TITLE: GCN CIRCULAR NUMBER: 15801 SUBJECT: GRB 140206A: Optical Observations via Virtual Telescope DATE: 14/02/06 22:21:53 GMT FROM: Gianluca Masi at Bellatrix Astronomical Obs G. Masi (Ceccano, Italy) and F. Nocentini (Frosinone, Italy) report: On Feb. 6.9216 2014 UT, we imaged the field around GRB 140206A (Lien et. al GCN 15784 , Gotz et. al GCN 15784) remotely using the the 0.43m-f/6.8 robotic unit part of the Virtual Telescope robotic facility in Italy. The source is visible on 300 seconds unfiltered CCD images at the following coordinates (J2000.0): R.A. = 09 41 20.23 Decl. +66 45 38.5 We also performed photometry, assuming R-mags from UCAC-4 for the stars in the field, getting an estimate for the magnitude of 18.9CR). Observations are ongoing. This message can be cited
