ALERT: Type II Radio Emission
Begin Time: 2013 May 13 0210 UTC
Estimated Velocity: 2347 km/s
SUMMARY: 10cm Radio Burst
Begin Time: 2013 May 13 0208 UTC
Maximum Time: 2013 May 13 0219 UTC
End Time: 2013 May 13 0222 UTC
Duration: 14 minutes
Peak Flux: 320 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.

Nelle ore precedenti nella stessa regione si sono registrate altre due esplosioni che hanno provocato solar flares di classe M. Questo evento è il primo del 2013 ed il Sole, entrando nel picco della sua attività, potrebbe riservare diverse sorprese. Cosa dobbiamo aspettarci nelle prossime 24 ore? Vista l’intensa attività di questa complessa regione solare sono possibili altri solar flares. Le possibilità per un nuovo brillamento di Classe X sono al 30%, mentre aumentano al 70% per altri di classe M. Restate collegati per ulteriori aggiornamenti.
Space Weather Update: A major X-Class solar flare is currently in progress.
A new region just over the limb has produced 2 small M flares starting yesterday toward the end of the day. An X flare is in progress. It is currently at X1.7 and that appears to be the maximum. What can we expect in the upcoming 24h?
Due to the constant flare activity from this new region, new flares are possible, even X-class flares. But it will take a few days before we actually see the region fully visible and to determine it’s magnetic complexity. M-class flare probability: 70% chance – X-class flare probability: 30% chance. Stay tuned here for further details.
