R. Ruffini, L. Izzo, A. Penacchione, S.K. Chakrabarti on behalf of ICRAnet
reports:

We have tentatively identified the redshift factor z of GRB 101023A (GCN
11363, 11364, 11365, 11366) to be between 0.7 to 1.0 from Amati relation. This
GRB had two major pulses whose E_iso appear to be ~1052 ergs and ~2x1053 ergs
respectively. Despite being bright and nearby, no Supernovae has been reported
for this source. We encourage anyone having data especially around 1st to 7th
of November, 2010, on this object on supernovae association (either way) to
report them to facilitate understanding this object.
