H 1743-32
K. Wood, G. Share, N. Johnson, D. Yentis, E. Byram and their
HEAO A1 collaborators, Naval Research Laboratory, report the
detection of an x-ray source whose position is consistent with the
transient H 1743-32 (cf. IAUC 3106, 3113). The source was observed on
Mar. 12-18 and had a 1-10-keV intensity of ~ 10**-9 erg cm**-2 s**-1, an
order of magnitude below its peak intensity observed in Sept. 1977.
