Observer's comments: This was the peak period of the annual Quadrantid meteor shower. Here are some specimen Quadrantids
as captured with a Sandia National Laboratories Sentinel video camera system merged with my forward scatter radio array.
Specimen Quadrantid 1: January 03, 2009 1301 UT
Sonic Movie 1 : Ashcraft's dual forward scatter system; video and stereo sound:
Near peak Quadrantid. Good reflection and doppler. Forward scatter reception is dense with multiple meteors reflecting in.

Radio spectrogram of the time of the above meteor. 61.250 MHz reception above white line, 83.250 MHz below white line.
Meteor reflection begins during the 1301 UT minute. Multiple meteors reflecting simultaneously.
Specimen Quadrantid 2 : January 03, 2009 0913 UT
Sonic Movie 1 : Ashcraft's dual forward scatter system; video and stereo sound:
Generally, there was no separation between meteor reflections for most of the peak night.

Radio spectrogram of the time of the above meteor. 61.250 MHz reception above white line, 83.250 MHz below white line.
Meteor occurs during the 0913 UT minute. Multiple meteors occuring.
Specimen Quadrantid 3 : January 03, 2009 1255 UT
Sonic Movie 1 : Ashcraft's dual forward scatter system; video and stereo sound:
This meteor appeared near the predicted peak minute of this year's shower.

Radio spectrogram of the time of the above meteor. 61.250 MHz reception above white line, 83.250 MHz below white line.
Meteor reflection begins during the 1255 UT minute and is a part of multiple meteors received simultaneously.
Specimen Quadrantid 4 : January 03, 2009 1316 UT

Specimen Quadrantid 5 : January 03, 2009 1130 UT
Sonic Movie 1 : Ashcraft's dual forward scatter system; video and stereo sound:
This was a typical looking Quadrantid and possibly a typical Quadrantid radio reflection, too
