Bissaldi et al. (GCN Circ. 15714) reported the GRB detection. Starting at 06:18:37.94 on January 10th, 2014, Fermi LAT detected high energy emission from GRB 140110A, which was also detected by Fermi-GBM (trigger 411027520). Table 1 contains the best reported positions from Swift.
Xu (GCN Circ. 15719) reported the detection with UVOT of an optical afterglow. Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.
BAT did not observe this burst.
XRT results are not available.
The Swift/UVOT observed the error circle of the Fermi/LAT GRB 140110A (Bissaldi et al., GCN Circ. 15714) in a series of u band observations tiled on the sky (Oates and Stamatikos GCN Circ. 15724). The total exposure time is 12.7 ks spread over 7 fields; each field was observed typically for 1.8 ks. Table 3 gives preliminary magnitudes using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc., 1358, 373). No correction has been made for the expected extinction in the Milky Way corresponding to a reddening of EB-V of 0.01 mag. in the direction of the GRB (Schlegel et al. 1998).
