Hi ! newbie mistakes in my first observation. I hope It will never occur
again!... I used the local time date (25APR) in my report, and I was
reporting UTC TIME (26APR)
 :-( Im sorry. I mispelled also my position... :-(


It was watched from 20.7567N -107.3736W , from 022630UTC to 022800UTC


CORRECT:   20.75439N -103.37516W alt 1562meters , from 022630UTC to
022800UTC 20200426.

Im very sorry.
