team, report:
The GRB 110213B discovered and localized by MAXI/GSC (Negoro et al., GCN
11716) was detected by Konus-Wind in the waiting mode at T0(KW)=52293 s
UT (14:31:33).
The burst light curve shows a single pulse with a duration of ~50 s.
As observed by Konus-Wind, the burst had a fluence of (1.77 +/-
0.16)x10^-5 erg/cm2 (in the 20 - 1400 keV range).
Modeling the K-W 3-channel time-integrated spectrum (from T0 to
T0+50 s) by a power law with exponential cutoff model:
dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep)
yields alpha = -1.52 +/- 0.25, and Ep = 123 +/- 19 keV.
All the quoted errors are estimated at the 1 sigma confidence level.
The K-W light curve of this burst is available at
