Beautiful Solar type II and III radio emission
The space based STEREO A and B observatories also recorded type II radiation (slow negative frequency drift) near 2 MHz, following a type III burst (fast negative frequency drift).
My thanks to the Culgoora and STEREO Observatory Teams. The spectra they publish is a wonderful complement to the charts recorded (at much higher time resolution) with Radio JOVE Educational Program Kits. I greatly enjoy studying all the data, it helps me to better understand the great complexity of Solar radio events.
I hope to study more detailed STEREO spectra in a few days, once the higher resolution data is downloaded from the spacecraft.
The image includes a chart with the positions of the Earth, the STEREO Observatories, and planets Mercury and Venus.
Mercury, Venus, and Jupiter are currently in a lovely conjunction, as seen from the Earth at dawn.
