    For Ed Cannon on Jan.21, I expect the flashes to start around 01:24 UTC near
    RA 02:58 Dec.-7.5
    
    If my derived data are correct, this episode would stop being specular N of
    31.5N, and gradually become fainter near RA 02:30, Dec.-8.
    
    There could be an early episode around 22:00 at RA 23:30, Dec.-9.5.
    At lat.40N, long 98W it could be as early as 21:00 UTC, RA 22:30, Dec. -10.5

    I would prefer the time of brightest flash, otherwise start and end of 1x
    visibility, otherwise end of 1x visibility. The end of entire pass is too
    uncertain, given its length and lacking (consistent) magnitude limit.
