's!!! Is our equipment able to detect this activity on other stars?

    difference movie? is that the same as compressed imagery?

    felt like a ship landing on the moon at first. great

    @ NASA Goddard

    Thanks for that info. I'm still trying to wrap my head around the incredible velocity and sheer scale of the ejection(s).

    In particular, the ejection which begins at 18:24 and expands to roughly 4x the diameter of the sun in only 1 hour 12 minutes!

    That's... 4(1.4 million km) / 1.2 hr = 4.67 million km/h = 77,833 km/min = 1297 km/sec ... FAST!

    Are these crude estimates of mine sound?

    Lastly, are there any estimates of the total volume of the ejection(s) in this video?

    Thanks again!
