Next up: May 4-6, 2013 before dawn, the Eta Aquarids
This meteor shower has a relatively broad maximum – meaning you watch watch it for several days around the predicted peak. The radiant is near the star Eta in the constellation Aquarius the Water Bearer. The radiant comes over the eastern horizon at about 4 a.m. local time; that is the time at all locations across the globe. For that reason, the hour or two before dawn tends to offer the most Eta Aquarid meteors, no matter where you are on Earth. At northerly latitudes – like those in the northern U.S. and Canada, or northern Europe, for example – the meteor numbers are typically lower for this shower. In the southern half of the U.S., 10 to 20 meteors per hour might be visible in a dark sky. Farther south – for example, at latitudes in the Southern Hemisphere – the meteor numbers may increase dramatically, with perhaps two to three times more Eta Aquarid meteors streaking the southern skies. For the most part, the Eta Aquarids is a predawn shower. In 2013, the waning crescent moon should not intrude too greatly on the Eta Aquarid shower. The most meteors will probably rain down on May 5, in the dark hours before dawn. But watch on May 4 and 6 as well! The broad peak to this shower means that some meteors may fly in the dark hour before dawn for a few days before and after the predicted optimal date.
