REMARKS:
I decided to watch for an hour at each end of the night, to conserve
energy for future sessions and to look for any obvious increase in
activity (there wasn't). Some clouds were present from dissipating
thunderstorms.
Meteor 4 fell down from the radiant to the NE horizon.
Meteor 25 was noted as a possible North Delta Aquarid.
Meteors 23 and 28 were probably associated with the Northern Apex source.
