    An H2O flare in W49N

    We monitored the 22-GHz water vapor emission from W49N using a single VLBA antenna on intervals of a few days to about a week from December 1989 through May 1990. During this period, a strong flare occurred in...

    A monitoring program of interstellar OH and H2O masers

    We obtained spectra of a set of interstellar-OH and H2O masers at intervals of a few days to about a week throughout a period of about 5 months. The purpose was to determine whether interstellar scintillation and...

    Low frequency propagation in the Earth's magnetosphere

    Our principal conclusion is that large orbital radii will be required for imaging at 1.5 MHz. The minimum radius has not been determined, but it is at least 2.5R⊕ under conditions of solar maximum. Successful ima...

    Far Infrared Polarization of Dust Clouds

    The recently observed 10µ polarization of the Orion Nebula and the Galactic Center suggests that far infrared polarization may be found in these objects. Estimates are made of the degree of far infrared polari...
