Huge comet seen on soho web page.

  1. Dec 14, 2009 #1
    This new comet is a sun grazer, remember comet neat in 2003? It was is almost 2 times the size of jupiter..

    This one may be bigger, but there is no comet tail, why?
    More about this when it gets closer to the sun, 2 or 3 days?

    How do you know that's a comet and not, say, Venus?

    I see no entry for that picture on that link. Could you copy and paste the entry in that log you think applies?
    Please note: the 2012 conspiracy theory is a banned subject here. It is pure crackpot nonsense and we won't feed it.

    Looking at a sky map via Starry Night, I find that Venus is about 6 degrees west of the sun right now. The FOV of that telescope is 16 degrees. Therefore: Venus!

    what are u talking about im talking about astronomy...

    The refrence is to a calander, very usful for predicting usfull astronomy.
    and to show what evidence we can support the obviouse.
    venus would appeare as a tiny dot next to the sun, unlike the photo.

    Take a look here http://lasco-www.nrl.navy.mil/images/C3_desc.html" [Broken]
    This shows how big Venus appears.


    That is Venus in the most current shot just entering the frame!

    The comparison photo of comet neat is how I made the comparison.
    comet neat is almost twice the size of jupiter, in comparison the latest photo above left represents somthing at least that size, if not bigger.

    A binary star?

    latest photos.

    The activity of solar flare you see here confirms a new solar cycle has begun.
