TENMA Observations of Hercules X-1
Abstract
Y. Tanaka, Institute of Space and Astronautical Science, Tokyo, telexes: " The Japanese x-ray-astronomy satellite Tenma (cf. IAUC 3787) will observe Her X-1 from about May 22 through early June. Using the 0.064 m**2 gas scintillation proportional counter array, Tenma will make both timing and detailed spectral observations as a function of pulse phase. Correlated optical observations of Her X-1 would be useful and desirable. Optical astronomers who are interested in collaborating are invited to contact me (telex Japan 24550 SPACETKY J) for a detailed schedule."
