Proposal Abstract
We resubmit the proposal to observe at 5 GHz the highly variable
BL Lac object 0524+034 detected recently with the \mbox{RATAN--600}
radio telescope. The new version of this proposal emphasizes the 15 GHz
VLBA image of this source as suggested by the review of our original
proposal. The high degree of broad band variability with the
characteristic scale of 10 days and shorter (possibly, as short as
IDV), the inverted spectrum and the available ground-based VLBI images
provide strong evidence on the existence of sub-mas component(s)
suitable for VSOP imaging. It is the Space VLBI (VSOP) resolution at
5 GHz which is needed to explore the jet components, which have steep
spectrum and are too faint at shorter wavelengths. The two-epoch
experiment proposed here is aimed at providing critical observational
data for an examination of the circumnuclear environment in and
propagation medium toward the source.

(compressed post-script, typically 50kbytes) can
be retrieved. Note that some 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 AO5 proposals were submitted in February 2001,
and information such as affiliations and contact details has
changed for some proposers since that time.
