Big Sunspot Turns Towards Earth

From Space Weather

BIG SUNSPOT: One of the biggest sunspot groups of the current solar cycle has emerged in the sun’s southern hemisphere.  AR1785 has an unstable magnetic field that harbors energy for strong solar flares, and it is turning toward Earth.

These sunspots are a sign that the sun’s southern hemisphere is waking up. For most of the current solar cycle, the northern half of the sun has dominated sunspot counts and flare production. The south has been lagging behind–until now. June brought a surge in southern sunspots, and the trend is continuing in July. This “southern awakening” could herald a double-peaked Solar Maximum due in late 2013-early 2014.

The largest dark cores in sunspot complex AR1785-1787 are as wide as Earth, making the ensemble an easy target for backyard solar telescopes. Amateur astronomers are encouraged to monitor developments, as NOAA forecasters estimate a 40% chance of M-flares during the next 24 hours

  • Maybe that’s what got all those big lizards back when! But if we are to be toast, we’ll never know it—what a relief!

    • Ron Russell, I wish I could remember the details of something I saw/read recently where new dino bones have been found in a place where they were not known to be. Dang. Wish I could remember the details. Yes, I’m going to be, I also prefer not to anticipate it.

    For those interested in such things (which I am) I would recommend Youtube – NASA’s SDO Shows A Little Rain On the Sun. It is an awesome display. On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and a dazzling magnetic display known as coronal rain.

    • Richard, I’ll take a look. Thanks.
