Here is the recording of a very beautiful burst, that occurred 17/8/1999 at the end of a day which had begun quietly. The recording was interrupted by the sunset. Did anyone more on the West (the USA or GB) was able to record the continuation?


Here is a burst particularly typical 8/9/1999 with its precursor, his fast ascent and the descent in 'stairs'. It was recorded on 169 MHZ.

burst of 8/9/99

The next day, the other one very beautiful.. It lasted almost one hour, saturated the recorder, we were not there to decrease the gain.

burst of 9/9/99

Here is a continuation of scans of recordings 29/3/2001, 30/3/2001 and 31/3/2001 on 169 mhz. In spite of the average quality (humm!!!) Of these scans ,you can realize the succession of days and of the nights ( so the sun goes to bed also in radio!!!), by looking carefully on the recordings of the flux (at black), at the time of the rise or of sunset you will see fringes of interferometry. On the flux with a single antenna, the flux increases and decreases several times before becoming established. One can understand this phenomenon, by saying that at this moment the antenna is horizontal and there is so interferences between the waves coming directly and those received after reflection on the ground. You can as well see as it is sometimes so strong as recorders 'overflows'.... You will see also the thermic drift of the receivers during the night, difficult to avoid if one does not one uses a thermosated building, as well as ' bip-bip ' every 12 mn about at the beginning and at the night end, it is very probably the heater in a neighbouring house.... On these recordings the speed is of 1mm / mn is the 6cm / hour, the scan in the size a4 every 5 hours. The beginning of the sequence (29/3/2001 during night) is completely in to the right, the progress of the paper is made towards the left.
