From: Brian CudnikPossible eta Aquarid impact recorded in California at 4:52 U.T. May 7 U.T. - May 8To: dunham@erols.com Subject: Lunar eta Aquarids David, can we coordinate some IOTA observers to systematically monitor the Moon from May 6 to 10 for impacts by lunar Aquarids? The shower actually peaks around May 4/5, which closely coincides with New Moon, but two days later, people can begin monitoring the moon for meteor hits. According to Sky & Tel, the meteor shower should remain close to its peak intensity from May 6 to 10, which is when I am coordinating a watch. I've provided a lunar blank and report form on the ALPO/Lunar Meteoritic Impact Search website that people can use to plot and report impact sightings. These meteors are swift (Earth-relative velocity 66 km/sec, almost as fast as the 71 km/sec of the Leonids), meaning more energy is available for creating visible flashes. The sub-meteor point is roughly 60 deg. west of the CM meridian, near the lunar equator, so the best place to watch is from the terminator to just east of the selenocenter. For more, see the ALPO lunar impacts Web page. Brian Cudnik Current Acting ALPO/LMIS coordinator
