//////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1870 SUBJECT: IPN triangulation of GRB030217 (annulus) DATE: 03/02/17 21:46:20 GMT FROM: Kevin Hurley at UCBerkeley/SSL K.

Galassi, T. Tavenner, T. Donaghy, M. Boer, J-F Olive, and J-P Dezalay, on behalf of the HETE GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: Ulysses, HETE-FREGATE, and INTEGRAL (SPI-ACS) observed this GRB at 09942 seconds. As observed by Ulysses, it had a duration of approximately 50 seconds, a 25-100 keV fluence of approximately 1.2E-05 erg/cm2, and a peak flux of approximately 1.2E-06 erg/cm2 s over 0.50 seconds. We have triangulated it to a preliminary annulus centered at RA, Decl(2000)= 171.644, +41.752 degrees, whose radius is 55.349 +/- 0.035 degrees (3 sigma ). This annulus may be constrained and/or improved, but it is not known at this point whether this event was observed by Mars Odyssey, and thus whether a small error box can be derived for it. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1872 SUBJECT: IPN triangulation of GRB030217 (small error box) DATE: 03/02/19 18:16:10 GMT FROM: Kevin Hurley at UCBerkeley/SSL K.

We have triangulated it to a preliminary, 3 sigma error box with approximate area 68 square arcminutes whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 12 h 26 m 22.80 s -11 o 51 ' 24.23 " ERROR BOX CORNER 1: 12 h 26 m 30.37 s -11 o 53 ' 08.09 " ERROR BOX CORNER 2: 12 h 25 m 27.01 s -11 o 56 ' 50.21 " ERROR BOX CORNER 3: 12 h 27 m 18.75 s -11 o 45 ' 54.28 " ERROR BOX CORNER 4: 12 h 26 m 15.24 s -11 o 49 ' 40.33 " This error box may be improved. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1873 SUBJECT: GRB030217: optical observations DATE: 03/02/20 17:32:13 GMT FROM: Adriano Guarnieri at O.A.di Bologna A. Guarnieri, S.Bernabei, C.Bartolini, A.Piccioni, I.Bruni, (Bologna University and Bologna Astronomical Observatory), and G. Pizzichini (IASF-CNR, Sezione di Bologna) report: On 2003, February 20, 00h38m23s UT we started observations of the error box of GRB030217 (GCN 1872) with the 152 cm telescope in Loiano, (R band, 300 sec exposures). Coverage of the entire error box was performed in bright sky conditions because of the full moon. By comparison with the DssII, in our frames there is no new source brighter than 18.0 mag.

T. Holland, P. M. Garnavich (Notre Dame), A. Hornstrup (Danish Space Research Institute), Barbara Mochejska, K. Z. Stanek (Harvard-Smithsonian CfA), and H. Pedersen (Copenhagen) report We have obtained Rc-band images of most of the IPN error region for GRB 030217 (GCN 1872) using the 2.56-meter Nordic Optical Telescope on La Palma on 2003 Feb. 22 UT, and using the Fred Lawrence Whipple Observatory 1.2m telescope on Mt Hopkins, Arizona on 2003 Feb. 20, 21 and 22 UT. Our data cover approximately 80% of the IPN error region and are centred on the centre of the error region. No optical afterglow is visible in our images to the detection limit of the second generation Digital Sky Survey. The galaxy LCRS B122355.6-113041 is located at R.A. = 12:26:30.91, Dec. = -11:47:17.3 (J2000), which is just outside the northeast edge of the IPN error region. This galaxy has a magnitude of 17 and a redshift of 0.14 (Shectman et al., 1996, ApJ, 470, 172). We find no evidence for a variable source in or near this galaxy, but we urge observers with earlier data to check for a possible transient near this location. This message may be cited.
