S. R. Oates (MSSL-UCL) reports on behalf of the Swift/UVOT team:
The Swift/UVOT began observerving the field of Swift BAT Slew
Survey (BATSS) GRB 100115A (Cummings et al. GCN Circ. 10325) 40ks
after the BAT trigger. We do not detect any source at the candidate
Swift XRT position (Margutti et al. GCN Circ. 10326).
The 3 sigma upper limits for the summed images are reported below:

The above magnitudes are not corrected for the Galactic extinction
corresponding to a reddening of E_{B-V} = 0.06 mag (Schlegel et al.,
1998, ApJS, 500, 525). The photometry is on the UVOT photometric system
described in Poole et al. (2008, MNRAS, 383,627).
