Description the astrophysical nature of the hard x-ray source grs 1915+105 is unknown. recent observations in the radio and near infrared wavelengths have led to the identification of a counterpart at those energies. it is likely that grs 1915+105 may also be identical with the soft gamma-ray repeater sgr 1900+14 showing recent activities. in addition, co measurements indicate the presence of two molecular clouds, one of which being a good candidate for a possible association with the grs 1915+105. the source shows strong variability (partially correlated) in radio, near ir and hard x-rays including strong outbursts. this observational evidence could be explained by a scenario in which a possible black hole is fed by accretion from giant molecular clouds and the observed variability and bursts might be due to thermal instabilities during accretion. in case grs1915+105 will undergo a new outburst at other wavelengths (including new soft gamma-ray repeating events (as reported e.g. from the batse experiment onboard gro)) immediate follow-up observations in the ir shall be conducted in form of a too observation. the investigations of the ir quiescent counterpart are subject of a second independent proposal.

Mission Description The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
