<H5>●2月21/22日</H5> <UL> プロット協定観測の日であったが、夕方から低い雲が垂れ込み最悪の天気。ところが３時過ぎに目を覚ますと、そこそこの上天気。対象となるはずのしし座付近は大きく西に傾いたため、うしかい座周辺をパトロールする。かんむり座西部で群活動が見られた（２月かんむり群としてはやや時期が遅いか）他は特に異常なし。 </UL> <H5>●2月23/24日</H5> <UL> 観測中強風が吹き荒れ、修行のような１時間だった。しし座周辺の活動は平穏そのもので特に異常なし。 </UL> <DIV align="right" class="author">〔東の観測装置〕</DIV> <HR size="1"> <DIV align="right" class="jump">| <A href="../../index.html"
