The high visual brightness of the planet completely saturates the IUE acquisition monitor (fine error sensor, FES) so that it is not possible to point at and track Venus in the conventional manner. ...Type of Medium: Electronic ResourceURL: -

The visual appearance of the comet was diffuse with a weak central condensation and with only a slight trace of an ion tail. The comet could be tracked on its centre of ...Type of Medium: Electronic ResourceURL: -

In comet West (1976 VI), the observed C I emission was consistent with a model of carbon as a daugher of CO which is vaporized from the nucleus as a parent molecule3. However, for comet ...Type of Medium: Electronic ResourceURL: -
