M. De Pasquale (MSSL-UCL) & S. B. Cenko (GSFC) report on behalf of the
Swift team:
Swift/UVOT started observations of GRB140209A (Cenko et al., GCN Circ.
15808) 188.1
ks after the burst trigger.
No optical counterpart is detected at the position of XRT counterpart
(D'Elia et al.,
GCN Circ 15819) and the P60 Source (Perley et al., GCN Circ 15809) in summed
exposures.
Preliminary 3-sigma upper limit using the UVOT photometric system
(Breeveld et al al.
2011, AIP Conf. Proc. 1358, 373) is:
Filter T_start (s) T_stop (s) Exp(s) Mag
white 188075 195531 2689 >22.7
No correction has been made for the expected Galactic extinction
corresponding
to E(B-V) = 0.03 in the direction of the burst (Schlegel et al. 1998).
