26033 - ACRIMSAT

ACRIMSAT was an American satellite to ascertain the extent of solar radiation variability, and was launched by a Taurus rocket from Vandenberg AFB. It carried an ACRIM-3 (Active Cavity Radiometer Irradiance Monitor) instrument to monitor solar irradiance at high accuracy (<0.1%) as a long term followup to the ACRIM-2 (carried on UARS spacecraft since 1991) and ACRIM-1 (carried on the SMM spacecraft in 1980). Initial orbital parameters were period 99 min, apogee 727 km, perigee 683 km, and inclination 98.3 deg.
