Region 1692 erupted with long duration M-class solar flare peaking at 06:50 UTC as M1.2 solar flare on March 15, 2013. The event started at 05:52 and ended at 07:30 UTC. A Full-Halo Coronal Mass Ejection (CME) was observed and it looks to be Earth directed.
A 10cm Radio Burst was associated with the event indicating 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. Region 1692 was still classified with Alpha magnetic configuration at 0:30 UTC today.
The fast moving cloud should directly impact Earth by tomorrow evening.
Space Weather Message Code: SUM10R
Serial Number: 573
Issue Time: 2013 Mar 15 07:53 UTC
SUMMARY: 10cm Radio Burst
Begin Time: 2013 Mar 15 0631 UTC
Maximum Time: 2013 Mar 15 0649 UTC
End Time: 2013 Mar 15 0651 UTC
Duration: 20 minutes
Peak Flux: 150 sfu
Latest Penticton Noon Flux: 123 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.
There are currently 9 numbered regions on the disk, most of them are classified with Beta magnetic configuration. Regions 1692, 1694 and 1695 have Alpha magnetic configuration. Regions 1689, 1690, 1691, 1697 and 1698 are classified with Beta magnetic configuration. Region 1696 has Beta-Gamma magnetic configuration.
NOAA SWPC forecasters estimated 15% chance for M-class and 01% chance for X-class solar flare today.
At 12:20 UTC SWPC issued following alert:
Space Weather Message Code: ALTTP4
Serial Number: 402
Issue Time: 2013 Mar 15 1220 UTC
ALERT: Type IV Radio Emission
Begin Time: 2013 Mar 15 0620 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
