Sunspot 1004 of SC24...........but indeed for how long?

BFTP

Having developed so quickly, the odds on are that they'll fade just as rapidly, but at the moment they appear to be holding on. It'll be interesting to see what the active area behind them and on more or less the same latitude produces.

Sort of unrelated because it's more to do with a coronal hole rather than an active region, but northern Scandinavia might be in for a good aurora tonight.

Planetary K index upto 7

Is there a possibility that something could be seen in the North of Scotland?

A-index currently at 27, SFI at 71, K-index now 4 (was 7)...solar wind speed is less than 600km/s and the Bz ain't pointing south, damn.

*pops outside to check the sky* lol

Sunspots..Stereo Behind shows another C24 spot coming into view...first time two 24 spots have followed in succession...the Sun is wakening!

Seems along with this SC24 spot there is also a SC23 spot also forming (middle right). Check the animation here:

There's another C24 spot behind this first cluster.

It certainly looks as if something's happening. Not only is that spot pair sticking around for longer than any recent onces, there's more activity on Soho's magnetogram and in the EIT images than there's been for months:

long time since we,ve seen this sort of thing,

from SIDC today

Indeed, that active area appearing over the eastern limb is the most promising for a couple of years! Fingers crossed.

Well that didn't last long did it?! Sunspot 1005 is already fading and the holograph image shows nothing on the far side either. K-index is back down to 2 (quiet).

What happened to the region on the eastern limb, has that disappeared?

It shows up on the EIT images as an active area, there are vague speckles - but nothing coherent - on the magnetic field images and there are vague hints of faculae (bright areas) on the visible image. I'd guess that there's some sub-surface activity, which might break through the surface to produce visible spots, or might not.

Things do seem to have picked up in terms of solar activity, and not before time too! I had read somewhere (can't remember where) that if it had got to December and the sun was still quiescent then the scientists would have started to get a bit jittery!!

Well now we are content we have the true startings of the cycle we can all look forward to what promises to be one of the busiest cycles any of us has ever witnessed.......which hopefully will give folk as far south a london a chance to see Aurora's :D .

So long as we don't loose satellites from power surges/orbit decays or suffer high latitude power outages from induced currents.......LOL

Here's the link to the NASA webpages for IBEX, the mission due to be launched soon to see what's happening to the heliosphere.

They are already jittery. Cycle 24 already much later than expected and in line with the astrophysicists that forecast this with a true minima set for Cycle 25. If you believe the warmists we are going to reach a peak in 3 and half years by 2012 because the sudden record breaking rebound of the sunspot count....rightio o.

Looking at the magnetogram, there are a few areas of disturbance.

http://sohowww.nascom.nasa.gov/data/realtime-images.html

One is lower half just right of middle (does this look like a SC23 polarity area?), another on the right edge (SC24) and a little further south (the one circled in the post above). Then there are the two on the top area (both SC24) - the spot we've been seeing for the last few days and the area that came around the edge and never really developed into a spot.

Nothing of these areas is really showing on the visible, apart from the spot on the lower right.

There is also a possible spot on the farside. See here: http://www.spaceweather.com/

Yes, the southern hemisphere active area on the magnetogram just right of middle does look like it's SC23 (given that the polarity is reversed in the southern hemisphere), but then, cycles do tend to overlap.

There's a giant solar prominence just emerging over the eastern limb.

Better if it was a giant sunspot :D

Everything comes to those who wait........
