The Sun.... she dances.
A moderate, yet strongest this year so far, solar flare measuring M6.51 erupted on April 11, 2013 at 07:16 UTC. The source of this event is Active Region 1719 located almost in the center of the disk and with Beta-Gammamagnetic field capable of producing strong solar flares.
The event started at 06:55, peaked at 07:16 and ended at 07:29 UTC. A Type II and Type IV radiation emissions were associated with the event indicating a major eruption on the sun with strong coronal ejection and solar radiation.
Additionally, a 10cm radio burst was associated with the event. 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.
Our planet is in the line of fire from AR 1719 and today’s CME is headed our way. A geomagnetic storm category G2 is forecasted for April 13, 2013:
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio – HF (high frequency) radio propagation can fade at higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.

M6.5 Solar Flare + CME / Proton Levels
The strongest solar flare in quite some time took place within the past couple of hours around Sunspot 1719. The moderately strong event measuring M6.5 took place at 07:16 UTC. A Coronal Mass Ejection (CME) is now visible in the latest STEREO Ahead and STEREO Behind COR2 imagery. Because 1719 is now squarely facing Earth, the plasma should be directed this way. This will raise the chances of geomagnetic storming by this weekend. Stay Tuned to SolarHam.com for the latest information.
