2003

Meteors Watch Opportunity 2003 for Singapore - yk Chia No instruments are needed - just bring yourself under the sky. So far the most reliable showers proven successfully in S'pore were Perseids, Leonids and Geminids. From time to time I will include other new and interesting candidates as they surfaces. ( Oct 19 '03 - Orionids successfully detected on Oct 18, 19 predawn sky with sensitive ccd/video system) - a consolation to nearly all missed meteors this year? - Nov 14 A handful of Leonids from the rather old dust trails ( 1499) were detected by video recording system - .. next onto 1733 debris..
