Description
We report time-resolved photometry of the optical counterpart to the
black hole candidate SWIFT J1753.5-0127 (Palmer et al. 2005, ATel #546:
Halpern et al. 2005, ATel #549). After its discovery, this source has
remained in the low/hard state and bright at optical/IR wavelengths.
Our analysis indicates that this X-ray transient is a short orbital
period X-ray binary. We obtained time-series photometry on 2007
Jun 3, 4, 5, 7 and 8 UT with the 1.5-m telescope and from 2007 Jun 27
to Jul 1 UT with the 0.84-m telescope, both at the Mexican Observatorio
de San Pedro Martir.
