| Summary:
The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst
(CHIME/FRB) Project has a new VLBI Outrigger at the Green Bank Observatory
(GBO), which forms a 3300km baseline with CHIME operating at 400-800MHz. Using
100ms long full-array baseband "snapshots" collected commensally during FRB and
pulsar triggers, we perform a shallow, wide-area VLBI survey covering a
significant fraction of the Northern sky targeted at the positions of compact
sources from the Radio Fundamental Catalog. In addition, our survey contains
calibrators detected from two 1s long trial baseband snapshots for a deeper
survey with CHIME and GBO. In this paper, we present the largest catalog of
compact calibrators suitable for 30-milliarcsecond-scale VLBI observations at
sub-GHz frequencies to date. Our catalog consists of 200 total calibrators in
the Northern Hemisphere that are compact on 30-milliarcsecond scales with
fluxes above 100mJy. This calibrator grid will enable the precise localization
of hundreds of FRBs a year with CHIME/FRB-Outriggers.
