During this period, the moon reaches its last quarter phase on Saturday March 6th. On this date the half-illuminated moon will rise near 2:00 local standard time (LST) and will remain in the sky the remainder of the night. Lunar interference will decrease with each passing night as the moon’s phase wanes and the moon rises later each morning.
During this period, the moon reaches its full phase on Saturday February 27th. This is the worst time of the month to view meteor activity as the bright moon will lie above the horizon all night long. Only the brightest meteors will be visible under such conditions, which will persist all week long.
The AMS received more than 500 reports so far about a morning fireball event that occurred over Alberta, Canada on February 22nd, 2021 around 6:23am MST (13:23 Universal Time).
During this period the moon waxes from half-illuminated to full. This weekend the waxing gibbous moon will set during the early morning hours, leaving the remainder of the night free of interfering moonlight. With each passing night this window of dark sky decreases until late in the period the moon will set at the start of morning twilight.
During this period, the moon reaches its first quarter phase on Friday February 19th. This weekend the slender waxing crescent moon will set during dusk, leaving the remainder of the night free of interfering moonlight.
During this period, the moon reaches its new phase on Thursday February 11th. On that date the moon is located near the sun and is invisible at night. This weekend the waning crescent will rise during the early morning hours but will not cause any interference to viewing meteor activity as long as it is kept out of one’s field of view while observing.
During this period, the moon reaches its last quarter phase on Thursday February 4th. At this time, the half-illuminated moon is located 90 degrees west of the sun, thus it will rise near 01:00 local standard time. This weekend the nearly full moon will rise just after the end of dusk and will lie above the horizon all night long. As lunar interference is present all night long, this is the worst time to try and view meteor activity as the lunar glare will obscure all but the brighter meteors.
