During this period the moon reaches its last quarter phase on Saturday February 15th. At this time the moon will lie 90 degrees west of the sun and will rise near 01:00 local standard time (LST). These conditions are fine for the slow evening hours when the moon lies below the horizon. The more active morning hours will have interference from the moon but one can still obtain useful data as long you face away from the lunar glare. As the week progresses the waning crescent moon will rise later in the morning, allowing less interference during these more active hours.
