The Detection of Sporadic E, Aurora and Meteors by using 
Radio Spectrum Analysis - CME and SOLAR FLARE Gallery
by Andy Smith G7IZU

Sept 2005
 
This was an unusual month for the sun, during the year prior to the supposed
solar minimum. A sunspot - area 798/808, unleased a series of huge X-class
explosions during a very active week. In fact it was the most active period for many years. 
 
During experiments monitoring the HF band, I recorded a few "HF fadeouts" which
coincided with solar flares coming from this sunspot. The frequency being monitored
was the BBC World Service on 17.640 MHz.

A suspected CME (coronal mass ejection) strikes the upper atmosphere,
causing ionization similar to an aurora (the fuzzy traces). There is also
a sporadic E opening in progress (the solid lines).
