The Quadrantids meteor shower peaks tonight at 02h UT. Oops. full moon? Watch the radio instead!

This annual shower usually puts on a great show, but only for a brief period. The almost full moon will hamper visual observation, but radio observers should have a great advantage in being able to observe under almost any conditions.

In northern Europe (within approx 800km of Dijon, France) tune your scanner to exactly 143.049 MHz using upper-side-band mode. Closer to the transmitter a dipole or discone antenna will work, but further afield a good yagi pointed towards Dijon will be needed). If you hear steady or slowly descending tones you may be hearing the transmitter directly or via aircraft scatter. Now listen for the “pings” of meteors refracting the signal from the head and/or train of the meteor. They’ll come more often as the peak time of 02h UT is reached, maybe 10 to 50 per minute depending on how good your reception is.  

In 2008 I recorded the activity in the above image from the Quadrantids shower using the video carriers of two analogue VHF TV frequencies in Spain and eastern Europe over a time period of 21 hours. Each vertical line is a meteor.

If you have no radio, you can watch the action from the Norman Lockyer Observatory's S.P.A.M. network of observers across the UK.
