Siding Spring approaches / LONG-duration M2 flare & CME

Geomagnetic Storm Watch
An eventful afternoon. In addition to a noteworthy eruption off the east limb, a minor G1 geomagnetic storm is currently in progress. An enhanced solar wind stream combined with a south pointing Bz is contributing to enhanced geomagnetic activity. Sky watchers at high latitudes should be alert for visible aurora if it is dark outside.

Eruptive Event off East Limb
Good afternoon. An eruption was observed Tuesday afternoon behind the east limb at 18:37 UTC. The event, possibly taking place around old region 2173 from the previous rotation, initially measured M1.1 on the X-Ray scale despite not being directly in view. Solar X-Rays peaked again at M2.2 at 21:05 UTC. We will begin to see source region turn into view over the next few days. Image below by the Solar Dynamics Observatory.

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Oct 14 1840 UTC
Maximum Time: 2014 Oct 14 1847 UTC
End Time: 2014 Oct 14 1858 UTC
Duration: 18 minutes
Peak Flux: 1300 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.
