GRB 210704A was initially reported by \nX-/gamma-ray experiments (Ursi et al., GCN 30372; Berretta et al., GCN \n30375; Prasad et al., GCN 30378; D'Ai et al., GCN 30379; Malacaria et \nal., GCN 30380; Ridnaia et al., GCN 30388). The burst was detected by \nSPI-ACS at (UTC) 2021-07-04T19:33:24.5. Its duration in the SPI-ACS \nenergy band (> 80 keV) is T_90 = 3.5 +/- 0.7 s. Comparing fluences of \nlong-duration GRBs simultaneously recorded by SPI-ACS and Fermi/GBM \n(Chelovekov et al., in preparation) we estimated the GRB 210704A fluence \nto be 1.8e-5 erg/cm^2 in the 10-1000 keV band (the 95% confidence region \nwhich includes systematics was 5.2e-6 ��� 6.3e-5 erg/cm^2).  We did not \ndetect any signature of an extended emission in the SPI-ACS energy band \n(> 80 keV). GRB 210704A was also detected by ISGRI detector as 106 \ndegrees off-axis event.  The light curve of both SPI-ACS and ISGRI can \nbe found at\n\nhttp://grb.rssi.ru/GRB210704A/GRB20210704A_ISGRI_ACS.png",
