Fireball 1
: May 31, 2008 1028 UT (4:28
am MDT)
Observer's Comments: Clear night. The first fireball listed
here was quite a big one, occurring over southern New Mexico.
It created one of the longest forward scatter radio reflections I have
ever received.

of the time of the meteor. 61.250 MHz reception above
white line, 83.250 MHz below white line.
Fireball occurs at the 10:28 ut marker and continues into the second chart
until 10:35 UT. The fireball that can be seen on the
spectrogram at 1027 UT was a different meteor, unrelated to the 1028 UT
event. A movie of the 1027 UT meteor is down the page.

This particular meteor was not captured
by the Sentinel system but my secondary video system caught it with sound.
This is another very long radio reflection. In the movie below the meteor
is very hard to see up in the upper left portion of the screen.
