We report the detection of a Fast Radio Burst (FRB) with the Australian Square Kilometre Array Pathfinder (ASKAP), as part of the Commensal Real Time Fast Transient (CRAFT) survey science project. The burst, FRB 190711, was detected with a reported signal to noise ratio of 24 in the incoherent sum of intensities from 29 antennas. The system was operating with a central frequency of 1272.5 MHz, an observing bandwidth of 336 MHz, and time resolution of 1.7 ms. The pulse duration (full width at half maximum) is approximately 9 ms.
A preliminary localization using the multi beam approach described in Bannister et al. (2017, ApJL, 841,12). The properties of the burst are as follows:
Date: 2019-07-11.07894784
RA (J2000): 21:56(3)
DEC (J2000): -80:23(6)
DM: 593(2) pc cm^-3
Fluence: 28(4) Jy ms
Quoted uncertainties are with 90% confidence.
