COMMENTS: The RXTE-PCA observation will start at 98/05/19 16:23:32.00 UT. COMMENTS: RXTE/PCA once tried to follow-up this GRB with COMMENTS: normal BATSE/Locburst follow-up procedure. But as COMMENTS: it turned out that the planned scans of 4 deg x 8 COMMENTS: deg do not cover the BeppoSAX position, we COMMENTS: cancelled the follow-up with updated schedule COMMENTS: and employed the direct slew procedure. We sent COMMENTS: direct slew command at 15:38:52(UT) which is less COMMENTS: than an hour after BeppoSAX alert comes in. COMMENTS: RXTE/PCA arrived at. the BeppoSAX position at COMMENTS: around 15:51 and stayed and stayed there until COMMENTS: 16:18:23. Good time interval was 15:51-15:53 COMMENTS: (only 2 min). We tried to upload scan commands COMMENTS: via update plan but could not make it due to the COMMENTS: limitied time. Since there is an originally COMMENTS: scheduled slew at 16:26, RXTE/PCA follow-up ends COMMENTS: at this time. Detailed analysis is going on. COMMENTS: by T.Takeshima
