  At 22:48:05 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060219 (trigger=191512). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 241.806,+32.330 deg {16h 07m 14s, +32d 19' 49"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a weak single peak with a duration of ~10 sec. The peak count rate was ~500 counts/sec (15-350 keV), at ~5 sec after the trigger.
  The XRT began taking data at 22:50:05 UT, 120 seconds after the BAT trigger. The XRT on-board centroid algorithm did not find a source in the image and no prompt position is available. The prompt spectrum and lightcurve are consistent with a weak, possibly fading source in the field of view. We are waiting for down-linked data to detect and determine a position for the source.
  UVOT took a finding chart exposure of 200 seconds with the V filter starting 121 seconds after the BAT trigger. No afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 25% of the BAT error circle. The typical 3-sigma upper limit has been about 18th mag. The 8'x8' region for the list of sources generated on-board covers 100% of the BAT error circle. The list of sources is typically complete to about 18.0 mag. No correction has been made for the expected extinction of about 0.1 magnitudes.

  Richard J. Cool (Arizona), Daniel J. Eisenstein (Arizona), David W. Hogg (NYU), Michael R. Blanton (NYU), David J. Schlegel (LBNL), J. Brinkmann (APO), Donald P. Schneider (PSU), and Daniel E. Vanden Berk (PSU) report:
  The Sloan Digital Sky Survey (SDSS) imaged the field of burst GRB060219 prior to the burst. As these data should be useful as a pre-burst comparison and for calibrating photometry, we are supplying the images and photometry measurements for this GRB field to the community.
  Data from the SDSS, including 5 FITS images, 3 JPGS, and 3 files of photometry and astrometry, are being placed at http://mizar.as.arizona.edu/~grb/public/GRB060219
  We supply FITS images in each of the 5 SDSS bands of a 8'x8' region centered on the GRB position (ra=241.806 (16:07:13.4), dec=32.3300 (32:19:48.0) GCN 4788), as well as 3 gri color-composite JPGs (with different stretches). The units in the FITS images are nanomaggies per pixel. A pixel is 0.396 arcsec on a side. A nanomaggie is a flux-density unit equal to 10^-9 of a magnitude 0 source or, to the extent that SDSS is an AB system, 3.631e-6 Jy. The FITS images have WCS astrometric information.
  In the file GRB060219_sdss.calstar.dat, we report photometry and astrometry of 520 bright stars (r<20.5) within 15' of the burst location. The magnitudes presented in this file are asinh magnitudes as are standard in the SDSS (Lupton 1999, AJ, 118, 1406). Beware that some of these stars are not well-detected in the u-band; use the errors and object flags to monitor data quality.
  In the files GRB060219_sdss.objects_flux.dat and GRB060219_sdss.objects_magnitudes.dat, we report photometry of 1487 objects detected within 6' of the GRB position. We have removed saturated objects and objects with model magnitudes fainter than 23.0 in the r-band. The fluxes listed in GRB060219_sdss.objects_flux.dat are in nanomaggies while the magnitudes listed in GRB060219_sdss.objects_magnitudes.dat are asinh magnitudes.
  All quantities reported are standard SDSS photometry, meaning that they are very close to AB zeropoints and magnitudes are quoted in asinh magnitudes. Photometric zeropoints are known to about 2% rms. None of the photometry is corrected for dust extinction. The Schlegel, Finkbeiner, and Davis (1998) predictions for this region are A_U=0.172 mag, A_g=0.126 mag, A_r = 0.092 mag, A_i=0.069 mag, and A_z=0.049 mag.
  The file GRB060219_sdss.spectro.dat contains a list of the 2 objects with SDSS spectroscopy within 6 arcminutes of the GRB position. In addition to the redshift and 1-sigma error for each object, this file also lists the object spectroscopic classification.
  SDSS astrometry is generally better than 0.1 arcsecond per coordinate. Users requiring high precision astrometry should take note that the SDSS astrometric system can differ from other systems such as those used in other notices; we have not checked the offsets in this region.
  More detailed information pertaining to our SDSS GRB releases can be found in our initial data release paper (Cool et al. 2006, astro-ph/0601218). See the SDSS DR4 documentation for more details: http://www.sdss.org/dr4.
  These data have been reduced using a slightly different pipeline than that used for SDSS public data releases. We cannot guarantee that the values here will exactly match those in the data release in which these data are included. In particular, we expect the photometric calibrations to differ by of order 0.01 mag.
  This note may be cited, but please also cite the SDSS data release paper, Adelman-McCarthy et al. (2006, ApJS, in press, astro-ph/0507711), when using the data or referring to the technical documentation.
• GCN Circular #4791
  A. Moretti (INAF-OAB), D. Burrows (PSU) report on behalf of the Swift XRT team:
  We have analysed the Swift XRT data from the first orbit observation of GRB 060219 (Moretti et al. GCN 4788). We find an uncatalogued source at the following location:

  RA(J2000) = 16h 07m 21.08s
  Dec(J2000) = 32d 19m 55.9s
  

  We estimate an uncertainty of 6.7 arcseconds radius (90% containment). This position is 1.74 arcminutes from the BAT position given in GCN 4788.

  A. Moretti (INAF-OAB), report on behalf of the Swift XRT team:
  The XRT position of the afterglow of GRB 060219 reported in Moretti et al. (GCN 4791) has a typo; the correct position is

  RA(J2000) = 16h 07m 21.08s
  Dec(J2000) = 32d 18m 55.9s
  

  We estimate an uncertainty of 6.7 arcseconds radius (90% containment). This position is 1.74 arcminutes from the BAT position given in GCN 4788.

Moretti (OAB/INAF), D. Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/NRC), G. Sato (ISAS), J. Tueller (GSFC) on behalf of the Swift-BAT team:
  Using the partial data set from T-60 to T+123 sec from recent telemetry downlinks, we report further analysis of BAT GRB 060219 (trigger #191512) (Moretti, et al., GCN 4788). The BAT ground-calculated position is RA,Dec = 241.815,+32.310 deg {16h 07m 15.5s,+32d 18' 37.7"} (J2000) +- 2.5 arcmin, (radius, sys+stat, 90% containment). The partial coding is 67%. Using this partial data download, there is pre-trigger emission starting before T-60 sec. After the trigger pulse from T+2 to T+10 sec, there is a weak 10-sec wide pulse at T+50 sec, and then nothing out to the T+123 sec limit on the currently available data.
  
• GCN Circular #4797
  A. Moretti (INAF-OAB) reports on behalf of the Swift XRT team:
  Analysing the first seven orbits of data (8.6 ks in Photon Counting mode, in the range from 120 s to 25 ks from the BAT trigger), the following refined position for the X-ray afterglow was determined:

  RA(J2000) =   16h 07' 21.10"
  Dec(J2000) = +32d 18' 56.3"
  

  with an estimated uncertainty of 3.9 arcsec (90% containment). This is 72 arcsec from the BAT position reported by Bathelmy et al. (GCN 4795) and 0.5 arcsec from the XRT position given Moretti et al. (GCN 4793).
  The light-curve shows a single power decay of 0.65 +/- 0.20 from the beginning of the observation (120 s after the trigger) up to 25 ks.
  The spectrum can be fitted with a power-law of photon index Gamma = 2.1 +/- 0.2, assuming a Galactic column of 2.4E+20 cm^-2; there is no evidence for excess NH in these data.
  Assuming the current decay slope of 0.65 continues, and using the spectral fit to the first orbit of data, the XRT count rate is predicted to be 0.006 counts/s at 24 hours, corresponding to an observed flux of 3.0e-13 erg cm^-2 s^-1.

  A. Breeveld (MSSL-UCL), A. Moretti (INAF-OAB) on behalf of the Swift/UVOT team
  The Swift/UVOT began observing the field of GRB 060219 at 22:49:50 UT on 19th February 2006, 105s after the BAT trigger (A.Moretti et al. GCN 4788). No source is detected at the refined XRT position (A. Moretti GCN 4797). Analysing all the data from the first 7000s we obtain the following 5 sigma upper limits:

  Filter        T_range(s)    Exp(s)  5sigUL(mag)
  V            120-320          200        18.6  (the Finding Chart exposure)

  We have imaged the field of GRB060219 (GCN 4788) beginning approximately 12 hours after the trigger notice with the SARA 0.9-m at Kitt Peak, under decent weather conditions. Visual analysis of co-added frame with DSS yields no new sources down to a limiting magnitude of R ~ 19.0 mag when compared to USNO A2.0.

• GCN Circular #4801
  A. Moretti (INAF/OABr) reports on behalf of the Swift/XRT team:
  We looked at the SDSS images of GRB 060219 (Moretti et al., GCN 4788; Barthelmy et al., GCN 4795) provided by Cool et al. (GCN 4789). Inside the revised XRT error circle (Moretti et al., GCN 4797) there is a faint object at the coordinates (J2000):

  alpha = 16:07:21.28;
  delta = +32:18:58.33.
  

  This source is visible in the g, r, i and z frames. After coadding the g, r, and i frames (a saturation spike contaminates the z-band image), the object has extended appearance, being elongated along the N/S direction with FWHM~2.5", and may thus be a galaxy.
  The object has (AB) magnitudes r~21.6, i~20.6, z~20.0, calibrated against nearby SDSS sources.

  Using the data set from T-299 to T+303 sec from the telemetry downlinks, we report further analysis of BAT GRB 060219 (trigger #191512) (Moretti, et al., GCN 4788, Barthelmy, et al., GCN 4795). The BAT ground-calculated position is (RA,Dec) = 241.841, 32.305 deg {16h 7m 21.8s, 32d 18' 18.6"} (J2000) +- 2.1 arcmin, (radius, sys+stat, 90% containment). The partial coding was 67%.
  The mask weighted light curve shows four peaks around T-55, T-35, T+5 and T+55 sec. All 4 peaks are ~10 sec in duration. No other emission is evident in this full data set. T90 (15-350 keV) is (62 +- 2) sec (estimated error including systematics).
  The time-averaged spectrum from T-57.1 to T+8.2 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 2.6 +- 0.4. The fluence in the 15-150 keV band is (4.2 +- 0.8) x 10^-07 erg/cm2. The 1-sec peak photon flux measured from T+4.06 sec in the 15-150 keV band is (0.6 +- 0.2) ph/cm2/sec. All the quoted errors are at the 90% confidence level.
• GCN Circular #4855
  E. Rol (U of Leicester), N. Tanvir (U of Hertsfordshire) and C. Mundell (Liverpool JMU), report on behalf of a larger collaboration:
  We have observed the X-ray position of GRB060219 (Moretti, GCN4788, GCN4797) with the 2m Liverpool Telescope, on two nights in r'- and i'-bands. Within the images, we detect the SDSS-source mentioned by Moretti (GCN4801). In the first epoch r'-band, a very faint source just outside the XRT error circle can be seen as well, with r' ~ 23.4. Image subtraction of the r'-band images between the two epochs shows no variability of the galaxy. The faint source is not visible on the second epoch image, but the second observation is slightly shallower than the first observation, and its estimated source magnitude is around the limiting magnitude of that image. The defringed i'-band images unfortunately suffer from residual fringing and could therefore not be used for image subtraction. No sign of the faint source is seen in these images.
  Our 3-sigma limiting magnitudes, measured in a aperture equal to 1 times the estimated seeing, and calibrated to the SDDS-r' and i' magnitudes, are as follows:

         time             filter          limiting 
  (days post trigger)                    magnitude
        0.220               r'             23.7
        4.15                r'             23.5
        0.276               i'             22.9
        4.17                i'             22.6
  

  We note that the galaxy inside the XRT error circle appears to have slightly different magnitudes than those quoted by Moretti (GCN4801). According to the SDSS derived model magnitudes (Cool, GCN4789), its magnitudes are u' = 25.105, g' = 22.698, r' = 21.941, i' = 21.153 and z' = 20.491. The r' and i' magnitudes are in agreement with the estimates from our photometry.

  D. Sharapov (MAO, and NOT, La Palma), M. Ibrahimov, (MAO), A. Pozanenko (IKI) and V. Rumyantsev (CrAO) on behalf of larger GRB follow up collaboration report:
  We observed the X-ray position of GRB060219 (Moretti et al., CN4788, GCN4797) with 1.5m telescope of Maidanak Astronomical Observatory in R-band on Feb. 20 (UT) 00:41 - 01:09. The SDSS-source (Moretti et al., GCN4801, Rol et al., GCN4855) is clearly detected. We do not detect any other source within or near XRT circle, in particular the faint source mentioned by Rol et al., GCN4855. The R-photometry of the SDSS-source (=galaxy) is following:

  Mid. time,  Exp.,  Galaxy    Limit  Seeing
  (UT)        (s)
  
  Feb.20.039    5x300  21.46 +/- 0.11   22.7   ~1.0"
  

  The photometry is based on SDSS stars (Cool et al., GCN4789) and transformation (Lupton 2005). According to the SDSS derived model magnitudes (Cool, GCN4789) brightness of the galaxy is R=21.72 and our result is marginally consistent with pre-burst observation.
