Fireball 1 : February 24, 2008 0636:50 UT
Observer's Comments: This fireball passed over the vicinity of Las Cruces, New Mexico.
It was a relatively large ( magnitude -8 ? ) fireball and made only minimal forward scatter radio
reflections as can be heard in movie 2 below. Interestingly, there is a pattern of larger fireballs making
only smallish reflections compared to their size. I am accumulating data on this seeming anomaly.
Movie : Sandia National Laboratories Sentinel system, capture box, no sound.
