Huge Sunspot 1339 - One to watch!

    Definately thought this warranted a new thread from the lingering other one.

    A huge new sunspot has made it's appearence on the suns NorthEastern limb, one of the biggest in years.

    It had already unleashed an M4 class flare, but just in the very recent times, it has unleashed a big X2 class solar flare. The sunspot isn't very geofective at the current time(not in a great position for CME's to hit us), so this X flare mightn't have a significant effect on the Earth (if any), but in the coming days as it rotates into a better position, the potential for further large eruptions is very good.

    Weather forecast isn't too bad for the next 3 days, so hopefully something good happens for us, as we've been really unlucky with cloud cover the last few times!

    Does that mean we might get to see cool sh!t in the sky?

    Was Halloween not good enough for you? :)

    Yep fingers crossed it means some aurora on the way.

    what does this mean for upcoming winter? and what are sunspot count currently at? what were they at during summer and this time last year?

    That's seriously for another forum.

    See "The Sun Is Dead, Mini Ice age" in this forum for a detailed study.

    The Sun should be at the heights of its routine active cycle, but it's so low that some are saying there is no high period ~ periods last on average 11 years; an unknown length of time for extended quite periods ~ 70 years has been observed.

    No Sunspots = bad weather or worse weather. Plenty of Sunspots = good weather or better weather.

    The CME from the X2 class flare is not heading our way, but in the coming days sunspot 1339 will be slowly rotating into more geofective positions on the sun, so further eruptions in the coming days would start to effect earth.

    Weather- Looks like very good weather out till Tuesday, before expected rain next Wednesday.

    November 4, 2011X-FLARE: Earth-orbiting satellites have just detected an X2-class solar flare. The source is huge sunspot AR1339. If a CME occurred, chances are it is not earth-directed given the far eastern eruption site on the solar disk NOAA said. This turbulent region of the Sun will be facing Earth directly in about 5 days. A solar flare is a sudden brightening observed over the Sun surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy (about a sixth of the total energy output of the Sun each second). The flare ejects clouds of electrons, ions, and atoms through the corona into space. These clouds typically reach Earth a day or two after the event. The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.

    Can mega spots set off other spots? or are they all created independently?
