M.G. Bernardini (INAF-OAB) for the Swift team
At 12:46:59 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 200701A (trigger=980421) (Bernardini et al. GCN Circ. 28052). Swift did not slew immediately due to a Sun observing constraint. At the time of the trigger, the initial BAT position was 44° from the Sun (1.5 hours East) and 102° from the 84%-illuminated Moon. Table 1 contains the best reported positions from Swift.
Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.

As reported by Sakamoto et al. (GCN Circ. 28054),
the BAT ground-calculated position is RA, Dec = 123.563, -14.553 deg which is RA(J2000) = 0
The mask-weighted light curve (Figure 1) shows a single-pulse structure that starts at ~T-7 s and peaks at ~
The time-averaged spectrum from T-6.81 to T+42.17 s is best fit by a simple power-law model.
The power law index of the time-averaged spectrum is 1.91 ± 0.16.
The fluence in the 15-150 keV band is 9.3 ± 1.0 x 1
The results of the batgrbproduct analysis are available at https://gcn.gsfc.nasa.gov/notices_s/980421/BA/.
XRT refined results are not available.
UVOT results are not available.
