[vsnet-j 2319] Fw: [[vsnet-grb 542] GCN/HETE_POSITION]

vsnet-jの皆様

 HETE-2衛星がγ線バーストをとらえたようです。

可能な方は観測してみてはいかがでしょうか。

速報の座標は以下のように出ました。
WXM_CNTR_RA:      6.773d {+00h 27m 05s} (J2000),
WXM_CNTR_DEC:   +19.102d {+19d 06' 08"} (J2000),

位置は今後、改訂される可能性があります。
今後の情報は vsnet-grb-info 等を参考にして下さい。

観測に関するお問い合わせも歓迎いたします。
