Zehnder, on behalf of the RHESSI GRB team, report: Ulysses, Mars Odyssey-HEND, RHESSI, HETE-FREGATE, and Konus-Wind observed this GRB at 19804 seconds. As observed by Ulysses, it had a duration of approximately 0.3 seconds, a 25-100 keV fluence of approximately 2E-07 erg/cm2, and a peak flux of approximately 8E-07 erg/cm2 s over 0.25 seconds. We have triangulated it a preliminary, 3 sigma error boxes with approximate area 9 square arcminutes whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 8 h 7 m 46.09 s 21 o 14 ' 17.73 " (CENTER) ERROR BOX CORNER 1: 8 h 7 m 45.73 s 21 o 12 ' 40.07 " (CORNER) ERROR BOX CORNER 2: 8 h 7 m 56.62 s 21 o 11 ' 40.15 " (CORNER) ERROR BOX CORNER 3: 8 h 7 m 35.56 s 21 o 16 ' 55.47 " (CORNER) ERROR BOX CORNER 4: 8 h 7 m 46.46 s 21 o 15 ' 55.39 " (CORNER) A Chandra NRA-accepted target of opportunity observation of this error box is being requested.

Berná (Univ. de Alicante) on behalf of the BOOTES team, report: "We have obtained several unfiltred exposures (45-s each) under good metereological conditions covering the short/hard GRB 021201 IPN error box (Hurley et al. GCN 1719). The images covered the period 05:28:23 - 05:32:12 UT 1 Dec 2002 (i.e. between 1.68-minutes before the trigger and 2.12-minutes after the trigger) with the very wide-field camera of BOOTES-1 (http://www.laeff.esa.es/BOOTES). After a visual inspection of the IPN error box (Hurley et al., GCN 1719) in all frames, we do not find evidence of optical emission, in particular simultaneously to the burst itself, for which we have an image covering the time interval 05:29:55 - 05:30:40 UT. Therefore we derive an upper limit of R = 10 for any optical counterpart simultaneous to this short/hard GRB. To our knowledge, this is the second short/hard GRB for which simultaneous images are available, following GRB 020531 (Castro-Tirado et al. 2002, GCN 1430). See also Castro-Tirado et al. 2002(A&A 393, L55) regarding this issue."

Henden at USNO/USRA A. Henden (USRA/USNO) reports on behalf of the USNO GRB team: We have acquired shallow BVRcIc all-sky photometry for a 20x20 arcmin field centered at the IPN coordinates for GRB021201 (Hurley et al., GCN 1719) with the USNOFS 1.0-m telescope on one photometric night. Stars brighter than V=13.0 are saturated and should be used with care. We have placed the photometric data on our anonymous ftp site: ftp://ftp.nofs.navy.mil/pub/outgoing/aah/grb/grb021201.dat The astrometry in this file is based on linear plate solutions with respect to UCAC2. The external errors are less than 100mas. If an afterglow is discovered, we will extend this calibration with additional nights to ensure against a systematic zeropoint error, and to include U-band measures. You should check the dates on the .dat file prior to final publication to get the latest photometry. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1741 SUBJECT: Chandra observation of the IPN error box of GRB021201 (short/hard) DATE: 02/12/12 21:34:59 GMT FROM: Kevin Hurley at UCBerkeley/SSL K.

Atteia, on behalf of the Chandra target of opportunity for IPN short bursts collaboration, report: Chandra observed the error box of the short/hard GRB021201 (GCN 1719) for approximately 21 ks starting at 23:10 on December 9. A very preliminary analysis indicates that about 26 sources are present in the Chandra field. They are listed in the table below. One of these sources (#10) is inside the IPN error box. A map has been posted at ssl.berkeley.edu/ipn3/021201. A second follow-up Chandra observation will take place in several weeks to determine whether this or any other source in the field displays fading behavior.

López-Corredoira (IAC, La Laguna) report: "On Dec 4.16 UT we observed the field of the short /hard GRB 021201 (GCN 1719) with the 2.5-m Nordic Optical Telescope (+ALFOSC) at the Observatorio del Roque de los Muchachos, in order to monitor the entire IPN error box. In the co-added image (5 x 900-s in the r' Sloan filter with a 2".8 seeing), no optical transient is found when comparing to the DSS-2 (R-band). Particularly, a point-like optical source with R about 20.5 is found at coordinates RA(2000) = 08 07 49.35, Dec(2000) = +21 12 33.8 (+/- 0".5); this is within 2" of the Chandra source # 10 reported to be inside the IPN error box (GCN 1741). Such object is visible in the blue and red DSS-2 charts as a very blue source that does not seem to be related to the GRB 021201. Further observations are planned."

Garnavich and J. Quinn (University of Notre Dame) We observed the entire error box of the GRB 021201 burst (GCN 1719) with the NOAO WIYN telescope on 2002 Dec. 5.5 (UT). The 3x600s R-band images were taken in 1.2" seeing. We confirm the presence of a bright optical source near the Chandra x-ray source #10 (GCN 1741) identified by Castro Cerón et al. (GCN 1743). The optical source is USNO-A2.0 1050.05586294 listed in the catalog at 08:07:49.350 +21:12:33.66 (J2000) and R=18.9. We estimate the brightness at R=20.4 using a zero point from a nearby Landolt standard star field. To search for fainter objects, we subtracted a PSF scaled to the peak of the USNO star and found no other sources brighter than R=23.3 within 4" of the Chandra #10 x-ray position. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1760 SUBJECT: GRB 021201: Optical Observations DATE: 02/12/16 21:27:18 GMT FROM: Melissa Nysewander at UNC,Chapel Hill M. Nysewander, J. Moran, L. Johnson, D. Moschler, D. Reichart (University of North Carolina), and A. Henden (USRA/USNO) report on behalf of a larger collaboration: We observed 100% of the ~9 square arcminute error box of the short-duration burst GRB 021201 (GCN 1719) with the 0.6-meter Morehead Observatory telescope beginning 2.1 days after the burst (GCN 1721) and with the 1.0-meter USNO telescope beginning 2.9 days after the burst. Both observations were made without filter and the second observation goes significantly deeper than the first. Visual comparison of the first and second epoch images reveals no transient sources to the limiting magnitude of the first epoch image, which we measure to be Rc = 21.2 mag (3 sigma), 21.6 mag (2 sigma), and 22.4 mag (1 sigma) using the field calibration of Henden (GCN 1723). Three Chandra sources lie in the field of view of the first epoch image and 20 Chandra sources lie in the field of view of the second epoch image. Visual comparison of the first and second epoch images and the DSS-2 (Red) reveals no obvious transient sources.
