Groundbased Infrared Observations of Celestial Sources

Abstract

Reduction of the groundbased sky survey observations made at a wavelength of 10 micrometers has been continued. In order to increase the sensitivity and speed of the groundbased observations, extensive modifications to the 28 inch telescope have been made. A preliminary report on the results of these modifications is given. The absolute calibration of infrared photometry is of fundamental interest. As part of this program, extensive photometry is carried out at 10 and 20 micrometers on the nuclei of galaxies and quasars. More than 75 such objects have now been observed at flux levels on the order of 3 x 10 to the minus 19th power W/sq.cm./micrometer. These results are summarized. In addition, the results of photometry on a number of highly variable infrared stars which contribute to a fluctuating component of the sky background are reported.
