The long-duration GRB 241114B 
(Insight-HXMT-HE detection: Wang et al., GCN 38284

; 
IPN triangulation: Svinkin et al., GCN 38341

) 
triggered Konus-Wind at T0=39903.659 s UT (11:05:03.659). 
 
The burst light curve shows a multipeaked structure 
which starts at ~T0-11.7 s and has a total duration of ~45 s. 
The emission is seen up to ~2 MeV. 
 
The Konus-Wind light curve of this GRB is available at 
http://www.ioffe.ru/LEA/GRBs/GRB241114_T39903/ 
 
As observed by Konus-Wind, the burst 
had a fluence of 4.03(-0.38,+0.43)x10^-5 erg/cm2, 
and a 64-ms peak flux, measured from T0+23.648 s, 
of 1.38(-0.22,+0.24)x10^-5 erg/cm2/s 
(both in the 20 keV - 10 MeV energy range). 
 
The time-averaged spectrum of the burst 
(measured from T0 to T0+32.768 s) 
is best fit in the 20 keV - 16 MeV range 
by the GRB (Band) model with the following parameters: 
the low-energy photon index alpha = -1.15(-0.10,+0.11), 
the high energy photon index beta = -3.11(-6.89,+0.49), 
the peak energy Ep = 258(-25,+30) keV 
(chi2 = 123/97 dof). 
 
The spectrum near the maximum count rate 
(measured from T0+16.640 s to T0+24.576 s) 
is best fit in the 20 keV - 16 MeV range 
by the GRB (Band) model with the following parameters: 
the low-energy photon index alpha = -0.76(-0.14,+0.17), 
the high energy photon index beta = -3.08(-6.92,+0.46), 
the peak energy Ep = 272(-30,+31) keV 
(chi2 = 84/77 dof). 
 
All the quoted errors are at the 90% confidence level. 
All the quoted values are preliminary.
