Proposals are invited for observations to be performed with the International Gamma-ray Astrophysics Laboratory (INTEGRAL) satellite. The gamma-ray observatory Integral is the second medium-sized mission of ESA's Horizon 2000 Science Programme. It is scheduled for launch in April 2002 and offers astronomers a unique opportunity to perform high-resolution spectroscopy in the energy range from 20 keV to 8 MeV (Spectrometer SPI) and high angular resolution imaging in the energy range from 15 keV to 10 MeV (Imager IBIS). Concurrent monitoring of high-energy sources will be performed by the co-aligned monitors in the 3 keV to 35 keV X-ray band (X-ray Monitor JEM-X) and in the optical wavelengths (V, 500-600 nm) by the Optical Monitoring Camera (OMC).

This announcement solicits proposals for observations to be carried out in the period from July 2002 to June 2003. Proposals should be prepared and submitted in electronic form (for details see http://astro.estec.esa.nl/Integral/isoc ). Deadline: February 16, 14:00 GMT.
