REMARKS: During break AT 8h10m UT while looking down, there was a VERY
VERY bright flash of a green fireball that lit up the terrain. Must have
been as bright as the full moon, it left shadows. Looking up the meteor was
a Perseid with a greenish train that lasted nearly 60 seconds directly
overhead. The train was 40 degrees long.
