The Be/X-ray binary 1A 0535+262 was discovered in 1975 during a giantoutburst. Afterwards it has shown periods of quiescence (flux below 10 mCrab),normal outbursts (10 mCrab-1Crab) and occasionally giant outbursts (severalCrab). Ending 11 years of quiescence, the last giant outburst took place inMay/June 2005, but the source was too close to the Sun to be observed by mostsatellites. A subsequent normal outburst took place in August 2005, which wasobserved by INTEGRAL and RXTE TOO observations. Based on INTEGRAL data, wepresent results on the long term pulse period history of the source, on theirenergy dependent pulse profiles and on phase resolved spectra.
