2006

The following colorgramme shows the radio meteor counts for the month of November 2006. The horizontal axis shows the day of the month and the vertical axis the local time (UT).

Detection is operating on 55.25MHz, 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 November 2005. The horizontal axis shows the day of the month and the vertical axis the local time (UT).

The elevated counts on the morning of 4th November are associated with a small number of larger fireball events. You can see the spectrum plots from this event here. This possibly records a Taurid fireball. 

Felix Verbelen and Patrick Vanouplines recorded a high number of long reflections during the morning hours (UT) of November 20. I too recorded a number of long reflections during this period. These are echoes from Leonid meteors.

The meteor v8.2 settings were changed on the 14th November - the delay was increased to 4.01 seconds. From this date the settings are:

Threshold high 25

Threshold low 100

Delay 4.01 sec

CSA OFF

RAW OFF

This has resulted in lower counts from that time onwards.

2004

Solar activity increased sharply on Oct. 30th 2004. The source was fast-growing sunspot 691, which has unleashed several strong flares, including a brief X-flare. These explosions hurled coronal mass ejections (CMEs) toward Earth. This matter swept passed the Earth around midday on the 1st November. This produced unusual ionospheric propagation conditions and false meteor counts. These counts have been removed from my results.

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


The same information is presented as a daily rate in the chart below.

2003

The following colorgramme shows the radio meteor counts for the month of November 2003. The horizontal axis shows the day of the month and the vertical axis the local time (UT).

The annual Leonid shower runs from 15th to 20th November, but is  predicted to produce several peaks of activity during this period.  One peak, possibly seen from the UK, is predicted to occur during the early hours 19th of November. Data for the afternoon of the 19th and 20th November was lost due to solar activity.

2002

The following colorgramme shows the radio meteor counts for the month of November 2002. The horizontal axis shows the day of the month and the vertical axis the local time (UT).

 

The Leonids shower dominates the meteor count for this month. The meteor counts are seen to reach a sharp peak some time between 04:00 and 05:00 on the morning of the 19th of November. There is secondary smaller peak between 06:00 and 08:00 of the same day. This period is examined in greater detail here. I've included my observations of the 2002 Leonid storm here.
