Another not so little dance from Sol

Sol's 1748 blasted of another X Class flare yesterday- with a corresponding filament breaking away on the almost opposite side of the sun.... For action there is an equal and opposite reaction ;)
The CME from this X1.2 Flare might give earth a slight glancing blow, but any flares from today forward will definitely be in line of sight of Gaia.

NOAA has again upgraded the flare watch to 80% for an MClass and 50% for an XClass flare in the next 24-48 hours.

1748 Flares Again (X1.2)
Sunspot 1748 does it again. For the fourth time, the active region has produced a major X-Class solar flare. The latest event measured X1.2 and peaked at 01:47 UTC. The eruption was associated with Type II and IV Sweep Frequency Events and a 10cm Radio Burst (Ten Flare) measuring 490 sfu. I will provide further updates regarding a possible Coronal Mass Ejection. Stay Tuned to for the latest updates.

CME Update: The latest X-Flare event did generate a Coronal Mass Ejection. Because the blast location is still not in prime position, a majority of the plasma was directed away from Earth. There does appear to be a very minor Earth directed component, however it should have only a minor effect on our geomagnetic field at best. Images below by LASCO C2.
X1.2 Solar Flare (Early Tuesday) - SDO
SUMMARY: 10cm Radio Burst
Begin Time: 2013 May 15 0133 UTC
Maximum Time: 2013 May 15 0143 UTC
End Time: 2013 May 15 0150 UTC
Duration: 17 minutes
Peak Flux: 490 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.
