| Zusammenfassung |
| 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
distant off-axis response of the MERLIN and EISCAT antennas. These
observations show that EISCAT is capable of detecting the signatures of
explosive events in the solar atmosphere with a high degree of time
resolution. We further suggest that the highly time-structured variation in
signal strength caused by distant off-axis detection of a powerful coronal
radio signal could provide an explanation for previously unexplained
anomalies in EISCAT IPS observations, as well as being a potential source of
errors in active observations using radar codes with a completion time
longer than the time-variation of the coronal signal. |
