A long duration solar flare eruption measuring M1.2 took place at 13:10 UTC Wednesday, June 13, 2012. The flare was centered around Sunspot 1504. Associated was Type IV Radio Emission and a 10cm Radio Burst (TenFlare).  The event lasted nearly 2 hours. Sunspot 1504 is now in a great position for Earth Directed explosions.

NOAA forcasters estimate a 40% chance of M-class solar flares today as a phalanx of sunspots turns toward Earth. The most likely source of geoeffective eruptions is Sunspot 1504, which has grown into an active region almost 10 times wider than Earth.

ALERT: Type IV Radio Emission
Begin Time: 2012 June 13 13:25 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2012 June 13 13:32 UTC
Maximum Time: 2012 June 13 13:43 UTC
End Time: 2012 June 13 13:47 UTC
Duration: 15 minutes

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.
