IUE (International Ultraviolet Explorer) performed UV spectrophotometry at resolutions of 0.2 and 6 Angstroms from 1150 to 3350 Angstroms, acquiring more than 104000 spectra of some 9600 objects.
The Optical Monitoring Camera (OMC) observes the optical emission from the prime targets of the gamma-ray instruments on-board the ESA mission INTEGRAL (launched on Oct. 17, 2002). OMC has also the capability to monitor serendipitously a large number of optically variable sources within its field of view.
