Ulysses, INTEGRAL (SPI-ACS), RHESSI, and HETE have observed
two events whose arrival directions are consistent with that
of SGR1806-20:

DATE	UT	ANNULUS	 ANNULUS    ANNULUS    deltaR	DISTANCE  DURATION  PEAK FLUX  FLUENCE  SPACECRAFT  
        S.	RA(2000) DEC(2000)  RADIUS    (3 SIGMA)  DEG.	   S.       erg/cm2s   erg/cm2
030712 76693.0  335.440 -27.794     57.625     0.017    0.003     0.180     5E-6       4E-6	ULYSSES, RHESSI, INTEGRAL
030713 77470.8  335.566 -27.667	    57.749     0.017    0.0001    0.032     1E-6       1E-7     ULYSSES, HETE(2763)

The annulus half-width is deltaR; distance is the angular distance between the centerline
of the annulus and the position of SGR1806-20; duration is the duration as observed
by Ulysses; peak fluxes and fluences are as observed by Ulysses, and are over 0.03125 s, 
and 25-100 keV.
