Sunspot 1890 Is Now Directly Earth Facing

   Monster sunspot 1890 has today rotated into a direct line with Earth, raising the possibility of any geoeffective events over the next 48-72 hours. The size of 1890 has decreased some over the past few days, with a area size of 920 being reported by solen on Nov 8th.

   Even with the decrease in size sunspot 1890 retained a magnetic delta structure in the southeastern section making chances high that we will see more activity from the sunspot over the next few days. NOAA forecasters are estimating a 60% chance of M-class solar flares and a 20% chance of X-flares for Nov 8th.

CHANCE OF FLARES: Big sunspot AR1890 has quieted since the X-flare of Nov. 8th, but this could be the calm before the storm. The sprawling Jupiter-sized sunspot has a 'beta-gamma-delta' magnetic field that harbors energy for strong flares. NOAA forecasters estimate a 50% chance of M-class flares and a 20% chance of X-flares on Nov. 10th. credit: Spaceweather.com

M3.3 Solar Flare From Sunspot 1718 - April 12, 2013

   Today we had a M3.3 solar flare from sunspot region 1718 peaking at 20:38 UTC
Today's M3.3 flare comes on the heels of the M6.5 solar flare that occurred yesterday (April 11th) around sunspot region 1719 peaking at 07:16 UTC.

 

   At this time the M3 flare from today does not appear to have produced a CME. We will however be monitoring the solar images to see if we see any signs of this changing. The M6 flare from yesterday did however produce a Earth directed CME that is due to arrive sometime in the early hours of Saturday April 13, 2013 when a moderate G2 geomagnetic storm is forecasted to occurred.

CME Impact! March 17, 2013

 
   The full halo CME from Friday March 15th has arrived  at Earth early Sunday morning at around 05:30 UTC . The Solar wind and interplanetary magnetic field show a shock signature from this CME now arriving.
At the time the CME came in contact with Earths magnetosphere a geomagnetic disturbance commenced with the Bz fluctuating between minus 20 and plus 15 nanoTeslas.
The Solar wind speed jumped to around 700 km/s and the interplanetary magnetic field Bz component is turbulent around -15 nT.
This brought on a moderate Geomagnetic storm.

   At this time geomagnetic storm level has reached storm levels of G2 (K=6). These conditions are expected to persist well into the early morning hours of tomorrow, Monday March 18.

Aurora may be seen as low as Montana, Michigan, New York, Wisconsin to Washington state, as well as other high latitude regions. To know where Auroras can be seen, look for the Aurora ovation model located in the left hand column of this site.

CME Arrival Due Today - Updated Hourly

 

   Today we are awaiting the arrival of a Earth directed CME that was ejected from the solar surface on March 15, 2013. While we wait for this CME to arrive, we thought it would be a good time to update everyone with the info we have on this CME. We have our original report on this CME that you can view HERE.  A geomagnetic storm watch is in effect for the next 24-48 hours when this CME is expected to arrive with G1 (Minor) geomagnetic storm expected for the Saturday March 16th and G2 (Moderate) storming expected for Sunday March 17th. (click HERE to view the Geomagnetic Storm Scales)

CME arrival is due Today:
March 16th @ 17:00 UTC - March 17th @ 03:00 UTC
