report:
     
At 13:11:23 UTC on April 2, 2006 HETE-2 detected another long, bright and
soft event coming from the same position as H4043(="GRB060331"). 

Ground analysis yields an error box with the following corners:

R.A. =  233.7856 deg. ; Dec. = -15.4384 deg.
     =  15h35m09s     ;      = -15o26'18"

R.A. =  233.3906 deg. ; Dec. = -15.5543 deg.
     =  15h33m34s     ;      = -15o33'15"

R.A. =  233.3972 deg. ; Dec. = -15.6477 deg.
     =  15h33m36s     ;      = -15o38'51"

R.A. =  233.7922 deg. ; Dec. = -15.5313 deg.
     =  15h35m10s     ;      = -15o31'52"


This position is consistent with the position of event H4043 (Fenimore et
al., GCN 4938). It is  therefore unlikely that either H4043 or H4044 were
due to cosmic gamma ray bursts.
