SPA Meteor Section Results: January-March 2003

Analyses and discussions from results collected by the SPA Meteor Section from January to March 2003 are presented. Comments on the continuing, indeed worsening, problems of radio meteor observing are given, together with brief remarks on further minor revisions to these report articles. The Section's final 2003 Quadrantid results are included. The radio results are unchanged from those previously published, with three probable maxima at: 12h+-1 UT on January 3 (solar longitude (eq. 2000.0) = 282.65 +- 0.042; weak and not well confirmed); 23h15m +- 4h UT on January 3 (solar longitude = 283.128 +- 0.17 deg; the strongest peak, but not clearly defined); and 10h +- 2h UT on January 4 (solar longitude = 283.585 +- 0.085; well confirmed, although weaker than the approximately 23h UT one). Visually, two maxima were found, the marginally stronger at 01h30m UT on January 4 (solar longitude = 283.56, mean ZHR = 90+-16), the other at approximately 10h +- 0.5h UT on January 4 (solar longitude = 283.58 +- 0.021, mean ZHR at 10h30m UT is 77+-14). Other significant highlights from the quarter were some interesting single-observer results on the gamma-Normids in March, and a number of fireball, meteorite, and unusual meteoric non-event, reports, including a possible medium wave radio detection of a simultaneous fireball sound on February 1/2, a nonexistent `meteor storm' report from February 9/10, some fascinating details on the infrasound detection of a fireball seen from the Netherlands and southern England on February 19/20 at 18h13m UT, and the Park Forest meteorite fall over the city of Chicago, USA, on March 26/27.
