GCN Circular #6104
T. Sakamoto (NASA/ORAU), S. D. Barthelmy (GSFC), D. N. Burrows (PSU), F. E. Marshall (NASA/GSFC), C. Pagani (PSU), K. L. Page (U Leicester), D. M. Palmer (LANL), P. Schady (MSSL-UCL), M. Stamatikos (NASA/ORAU), R. L. C. Starling (U Leicester) and E. Troja (INAF-IASFPA) report on behalf of the Swift Team:
At 01:10:16 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 070219 (trigger=261132). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 260.198, +69.364 which is
```
   RA(J2000)  =  17h 20m 48s
   Dec(J2000) = +69d 21' 51"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration of about 15 sec. The peak count rate was ~2000 counts/sec (15-350 keV), at ~1 sec after the trigger.
The XRT began taking data at 01:11:38 UT, 82 seconds after the BAT trigger. From ground-based analysis we find a weak source at RA, Dec (J2000) = 260.190, +69.369 which is
```
  RA(J2000)  = 17h 20m 45.5s 
  Dec(J2000) = +69d 22' 10.7" 
```
with an error radius of 5 arcseconds. This is 21 arcseconds from the BAT position.
UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 87 seconds after the BAT trigger. No afterglow candidate has been found in the initial data products at the BAT or XRT position with a white band 3-sigma upper limit of 19.6 mag. The 2.7'x2.7' sub-image covers 25% of the BAT error circle and 100% of the XRT error circle. No correction has been made for the expected extinction corresponding to E(B-V) of 0.035

Richard J. Cool (Arizona), Daniel J. Eisenstein (Arizona), David W. Hogg (NYU), Michael R. Blanton (NYU), David J. Schlegel (LBNL), J. Brinkmann (APO), Donald Q. Lamb (Chicago), Donald P. Schneider (PSU), and Daniel E. Vanden Berk (PSU) report:
The Sloan Digital Sky Survey (SDSS) imaged the field of burst GRB070219 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/GRB070219
We supply FITS images in each of the 5 SDSS bands of a 8'x8' region centered on the GRB position (ra=260.198 (17:20:47.5), dec=69.3640 (69:21:50.4); Swift-BAT TRIGGER 261132), 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 GRB070219_sdss.calstar.dat, we report photometry and astrometry of 256 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 GRB070219_sdss.objects_flux.dat and GRB070219_sdss.objects_magnitudes.dat, we report photometry of 276 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 GRB070219_sdss.objects_flux.dat are in nanomaggies while the magnitudes listed in GRB070219_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=0.178 mag, A_g=0.131 mag, A_r = 0.095 mag, A_i=0.072 mag, and A_z=0.051 mag.
There are currently no objects within 6 arcminutes of the GRB position in the SDSS spectroscopic database.
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, PASP 118, 733). See the SDSS DR4 documentation for more details: http://www.sdss.org/dr5
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, 162, 38), when using the data or referring to the technical documentation.

H. Swan (U Mich), J. Aretakis (U Mich) report on behalf of the ROTSE collaboration: ROTSE-IIIb, located at McDonald Observatory, Texas, responded to GRB 070219 (Swift trigger 261132), producing images beginning 35 minutes after the GCN notice time. An automated response took the first image at 01:44:52.6 UT, 2076.5 s after the burst, under twilight conditions. We took 10 5-sec, 10 20-sec and 6 60-sec eposures. These unfiltered images are calibrated relative to USNO A2.0 (R).
Comparison to the DSS (second epoch) reveals no new sources within the 3-sigma error circle, for both single images and coadding into sets of 10. Individual images have limiting magnitudes ranging from 15.8-17.0; we set the following specific limits.

A. Melandri (Liverpool JMU) on behalf of the Liverpool GRB group reports
The 2-m Liverpool Telescope robotically followed up GRB 070219 (Sakamoto et al., GCN 6104, trigger=261132) beginning 53 min after the GRB trigger time (UT:01:10:16).
The automatic detection mode (3x10sec) did not identify any new bright object inside the XRT error circle (Sakamoto et al., GCN 6104).
Comparison with the USNO B1 for a coadded set of images (for a total exposure time of 300 sec) did not reveal any new object down to a limiting magnitude R~20.2 (between 53-66 minutes after the burst).
Further observations are ongoing.

We observed the field of GRB 070219 (Sakamoto et al., GCN 6104) with the Italian TNG telescope sited in La Palma, Canary Islands. Observations were carried out about 2.02 hours after the burst. No object is present inside the XRT error box (Sakamoto et al., GCN 6104) down to a limiting magnitude of R ~ 25 (3sigma level, calibrated against the USNOB1 catalog).
We acknowledge the support of the TNG staff.

Sakamoto (GSFC/ORAU), G. Sato (GSFC/ISAS), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC) on behalf of the Swift-BAT team:
Using the data set from T-239.9 to T+499.2 sec from the recent telemetry downlink, we report further analysis of BAT GRB 070219 (trigger #261132) (Sakamoto, et al., GCN Circ. 6104). The BAT ground-calculated position is RA, Dec = 260.219, 69.345 deg which is
```
   RA(J2000) = 17h 20m 52.6s 
   Dec(J2000) = 69d 20' 41.4" 
```
with an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment). The partial coding was 92%.
The mask-weighted lightcurve shows a weak FRED-like bump from T-4 to T+20 sec. T90 (15-350 keV) is 17 +- 1 sec (estimated error including systematics).
The time-averaged spectrum from T-1.5 to T+17.7 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.8 +- 0.2. The fluence in the 15-150 keV band is 3.2 +- 0.4 x 10^-07 erg/cm2. The 1-sec peak photon flux measured from T+1.31 sec in the 15-150 keV band is 0.7 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

GCN Circular #6112
R.L.C. Starling (U Leicester), T. Sakamoto (NASA/GSFC), K.L. Page, M.R. Goad and P.A. Evans (U Leicester) report on behalf of the Swift-XRT team:
We have analysed the first four orbits (up to 18.8 ks after the BAT trigger) of Swift XRT data for the faint X-ray afterglow of GRB 070219 (Sakamoto et al., GCN 6104). Using ~6 ks of Photon Counting (PC) mode data we find the following astrometrically corrected XRT refined position (by matching the UVOT images with the USNO-B1 catalogue):
```
RA (J2000)  =  17h 20m 45.99s 
Dec(J2000)  = +69d 22' 10.6"
```
with an error radius of 3.6 arcseconds (90% confidence). This is 95.2, 21.8 and 3.0 arcseconds away from the BAT refined, BAT initial and XRT initial positions respectively.
The lightcurve appears to follow the canonical three-phase decay. It decays with alpha_1~2.2, breaking at T_bk_1~330 s to alpha_2~0.3 and breaking again at T_bk_2~9200 s to a slope of alpha_3~1.5.
The PC mode spectrum, summed over all the data collected thus far, is not tightly constrained, but can be fitted with a single power law of photon index Gamma = 2 and a total absorbing column at z = 0 of nH = 1.3E21 cm-2, in excess of the Galactic value of 4.1E20 cm-2. The 0.3-10 keV observed (unabsorbed) flux is 9E-13 (1.2E-12) erg/cm2/s. There are too few counts for a time-resolved spectral analysis, hence any spectral evolution present cannot be measured.
If the decay continues with a slope of alpha = 1.5, the predicted count rate at 24 hours post-trigger is 5E-4 cts/s. This corresponds to an observed (unabsorbed) flux of 2E-14 (3E-14) erg/cm2/s.
This circular is an official product of the Swift-XRT team.
