Solar Flare Report — possible Radio/GPS interference March 12th and 13th 2015

 Solar Flare Report — possible Radio/GPS interference March 12th and 13th 2015

  • Why not have some excitement on Friday the 13th?  At least it won’t be cloudy with a chance of meatballs.
  • Visit it Space Weather website for more details about Solar Flares and how they can affect radio signals and satellites.

*Be cautious of collecting GPS Data during high flux Solar Flare conditions.

**Not only can Solar Flares affect your GPS receiver but also the GPS Base Station receiver that you are trying to correct against via Real-time and or Post Processed.

CHANCE OF STORMS: Friday the 13th could be a lucky day for sky watchers. Several minor CMEs propelled toward Earth earlier this week by active sunspot AR2297 are expected to arrive en masse on March 12th and 13th. Their collective impact could spark bright auroras around the Arctic Circle. NOAA forecasters estimate a 60% chance of G1-class geomagnetic storms when the CMEs arrive. Aurora alerts: text, voice

X2-FLARE AND RADIO BLACKOUT: All week long, sunspot AR2297 has been crackling with solar flares. Yesterday it produced a really big one. On March 11th at 16:22 UT (09:22 PDT), Earth orbiting-satellites detected an X2-class flare. The blast zone was larger than Earth itself:

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.
