Solar Studies
Sunspot cycle 23 ended during fall 2008 and the Sun was relatively quiet until May 2009. At that time we started monitoring solar activity. We presently operate two detection systems for solar emissions, one in the HF frequency band and another in the VHF/UHF frequency bands, as described below. The solar emissions generally are related to flare activity, the causes of which are not yet fully understood.
1) High-frequency system operating in the approximate range of 3~30 MHz (primarily 15~32 MHz) called the HF System. Click here for information and data for our HF System. A block diagram is shown below.
2) Solar spectrometer operating in the range of 45~870 MHz called the e-CALLISTO system. Click here to view information and data for our e-CALLISTO System. We participate in the e-CALLISTO solar spectrometer network sponsored by the Swiss Institute of Technology, ETH Zurich. A block diagram is shown below.
