Monster Explosion on the Sun (1st Feb, 2010)

    Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) observed a bright double-ringed coronal mass ejection (CME) billowing over the sun's western limb during the late hours of Feb. 1st. At present, the source of the blast is unknown.

    The bright object to the left of the Sun is Venus.

    Professor Koestler was right, we are doomed.

    Can this affect us in anyway? or has the chance of that been and gone?
    Im not really up to spec on what these are about (reading up on it now though :D)

    Pity the SDO hadn't launched yet,could have yielded some useful information.

    arghhhhh run for the bunker were doomed!!!!!! lol

    This is actually quite interesting. I think I heard somewhere that solar flares can affect climate change, not 100% on that though.

    I read that as 'Professor Kevster' and was thinking: What the frig?!

    That's one humongous prominence though.

    So when do the neutrinos start heating up the Earth's core (just saw 2012 the other day)?

    Seriously though, after such a quiet period with hardly any sun-spots over the past few months, this is quite an unusual occurrence, no?

    Or maybe our sun observatories (e.g. SOHO) are picking up a lot more CME's than they used to?


  • Registered Users Posts: 3,087 ✭✭✭Duiske


    Was just having a look over the past weeks Sunspot positions, and that CME seems to be coming from an area roughly where old sunspot 1041 should be now. It had degraded to virtually nothing when it went from view a few days back. Maybe its sparking to life again ?

    There was one seen by SOHO just after the Sept 11 attacks which was larger than this one, and was more directed towards Earth. Seemingly the auroras were amazing a few days later, but were not given any attention due to what was happening at the time.

    This is the clip from back then. Just at the end of the clip you can see the protons/neutrons hitting SOHO.

    Sun/sunspot activity does not in general affect anything on Earth except the Satellites that relay TV to us mortals!:)
    Sky sports could be forced off air!:eek:

    Seriously though this event seems to be way beyond the Suns usual activity(ten years on average for a flare or increased sunspot activity) to a large extent.certainly puts Astronauts to possible higher radiation levels than normal.

    The Sun is always a variable for Scientists trying to calculate best times for experiments.

    Is'nt the certain uncertainty sort of exciting though!:)

    Always in awe of this and the speeds at which the explosions travel outwards, fantastic stuff.

    Also can't help but notice the other objects travelling at speed that are caught on the timelapse.

    I think it was the sun's way of scaring the sh1t out of NASA. Imagine being days away from launching a new solar observatory only to have the sun in an inactive boring phase where little or no meaningful observations can be made. ;)
    At least now they can start looking forward to some interesting data.:)

    Lol Malty,lets face it NASA needed and deserved a break after the week they have had!:)
    the latest Solar observatry due for launch on Tuesday,lets hope it goes well,as things stand they would proably be happy to launch a firework!:).
    typing this from My bunker to avoid the radiation!:eek:

    just a picture i found that i liked of a previous Solar flare.
    WooHooo says the Sun,dont make Me angry You would'nt like me when i'm angry!

    I will now go and worship it,its scary

    The sun is coming to the end of its cycle so its possible its sparking into life as it comes nearer....was watching a Michio Kaku report on a possible huge solar flare coming up in 2011/12 which could knock out our satelittes etc...
    better start stocking up on books lol

    Hi.ya Digigal since the end of the world is now nigh any chance you will change your mind about us meeting up????:),i will even roleplay and pretend to be Your SON Sun :pac::pac::)

    You are right though best read the books we own now so we can burn them in My [EMAIL="bunker@Farenheit"]bunker@Farenheit[/EMAIL] 511:(

    If the 2012 theory is true We may as well just start a Global Party right now!:)

    Yayyyyyy lets go for it!!!!!!!

    A really nice sequence of shots from SOHO taken earlier today. Shows a CME, a comet heading for collision with the sun and the planet Mercury to the bottom right of the sun,

    In the above image; what is the long dark blue line?


  • Registered Users Posts: 3,087 ✭✭✭Duiske


    A massive CME recorded by NASA's Stereo Ahead, about 3am this morning.
