U.Quadri, L.Strabla, R.Girelli and A.Quadri report:

We imaged the field of GRB 130418A (de Pasquale et al. 2013; GCN
Circ. 14377Loading...
 
 ) detected by SWIFT(trigger 553847) with the robotic 
telescope of (IAU station 565) Bassano Bresciano 
Observatory, Italy.

The observations started 15 min. after the 
GRB trigger,with our schmidt telescope 
D=400 mm F/D=3.

Weather conditions were discrete for moon presence.

We co-added 14 unfiltered CCD exposures of 120s each.

We detect a new source of 16.3 Vmag in the error box given by SWIFT.
We detected the candidate couterpart at the following position (+/- 2 arcsec):

RA (J2000.0) =  09h 56m 08.90s 
DEC(J2000.0) = +13�� 40' 02.8"

Magnitudes were estimated with the USNO-B1 cat. 
and are not corrected for galactic dust extinction.
