"We have examined the variable optical sources reported by Rol et al. 
(GCN #955) in our NOT images taken on Feb 16.24 UT (GCN #949). We report 
the following preliminary magnitudes assuming R = 18.4 for the USNO-A2.0 
catalog star U1350_09300715 (GCN #955).

  ===========================================
   Object 1  Feb 16.24   R      22.88 +-0.22
   Object 2  Feb 16.24   R      23.01 +-0.22

These values are consistent with the magnitudes found on Feb 15.26 (GCN #955)."
