>Very few observations of the 1997 Quadrantids have arrived until now.
>Particularly, the weather in North America was preventing many observers
>from watching the maximum of this shower, which was expected for about
>11h UT on January 03. The only observer who covered that period was Norman
>McLeod. He reported increasing ZHRs exceeding 100 until the end of his
>observing session. Mark Davis was the second lucky observer in the US
>with a ZHR well over 100 too.
>
>European observers saw the ZHRs increasing from 20 in the evening of
>January 2, 22h UT, to ZHR=60 on January 3, 4h UT. The following (European)
>night saw a ZHR=50 in the evening and ZHR=20 around 1h UT on January 4.
>These very raw data are based on the observations of

>Rainer Arlt (Germany), Felix Bettonvil (the Netherlands), Detlef Koschny
>(Germany), Ralf Koschack (Germany), Ake Lysell (Sweden), Jurgen Rendtel
>(Germany), Marko Toivonen (Finland), Manuela Trenn (Germany), Ilkka Yrjola
>(Finland).

>I hope more observations will permit giving a ZHR graph soon.
