2007

The following colorgramme shows the radio meteor counts for the month of July 2007. The horizontal axis shows the date and the vertical axis the time (UT).

The system was taken out of service, to perform other duties, between the 23rd and 25th. A power failure on the afternoon of the 26th resulted in the loss of data until mid-morning on the 27th. The other lost data was due to sporadic E. The modest increase in counts, during the afternoon of the 19th July 2007, looks genuine and to have a meteoric cause.

Detection is operating on 55.25 MHz, using a three element Yagi, bearing 180 deg ETN and 10 degree elevation.

2005

The following colorgramme shows the radio meteor counts for the month of July 2005. The horizontal axis shows the date and the vertical axis the time (UT).

Sporadic E has been a problem throughout the first half of July. Counts affected by sporadic E have been removed leaving the dark spaces. The July results may have recorded a fireball seen over Wales, southern England, Guernsey and Belgium at 20:19 on the 16th July 2005.

Detection is operating on 55.25MHz, using a three element Yagi, bearing 180 deg ETN and 10 degree elevation.

2004

The following colorgramme shows the radio meteor counts for the month of July 2004. The horizontal axis shows the date and the vertical axis the time (UT).

Detection is operating on 55.25MHz, using a three element Yagi, bearing 180 deg ETN and 10 degree elevation.

A RF band pass filter was inserted into the aerial feeder at 15:20 UT on the 27th July 2004.

The high counts during the evenings of the 1st and 2nd July are probably caused by unusual propagation conditions and are not related to meteor activity.
