At 14:44:47 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 080916B (trigger=324907). The BAT on-board calculated location is
RA, Dec 163.624, +69.044 which is
RA(J2000) = 10h 54m 30s
Dec(J2000) = +69d 02' 39"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve showed a multi-peaked
structure with a duration of about 50 sec. The peak count rate
was ~750 counts/sec (15-350 keV), at ~0 sec after the trigger.

there is a strong 8.4 sigma excess detected in the scaled map image,
which strongly suggests a real gamma-ray burst occurred.

for the Swift-BAT and BATSS teams
At 01:10:41, Swift-BAT observed GRB 080702B. The burst occurred
during a preplanned Swift slew maneuver. The rate increase was
noted during a routine check of the counting rates for missed out-
of-field and slew bursts. A GRB candidate was automatically
detected by the BAT Slew Survey (BATSS) with 5.9 sigma in the
S band (15-50 keV) and 6.5 sigma in the B band (15-150keV).
The burst profile is FRED-like with ~3sec rise and ~30sec decay.
The peak count rate is 0.05cts/sec (S band) and 0.04cts/sec (B band).
BATSS automated analysis measured T90 = 10.5sec and T50 = 5.5sec,
and a position
RA = 23h 42m 24s, DEC = -05d 29' 23"
with a 90% confidence radius of 6.4arcmin.

error circle. No event data are yet available to determine the column
density using X-ray spectroscopy.

At 19:38:13 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 080603B (trigger=313087). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 176.528, +68.076 which is
RA(J2000) = 11h 46m 07s
Dec(J2000) = +68d 04' 33"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve shows three main peaks
with a duration of about 70 sec. The peak count rate
was ~8000 counts/sec (15-350 keV), at ~2 sec after the trigger.

At 01:30:28 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 080602 (trigger=312958). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 19.173, -9.251 which is
RA(J2000) = 01h 16m 41s
Dec(J2000) = -09d 15' 02"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve showed two well-separated
peaks with a total duration of about 70 sec. The peak count rate
was ~3000 counts/sec (15-350 keV), at ~60 sec after the trigger.
