1 Introduction

BAT triggered on GRB 080607 at 06:07:27 UT (Trigger 313417) (Mangano et al., GCN 7847). This was a 1.024 sec rate-trigger on a long burst with T90 = 80 sec. Swift slewed to this burst immediately and XRT began follow-up observations at T + 82.1 sec, and UVOT at T + 100 sec. Our best position is the UVOT location RA(J2000) = 194.94665deg (12h59m47.20s), Dec(J2000) = +15.91965deg (+15d55 10.74 ) with an error of 0.5 arcsec (90% confidence, including boresight un- certainties).

GRB 080607 has also been seen by Konus Wind (Golenetskii et al., GCN 7862), by the Mini- Calorimeter (MCAL) on board AGILE (Marisaldi et al., GCN 7866) and by INTEGRAL/SPI- ACS, confirming the bright, multi peak structure of the prompt emission reported in Mangano et al., GCN 7847 (Beckmann, private communication).

The optical afterglow was detected by a number of ground based telescopes, e.g.: ROTSE III (Ru- jopakarn et al., GCN 7846), Super-LOTIS (Updike et al., GCN 7848), KAIT (Chornock et al., GCN 7856), RTT150 (Zhuchkov et al., GCN 7861), CrAO (Rumyantsev et al., GCN 7891).

An infrared afterglow detection has been provided by PAIRITEL (Miller et al., GCN 7850).

A redshift estimate z = 3.036 was provided by the Keck/LRIS based on the detection of a very strong, damped Lya profile and metal-line transitions of OI, SiII, CII, SiII* among others (Prochaska et al., GCN 7849).

1 Introduction

BAT triggered on the long GRB 080319C at 12:25:56 UT (Trigger 306778) (Pagani, et al., GCN 7442), a burst with T90 = 34 ± 9 sec. Swift slewed immediately to the burst. The XRT and UVOT detected the afterglows in observations starting 224 sec after the trigger. The optical afterglow was detected in early observation by the KAIT telescope (Li,et al., GCN 74431), with Super-LOTIS (Williams, et al., GCN 7443) and by RAPTOR (Wren, et al., GCN 7477) in the R band. No radio source was detected by the WRST (van der Horst, et al., GCN 7481). The burst was also deteced by the INTEGRAL SPI Anti-Coincidence System (Beckmann, et al., GCN 7450), by the AGILE Mini-Calorimeter (Marisaldi, et al., GCN 7457), by Konus-Wind (Golenetskii, et al., GCN 7487) and by the Suzaku Wide-band All-sky Monitor (Onda, et al., GCN 7508). The spectroscopic redshift of this burst is z = 1.95, measured using the GMOS-N instrument on Gemini-North (Wiersema et al., GCN 7517).
