We observed the field of EP260214a (Li et al., GCN 43742Loading...
 
 ) with the HAWKI imager on the ESO VLT UT4 (Yepun). Observations began at ~11.9 hr after the EP/WXT trigger and were carried out at an average airmass of about 1.0 in the J filter.

Several extended sources are visible close to or within the EP/FXT error region (Li et al., GCN 43751Loading...
 
 ), however no uncatalogued source is clearly identified in our observations down to a 3 sigma limiting magnitude J~25 AB mag calibrated using nearby stars in the 2MASS Catalogue (Skrutskie et al. 2006) and not corrected for Galactic extinction.

We thank the staff at the VLT, for the rapid execution of these observations.
