Solar and Aurora Activity Chat

Of course the sky to the north is bright twilight now this time of year and is only going to get even brighter for another month. Not helpful...

Scotland could again see Aurora tonight..  If not for the bright moon or lingering twilight.

Just had a look outside to the north and as you say a huge bright moon and the now strong red glow to the north are very visible in a more or less cloud free sky. No aurora can be seen as yet.

QUIET SUN: With no sunspots actively flaring, solar activity is low. NOAA forecasters estimate a slim 1% chance of X-class solar flares today. http://www.spaceweather.com/

M1.0 Solar Flare this afternoon around Sunspot 1760, plus a prominence eruption.

GEOMAGNETIC STORM: A G2-class (Kp=6) geomagnetic storm is in progressfollowing the arrival of an interplanetary shock wave on May 31st. The source of the shock is not known; it might have been a minor CME that left the sun without drawing attention to itself. http://www.spaceweather.com/

CHANCE OF FLARES: Sunspot AR1762 in the sun's southern hemisphere has developed a 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares. http://www.spaceweather.com/

M flare early'er today from sunspot 1792..

Most of Scotland and the Far North of Britain are in for a chance of seeing aurora tonight.

An M6 class flare early'er from sunspot 1762 off the South/West limb..

STORM WARNING: NOAA estimates a 60% chance of polar geomagnetic storms on June 9th when a CME is expected to deliver a glancing blow to Earth's magnetic field. High-latitude sky watchers should be alert for auroras.

THE CME THAT MISSED: NOAA forecasters have downgraded the chance of polar geomagnetic storms today to 25%. A CME expected to deliver a glancing blow to Earth's magnetic field on June 9th did not arrive on time and might have missed our planet altogether. http://www.spaceweather.com/

The sun's activity remains at very low levels today, almost flat lined...

 

 

In fact it's the lowest it's been since July 2012, the only remaining sunspot (1765) continues to decay as it rotates over the West limb

So have we past solar max now? Brutally cold winter this year anyone?!

(NO) CHANCE OF FLARES: Strong solar flares today are unlikely. NOAA forecasters say the odds of an M-flare is 10% and the odds of an X-flare is no more than 1%. The quiet appears set to persist through the weekend. http://www.spaceweather.com/

Yipee!

Have we maxed out?  Is there any sign of reversed polarity yet?

NASA have said it wont be until February until they will know for sure even if we have maxed out already, due to the unpredictability of the double peak.

I noticed that the last few days has seen an upsurge in spots, but only in the south.  Has anyone worked out why this is happening?  It's been a recurring theme this cycle where the north was active then south.  It's only been the last 12-18 months where both hemispheres have been active at the same time.

SOUTHERN SUNSPOTS: So far, Solar Cycle 24 has been lopsided. Sunspots north of the sun's equator have outnumbered sunspots to the south by a significant margin: data. But now the southern hemisphere is catching up. Today a raft of southern sunspots is rotating over the sun's eastern limb:

Solar physicist and sunspot forecaster Dean Pesnell of the Goddard Space Flight Center believes Solar Cycle 24 is likely double-peaked. A surge in southern sunspots could herald the second peak, due in late 2013 or early 2014. This solar cycle has been fairly anemic so far, so it could use a boost; the sun's southern hemisphere could be poised to provide it. http://www.spaceweather.com/
