Terminal flash
Observation
Yes
Remarks
It moved swifly, maybe 35 degrees in about 5 seconds. First was red and orange in color and about -2 mag. Then started to fragment after 3 seconds and about 15 degrees of movement.
It then terminated after about 30 degrees in a very bright flash of maybe -14 mag. with strong blue and green color. It cast strong shadows during the flash. It started low in the southwestern sky around Libra in our very dark and clear Bortle 2 sky and ended up nearly due west of us near Canes Venatici.
