GRB041006 (= H3570): Chandra Observations In Progress G. Ricker, N. Butler, P. Ford, H. Marshall, R. Vanderspek (MIT); G. Garmire (PSU); and D. Lamb (U. Chicago), on behalf of a Chandra GRB ToO Team, write: Chandra grating spectrometer observations of the afterglow counterpart (Da Costa, Noel, and Price; GCN2765) for GRB041006 -- a bright, X-ray rich gamma-ray burst discovered by HETE (= H3570: Galassi et al, GCN 2770) -- are in progress. The Chandra LETG/ACIS observation commenced at approximately 5:30 UT on 7 October 2004, and will continue for approximately 26 hours. The scheduling of contemporaneous photometry and spectroscopy at other wavelengths is strongly encouraged. We are grateful to Harvey Tananbaum and the Chandra X-ray Center observatory staff for scheduling this observation to commence only 17 hours after the GRB event. This message may be cited.
