**Long** GRB detected by Swift (GCN 40894, 40928, T90 s in the 15 - 150 keV) and **Fermi GBM** (GCN 40892, 40927 T90 54 s in the 50- 300 keV) and **Konus-Wind** (40948, T90 46 s in the 20 keV - 10 MeV). T0 refers to Swift BAT. Localization refers to **UVOT** (GCN 40894). X-ray counterpart with **Swift/XRT** (GCN 40902) and **EP** (GCN 40967). Optical follow-up with **Ondrejov D50** (GCN 40895) **GOTO** (GCN 40894), **NOT** (GCN 40900),**COLIBRI**(GCN 40907), **DDOTI** (GCN 40911). **REM** (GCN 40913). **TRT**(GCN 40916). **Skynet** (GCN 40921), **AKO** (GCN 40925). **Skynet** V, R observations (GCN40921). **AKO** (GCN40925), **Leavitt** (GCN 40926), **Swift/UVOT**(GCN 40933). **SVOM/VT** (GCN 40936). **Konkoly** (GCN 40939), **GROWTH** (GCN 40946). **Monte Agliale** (GCN 40968), **Calapai** (GCN 40973). **GTC/Osiris** measured the redshift (GCN 40901). **GRANDMA** observed with **KNC** astronomers and with **TAROT** team (measurements are calibrated from Gaia). TAROT responded 1 min post T0 with TAROT/TCA (GCN 40969).
