Hi Bill,
Re your ‘melting meteor’ from 2019. We have a match in the NEMETODE dataset – a 2-station capture by Andy McCrea (Bangor, N Ireland) and myself. It suggests a mag 0 sporadic, detected at 90 km altitude and extinguished about 10 km lower, with a 12 km ground track. Its Vg was about 18 km/s, so particularly slow.
Having looked at only a few examples of this nature, they had slow Vg and/or shallow angles of attack to the atmosphere.
Alex.
