G. Di Cocco, F. Fuschino, M. Galli, C. Labanti, and M. Marisaldi, on
behalf of the AGILE MCAL team, report:

The short GRB 121011B has been observed so far by Konus-Wind,
INTEGRAL(SPI-ACS), Suzaku(WAM) and AGILE (MCAL) at about 81143 s UT
(22:32:23).

We have triangulated the burst to a preliminary, 3 sigma error box whose
coordinates are:
    ---------------------------------------------
     RA(2000), deg                 Dec(2000), deg
    ---------------------------------------------
    Center:
     182.809 (12h 11m 14s) +44.113 (+44d 06' 47")
    Corners:
     179.176 (11h 56m 42s) +41.963 (+41d 57' 48")
     178.172 (11h 52m 41s) +41.937 (+41d 56' 14")
     187.165 (12h 28m 40s) +46.167 (+46d 10' 01")
     188.461 (12h 33m 51s) +46.130 (+46d 07' 48")
    ---------------------------------------------
The error box area is 3.43 sq. deg, and its maximum
dimension is 8.49 deg (the minimum one is 0.75 deg).

This box can be improved.

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