Abstract (from CDS):

Here we report results of an INTEGRAL-AO1 observation of the X-ray burst and atoll source Ser X-1 performed in May 2003. The object was observed for a total on-source time of 400ks but nearly 8° off-axis due to its amalgamation with an observation of SS 433, the pointing target source. Ser X-1 has been clearly detected up to 30keV with unprecedented positional accuracy for high-energy emission. The 20-30keV light curve showed substantial variability during the observation. Comparison with previous observations indicates that the source was in its high (``banana'') state and displayed a soft spectrum during the INTEGRAL pointing. A (non simultaneous) radio-to-γ-rays broad-band spectral energy distribution is also presented for the first time and discussed.
