report on behalf of the MAXI team:
Swift-XRT performed 7 tiled followup observations for GRB 190714A (Serino et al. GCN 25068;
Evans GCN 25069) on July 14th, 2019 (from T0 +7.9 ks to T0 +9.3 ks).
We conclude that GRB 190714A is not a GRB, but very likely to be an X-ray flare from
the M (or dMe) star 2E 1624.6+1504/UCAC4 525-061488 (for detail, see Negoro et al. ATel #12944).
