Radio Spectrograph associated to visual mag 2010-0324 8:46UT

A couple of nights ago I was standing outside with binoculars during the early morning hours and saw a sporadic 0.5 to 1.0 mag meteor. I walked inside to see the meteor trace scrolling off my radio meteor observing station.

This was the first time I was able to associate a visual meteor with a radio trace. Hopefully, more will follow with April's Lyrids shows.

The slope of the trace corresponds to the visual observation: the meteor decelerated to the southeast but traveling north. The spectrograph shows an approach slope - the doppler shift decreases with time. The duration of the trace (the vertical dashed lines are at 1 minute intervals) appears longer than the quarter to half second of the visual observation.
