Proposal Abstract

We propose high resolution observations of a sample of radio sources monitored by the Green Bank interferometer. Over 160 sources are monitored daily by the Green Bank Interferometer, following the long term variations of these sources at S and X band. For a few sources, the percentage variation at X band is much greater than at S band. Most notable of these sources is 1413+135, which is 17 times more variable at X band than S band. 1413+135 is possibly a gravitational lens system, but as yet, there is no explanation for this remarkable variability. We have selected a sample of 4 bright radio sources which are more than 5 times more variable at X band than S band. We propose 5. GHz observations with VSOP + VLBA + GB 140' for this sample.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that many proposals were reduced in extent by the Scientific Review Committee (e.g. by reducing the number of experiments), however the Cover Sheets contain the full proposal as submitted. Also note that AO1 proposals were submitted in November 1995, and information such as affiliations and contact details has changed for some proposers since that time. The Cover Sheets (and the details on this page, which were derived from the Cover Sheets) may therefore have changed.
