AbstractARTEMIS IV is a Franco-Hellenic radiospectrograph ARTEMIS-IV operated by the University of Athens at Thermopylae, Greece. ARTEMIS IV solar radio spectrograph covers the frequency range of 20 to 650 MHz, using two receivers operating in parallel. The Global Spectral Analyser (ASG), a sweep frequency receiver and the Acousto-Optic Spectrograph (SAO), a multichannel acousto-optical receiver. The sweep frequency analyser (ASG) covers the full frequency band with a time resolution of 10 spectra/s. The high sensitivity multi-channel acousto-optical analyser covers the 265-450 MHz range, with high frequency and time resolution (100 spectra/s); its recordings are used, mostly, for the study of fine structures We present some interesting solar events with fine structure observed during the period of October 2003 to November 2003.The presentation (PDF) |
