Reports Report 900a (Event 900-2017)

Observer
Name David S
Experience Level 5/5
Remarks Date 21.2.17 Time 0024 GMT Lat 53.725, Long -1.860 Two observers (C.Ingham and self) facing South. GREEN fireball - the greenest I have ever seen. No other colours detected. Approx app Mag -5 No sounds, no fragmentation. Track First sighted ~2 deg south of Denebola (beta leonis). Movement, slightly East of directly south, almost perpendicular to horizon. Track appeared to wink out in the Corvus/Crater region. Track length: approx 25 deg Speed: quite fast for a fireball but quite slow for a meteor. Duration of observation: ~3 sec. Variablitity: Object faded and rebrightened 2 sec into its track. This may or may not (50% estimated chance) have been due to a thicker band of cloud (see below) rather than intrinsic. Ionization trail: none clear - may have been lost in haze. Note: Sky was covered in mostly uniform thin cirrus haze which gave the fireball a small green halo (disc not ring).
