Source Notes:
This detection was announced by Wagner et al. on behalf of the H.E.S.S. Colaboration in an
ATel on 13 April 2020.
PKS 0903-57 had been reported to be in a flaring state in the high-energy regime by AGILE (
Lucarelli et al. 2020)
and by Fermi-LAT (
Buson et al. 2020) on 01 April 2020.
The H.E.S.S. obwervations took place on 13 April 2020 and the source was detected with a significance of more than 25 sigma
after 49 minutes of exposure.
