GRB 090515: Super-LOTIS Upper Limits
Williams, Updike, & Milne
Posted by Grant Williams
09/05/15 08:00:24 GMT

The robotic 0.6-m Super-LOTIS telescope began observing the error box of GRB 090515 (Swift Trigger 352108, Beardmore et al. GCN 9356) at 04:45:52 UT, 43 seconds after the trigger. Our initial observations include 5 x 10s exposures, 5 x 20s exposures, and 30 x 60s exposures, all in the R-band. We do not detect any variable sources or afterglow candidates within the XRT error box in our earliest...Full Text

Swift Observations of GRB 080607

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).

The robotic 0.6m Super-LOTIS telescope began R-band observations of the error region of GRB 080701A at 10:14:25 UT, 49 seconds after the trigger. Initial 10 and 20 second exposures reveal no sources other than those present in the relevant DSS image. A stack of 30x60sec images reveals no source at the location of the XRT source (Stroh et al., GCN 7911), down to a 3-sigma limiting magnitude...Full Text

08/06/03 19:58:42 GMT

The 0.6m Super-LOTIS telescope began R-band observations of the error region of GRB 080603 at 11:19:04 UT. The OT detected by Gomboc et al. (GCN 7788) and Chornock et al. (GCN 7789) is not apparent in the initial images, but is clearly visible in subsequent images. Using a stack of 10 x 60sec images obtained between 11:22:44 -> 11:33:46, we estimate the magnitude of the source to be R=19...Full Text

Swift Observation of GRB 080319C

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).

Our RAPTOR telescopes responded to Swift trigger 306778 (Pagani et al., GCN 7442) at 12:26:30.66 UTC, 33.70 seconds after the trigger. We detect the optical counterpart initially reported by Li (GCN 7441). Our measurements are consistent with those reported by KAIT (GCN 7441 and GCN 7475) and Super-LOTIS (7443). Our images became dominated by the morning twilight at about 12:35 UTC. ...Full Text

We observed the field of GRB 080315 starting at UT=02:43:58 (~19min since GRB) with the 2.3m Bok telescope at Kitt Peak, AZ. We obtained 23 x 60-sec and 7 x 120-sec images in the R-band filter. We do not detect emission at the location of the faint XRT source (Palmer et al., GCN 7416) to a limiting magnitude of R~23.5.
