2012 01 02 14:55:00

Image

2012 01 18 23:18:00

BIRS: II/III bursts from a C1 flare

Image

2012 03 09 03:35:00
BIRS: Impulsive phase of M6 flare, huge radio burst, bright flare continuum, reportedly a II just gets into this frequency range that is the first feature visible at 55 MHz at 03:43, later features also have a harmonic ratio that might be a continuation of the II.

Image

2012 03 10 15:56:00
Radio burst, no flare reported

Image

Another M8 flare with a big radio burst: there are lots of short-lived features with apparent harmonic ratios

Image

2012 03 17 20:34:00
