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.
