D. M. Smith, J. McTiernan, R. Schwartz, W. Hajdas,
and A. Zehnder, on behalf of the RHESSI GRB team, report:

A long-duration, bright GRB 141215A has been observed by Fermi (GBM 
trigger 440342778), Konus-Wind, INTEGRAL (SPI-ACS), Mars-Odyssey (HEND), 
RHESSI, and Swift (BAT), so far, at about 48376 s UT (13:26:16). The 
burst was outside the coded field of view of the BAT.

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
    ---------------------------------------------
     RA(2000), deg                 Dec(2000), deg
    ---------------------------------------------
    Center:
     179.056 (11h 56m 13s) -52.745 (-52d 44' 44")
    Corners:
     179.620 (11h 58m 29s) -52.523 (-52d 31' 22")
     178.533 (11h 54m 08s) -53.178 (-53d 10' 40")
     178.486 (11h 53m 57s) -52.965 (-52d 57' 53")
     179.570 (11h 58m 17s) -52.309 (-52d 18' 31")
    ---------------------------------------------
The error box area is 575 sq. arcmin, and its maximum
dimension is 1.1 deg (the minimum one is 10 arcmin).
The Sun distance was 68 deg.

This box may be improved.

The time history and spectrum will be given in forthcoming GCN Circulars.
