摘要：

We have conducted an extensive observational campaign of SWIFT J1753.5-0127 over the last year, since its bright our-burst episode in 2005. Using long time baseline optical photometry, we have found a new period suggestive of orbital modulation with a period of 3.2 h, we have simultaneous multi-band photometry, and high-frequency multi-band photometry from ULTRACAM. In the latter data, we find evidence for a broad quasi-periodic oscillation in the g' and r' bands centred on a period of similar to 25 s and a narrower one of period similar to 12 s.
