COMET TAGO-SATO-KOSAKA (1969g)
Drs. A. D. Code, T. E. Houck and C. F. Lillie, Wasburn Observatory,
University of Wisconsin, report: "Comet 1969g has been observed
in the ultraviolet by the Orbiting Astronomical Observatory.
The Wisconsin ultraviolet photometers and spectrophotometers have
obtained data commencing January 14 14h21m UT. The head of the
comet is bright in L-alpha out to distances of 30' from the nucleus and
is measurable to a distance of approximately 1.5 deg. A strong feature,
presumably OH, is present at approximately 3070 A. A continuum
is present, reaching a minimum near 1900 A and increasing in
intensity again to 1100 A. Observations will continue through
January 30, and supporting ground-based data during this period will
be valuable."
PERIODS OF FOUR SOUTHERN PULSARS
M. M. Komesaroff, J. G. Ables, D. Morris, D. J. Cooke, U. J.
Schwarz and P. A. Hamilton, Radiophysics Division, CSIRO, Sydney,
write: "Improved periods (referred to the barycenter of the solar
system) have been determined at the Australian National Radio
Astronomy Observatory, Parkes, for four Molonglo pulsars. For
three of them the dispersion measures (pc cm**-3), and for two the
declinations, have been obtained with increased accuracy. Upper
limits on the (dimensionless) rate of change of period have been
determined in three cases."
