gibbous

“The waning gibbous moon will severely compromise this shower at the time of maximum activity,” notes the American Meteor Society.

Viewing will also be hampered by the waning gibbous moon at 93% of its full illumination and present in the sky throughout the night.

The Moon will be in a waxing gibbous phase – going from half moon to full moon.

Even now, however, a waning gibbous moon will still somewhat impede viewing conditions.

The waxing gibbous moon will set around midnight, ushering in excellent viewing conditions later in the night and predawn hours.
