With the arrival of May, observers in the tropical areas of the world are enjoying good views of the Eta Aquarids during the morning hours. The Antihelion radiant moves from eastern Libra, through northern Scorpius and into southern Ophiuchus during May. These areas of the sky are south of the celestial equator, favoring observers watching from south of the equator. Northern observers still suffer with low sporadic rates, especially during the evening hours. This situation will not improve until mid-July, when sporadic rates dramatically rise for northern observers. The overall meteor activity is much like April, possibly slightly better in the south and slightly worse in the north. The most favorable time to view meteor activity this month would be during the first week of the month, when the Eta Aquarids are near maximum activity.

During this period the moon reaches its full phase on Saturday May 13. This weekend and for the remainder of this period, the moon will be present in the sky most of the night, limiting the meteor activity to be seen. The
sources of meteors listed below are active during this period but will be difficult to observe. If your sky is transparent and the limiting magnitude exceeds +5.0, then you may be able to achieve some success at observing during this period. The estimated total hourly rates for evening observers this week is near one for those in the Northern Hemisphere and two for those located in the Southern Hemisphere. For morning observers the estimated total hourly rates should be near four for those located in the Northern
Hemisphere and six for those in the Southern Hemisphere. These rates assume that you are watching from rural areas away from all sources of light pollution. The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness and
experience in watching meteor activity. Rates are reduced this week due to intense moonlight.

The full descriptions will continue next week when the moon reaches its last quarter phase and is not such a nuisance to observers.
