The solar eruption of 13 May 2005: EISCAT and MERLIN observations of a coronal radio burst
International audience We report results from EISCAT and MERLIN observations of radio scintillation during a solar eruptive event in May 2005. Anomalous increases in signal strength detected at sites more than 2000 km apart are shown to arise from the detection of a strong coronal radio burst in the...
