GRB040912 (= H3557): Chandra Observations Scheduled
G. Ricker, P. Ford, N. Butler, R. Vanderspek (MIT), and D. Lamb (U.
Chicago), on behalf of a Chandra GRB ToO Team,
write:
Chandra target-of-opportunity observations of the entire HETE WXM
error circle for GRB040912 (= H3557: Butler et al, GCN 2701) have
been approved and scheduled, subject to possible high background
radiation constraints. The first epoch observation will commence near
22h UT on 15 September, with a second epoch observation ~1 week later.
As noted by Butler et al (GCN 2701), although GRB040912 exhibits the
spectral characteristics of an XRF, its temporal characteristics are
quite unusual. The scheduling of contemporaneous observations at
other wavelengths, especially deep initial and second epoch optical
and IR observations, is strongly encouraged.
We are grateful to Harvey Tananbaum and Andrea Prestwich for
approving this DDT observation.
