P. Minaev (IKI) and A. Pozanenko (IKI)  report on behalf of larger GRB 
follow-up collaboration:

We analyzed GRB 201015A detected by Swift (D'Elia et al., GCN 28632) 
using GBM/Fermi spectral data  (Fletcher et al., GCN 28663) and redshift 
of z = 0.426 (de Ugarte Postigo et al., GCN 28649; Izzo et al., GCN 
28661). GRB 201015A has a low luminosity, Eiso = (1.1 +/- 0.2)*10^50 
erg, and well consistent with the Ep,i ��� Eiso correlation (Amati 
relation) for type II (long) bursts, see [1] for details and Figure at

The position of the burst is within 1-sigma confidence area of the 
cluster of type II (long) bursts on the EH ��� T90,i diagram (see [2] for 
details), indicating strong association with type II bursts, see Figure at

We encourage follow-up optical observations to search for associated
