During this period the moon reaches its first quarter phase on Tuesday May 2nd. At this time the half illuminated moon is located 90 degrees east of the sun and sets near 0200 local daylight saving time (LDST) as seen from mid-northern latitudes. This weekend the waxing crescent moon will interfere with meteor observations during the evening hours but will have set by the time midnight arrives. This will allow good meteor viewing conditions for the remainder of the night.

During this period the moon reaches its last quarter phase on Wednesday April 19th. At this time the half illuminated moon is located 90 degrees west of the sun and rises near 0200 local daylight time (LDT) as seen from mid-northern latitudes. This weekend the waning gibbous moon will interfere with meteor observations as the bright moonlight will obscure all but the brighter meteors. As the week progresses the conditions improve with each passing night as the moon's phase wanes and it rises approximately 45 minutes later with each passing night.
After three months of low rates, April ushers in two major showers (Lyrids and eta Aquariids) and a temporary upswing in meteor activity. The first of these showers is the Lyrids, which are active from April 18 through the 25th. Activity for this shower is low away from the peak night which expected to occur on Friday evening /Saturday morning April 21/22.

For morning observers the estimated total hourly rates should be near 4 as seen from mid-northern latitudes (45N) and 6 as seen from tropical southern locations (25S). Rates are reduced during this period due to lunar interference.
