About Tenma

Tenma (Astro-B; launched Feb 20, 1983) was Japan's second X-ray satellite following its predecessor Hakucho (launched in 1979). Tenma carried sensitive scintillation proportional counters (SPC), with which X-ray spectroscopy of many Galactic and extra Galactic sources have been carried out. Tenma reentered atmosphere ion January 19, 1989.

Tenma raw telemetry data are archived at ISAS in the SIRIUS database system. At DARTS, we archive observation log of Tenma. Data processing software and analysis software have not been archived, so we may not support scientific data analysis of Tenma.
