From: Huan Meng, Beijing, China Date: Wed, 20 Nov 2002 17:26:56 +0800 Unexpected Peak at around UT 2200, Nov. 18!!! (Nov. 18/19 UT) We observed in China for 3 days, i.e. 17/18, 18/19, 19/20. On the night of 17/18, I lay down on snow with the limiting magnitude over 6! I made observation of 1h in moonlight and Dr. Jin Zhu made another one after the moon-set. These observations haven't been processed yet, and reports will be sent soon. I think the most important event happened on the night of 18/19 (UT 2200, Novemver 18, 2002). We met an unexpected peak! The population index was rather low, our preliminary results suggested it might be about 1.7, coorespending to the ZHR_max of approximately 200! Unfortunately, on account of the bad weather and boring moonlight, we had only an LM worse than 4. However, 5 individual observers' contribution may make up the disadvantage. I think this event may caused by some very old dust trail. So, predictions may not consider dusts with so many revolutions(?). We also noticed the result of Japan and Iran (by Hiroshi Ogawa and the gourp of Iran)! Both fluxes were lower than ours. And at the end of Iranian observations, it increased for the European peak. So, our result might be just the very top of the unexpected peak. Yesterday, the weather turned worse, so did the flux. Reports will be sent soon, too. === Visual Observing Form - Summary Report Day: 18/19 Month: 11 Year: 2002 Begin: 20h31m End: 22h08m Location long. 115?42' 51.7"E latit. 40?19' 01.3"N IMO code: Site: Huailai, Hebei Province Country: China Observer: Huan MENG IMO code: MENHU Surname (family name) with CAPITAL LETTERS;
