REMARKS: Seeing throughout session was medium-good.
Meteor #13 was noted as a possible UPG (Ups Pegasid, non-IMO shower).
Meteor #24 was seen to flare from mag 2 to mag -3 through 20 degs.
Session was hampered by increasing cirrus overcast, which obscured
successively larger areas of the sky until observing was impossible.
(Actually at the point of worst overcast, the LM may still have been
around 5.0, but still too disappointing for a fatiqued observer...)
NOTE:
Column "ELEV/CONSTEL" contains which constellation a meteor was
observed in, if noted, or else the elevation (angular altitude)
at which the meteor was seen. This was only noted for meteors
which either ended or began at less than 45 degrees elevation.
