N2 - On 2004 December 27, magnetar SGR 1806-20 emitted the brightest
Gamma-ray flare ever observed, outshining the entire Milky Way for a
fraction of a second. This flare also created a radio nebula, which is
believed to have been produced by material ejected from the surface of
the neutron star. Using a suite of radio telescopes, we have been
measuring the flux, growth, and proper motion of this source for the
past year, allowing us to measure the spectrum and shape of this object,
derive estimates of the initial mass and energy, and model the
interaction of this material with its environment. In this poster, we
present the most recent results from this campaign, as well as their
implications for the physical mechanism behind the 2004 Dec. 27 flare.
NRAO is a facility of the NSF operated under cooperative agreement by
AUI. The ATCA is funded by the Commonwealth of Australia foroperation as
a National Facility managed by CSIRO.
