GRB 030102, GRB 030102A

GCN Circular 1793

Subject
IPN triangulation of GRB030102A - correction to peak flux
Date
2003-01-08T20:05:14Z (23 years ago)
From
Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu>
The peak flux for this burst should have read:
approximately 1.2E-6 erg/cm2 s over 0.5 seconds.

IPN triangulation of GRB030102A (large error box)

K. Hurley, on behalf of the Ulysses GRB team,

E. Mazets and S. Golenetskii, on behalf of the Konus-Wind GRB team, and

T. Cline, on behalf of the Ulysses and Konus GRB teams, report:

Ulysses and Konus-Wind  observed this GRB at 56870 seconds.
As observed by Ulysses, it had a duration of approximately  30 seconds, 
a 25-100 keV fluence of approximately  1.2E-05 erg/cm2, and a peak flux 
of approximately  5.0E-01 erg/cm2 s over 0.5 seconds.

We have triangulated it to a preliminary annulus centered  at RA, Decl(2000)=
181.922, 37.602 degrees, whose radius is 78.343 +/- .036 degrees (3 sigma ).

The Konus ecliptic latitude response constrains the arrival direction 
to a band between ecliptic latitudes 55 and 75 degrees, that is, to those 
portions of the annulus north of RA, Decl= 283, +32 degrees, and 2, +64 
degrees.

This annulus can be improved, but as the event was not observed by 
Mars Odyssey, a small error box cannot be derived for it.

Coronas-F -Wind triangulation of GRB030102

S.Golenetskii, V.Palshin, A.Kokomov, and D.Frederiks on behalf of
the Helicon/Coronas-F and Konus-Wind teams, and T.Cline on behalf of
the Konus-Wind team report:

Helicon instrument on board Coronas-F S/C detected this event at
23:18:59.108 UT (83939.108 s).
We have triangulated it with the Konus-Wind to a preliminary annulus
centered  at RA(2000) = 251.877, Decl(2000) = -23.586 degrees,
and Radius = 77.1 +/- 1.7 degrees (3 sigma).

Subject
IPN triangulation of GRB030102 (annulus)
Date

From
Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu>
K. Hurley and T. Cline, on behalf of the Ulysses GRB team, 

A. von Kienlin, G. Lichti, and A. Rau, on behalf of the
INTEGRAL SPI-ACS GRB team, and

D. M. Smith, R. P. Lin, J. McTiernan, R. Schwartz, C. Wigger, W. Hajdas, 
and A. Zehnder, on behalf of the RHESSI GRB team, report:

Ulysses and RHESSI also observed this burst (GCN 1786).  As observed by
Ulysses, it had a duration of approximately 5 seconds, a 25-100 keV
fluence of approximately  5.1E-06 erg/cm2, and a peak flux of
approximately  6.9E-07 erg/cm2 s over 0.50 seconds.

We have triangulated it to a preliminary annulus centered  at RA,
Decl(2000) = 2.023, -37.567 degrees, whose radius is 14.958 +/-  
0.144 degrees (3 sigma ).

This annulus may be constrained and/or improved. but as the event was
not observed by Mars Odyssey, a small error box cannot be derived for
it.
