GCN Circular #15825
S. T. Holland (STScI), V. D'Elia (ASDC), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), H. A. Krimm (CRESST/GSFC/USRA), V. Mangano (PSU), F. E. Marshall (NASA/GSFC), C. J. Mountford (U Leicester), P. T. O'Brien (U Leicester), C. Pagani (U Leicester), K. L. Page (U Leicester), J. L. Racusin (NASA/GSFC), M. H. Siegel (PSU) and B.-B. Zhang (UAH) report on behalf of the Swift Team:
At 19:21:37 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140213A (trigger=586569). Swift did not slew to the burst immediately. The BAT on-board calculated location is RA, Dec 105.218, -73.136 which is
```
   RA(J2000) = 07h 00m 52s
   Dec(J2000) = -73d 08' 10"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed two strong peaks starting at T-5, with a total duration of about 10 sec, followed by a third weaker pulse at T+15. The peak count rate was ~18,000 counts/sec (15-350 keV), at ~1 sec after the trigger.
Due to an observing constraint, Swift will not slew until T0+54.8 minutes. There will be no XRT or UVOT data until this time.
Burst Advocate for this burst is S. T. Holland (sholland AT stsci.edu). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)

GCN Circular #15826
M. H. Siegel (PSU) and S. T. Holland (STScI) report on behalf of the Swift/UVOT team:
UVOT took a finding chart exposure of 150 seconds with the White filter starting 3428 seconds after the BAT trigger on GRB 140213A (Holland et al., GCN Circ. 15825). There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at

 RA(J2000)  =	07:00:37.09 = 105.15455
 DEC(J2000) = -73:08:13.5  = -73.13707
```
with a 90%-confidence error radius of about 0.62 arc sec. This position is 6.2 arc sec. from the center of the XRT error circle. The estimated magnitude is 17.74 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.15.

P.A. Evans (U. Leicester), J.P. Osborne (U. Leicester), D.N. Burrows (PSU), J.A. Kennea (PSU), M. Perri (ASDC) and G. Tagliaferri (INAF-OAB) report on behalf of the Swift-XRT team:
The XRT began observing the field of GRB 140213A at 20:18:43.0 UT, 3425.3 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source located at RA, Dec 105.15145, -73.13570 which is equivalent to:
```
   RA(J2000)  = 07h 00m 36.35s
   Dec(J2000) = -73d 08' 08.5"
```
with an uncertainty of 3.6 arcseconds (radius, 90% containment). This location is 69 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper.
A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (1.13 x 10^21 cm^-2, Kalberla et al. 2005), with an excess column of 2.4 (+1.68/-1.51) x 10^21 cm^-2 (90% confidence).

Skynet observed the Swift-BAT localization of GRB 140213A (Holland et al., GCN 15825, Swift trigger 586569) with the 14-inch R-COP telescope at Perth Observatory, Australia. Observations began at 59s and continued until 92m post-trigger, with rotating exposures in the BVRI bands increasing from 10s to 80s. We detect a fading optical source in all bands at the position of the source detected by the Swift UVOT (Siegel & Holland, GCN 15826). The source faded from R=14.3 at t=113s to R=17.8 at t=73m.
A preliminary light curve is at: http://www.skynet.unc.edu/grb/grb140213a.png
Photometry is calibrated to five APASS-DR7 stars in the field, and has not been corrected for the Galactic foreground extinction corresponding to E(B-V)=0.07 (Schlegel et al. 1998).
Skynet observations are ongoing.
GCN Circular #15829
J. Elliott, K. Varela (both MPE Garching), D. A. Kann (TLS Tautenburg), and J. Greiner (MPE Garching) report on behalf of the GROND team:
We observed the field of GRB 140213A (Swift trigger 586569; Holland et al., GCN #15825) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at La Silla Observatory (Chile).
Observations started at 00:25 UT on 14 February 2014, 5 hours after the GRB trigger, and are continuing. They were performed at an average seeing of 1.9" and at an average airmass of 1.4.
We find a single point source within the 0.4" Swift-UVOT error circle reported by Siegel & Holland (GCN #15826) and confirmed by Trotter et al. (GCN #15828).
Based on the first 4.4 min of total exposures in g'r'i'z' and 4 min in JHK, we estimate preliminary magnitudes (all in AB) of
```
g' = 19.7 +/- 0.1 mag,
r' = 19.4 +/- 0.1 mag,
i' = 19.2 +/- 0.1 mag,
z' = 19.1 +/- 0.1 mag,
J  = 18.7 +/- 0.1 mag,
H  = 18.5 +/- 0.1 mag, and
K  = 18.4 +/- 0.1 mag.
```
The spectral energy distribution is best-fit by a straight power-law with spectral slope b = 0.8 +/- 0.1.
Given magnitudes are calibrated against GROND zeropoints as well as 2MASS field stars and are not corrected for the expected Galactic foreground extinction corresponding to a reddening of E_(B-V)=0.07 mag in the direction of the burst (Schlegel et al. 1998).
GCN Circular #15830
A.P. Beardmore, P.A. Evans, M.R. Goad and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team.
Using 3106 s of XRT Photon Counting mode data and 7 UVOT images for GRB 140213A, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 105.15491, -73.13725 which is equivalent to:
```
RA (J2000): 07h 00m 37.18s
Dec (J2000): -73d 08' 14.1"
```
with an uncertainty of 1.5 arcsec (radius, 90% confidence).
This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).

S. Schulze (PUC and MCSS), K. Wiersema (U. Leicester), D. Xu, and J. P. U. Fynbo (DARK/NBI) report on behalf of a larger collaboration:
We observed the optical counterpart of GRB 140213A (Holland et al., GCN 15825; Siegel et al., GCN 15826) with the ESO VLT equipped with the X-shooter spectrograph starting 5.8 hr after the GRB. The spectrum covers the wavelength range from 3,200 to 18,000 AA. The afterglow is well detected throughout. We detect several absorption features, which we interpret as due to Fe II, Mg I, Mg II, Al II, Al III and others, at a common redshift of z = 1.2076 (wavelength solution based on archival calibration lamps).
We acknowledge excellent support from the observing staff in Paranal, in particular Yazan Momany.
GCN Circular #15832
C. Pagani (U. Leicester), K. L. Page (U. Leicester) and S. T. Holland (STScI) report on behalf of the Swift-XRT team:
We have analysed 5.0 ks of XRT data for GRB 140213A (Holland et al. GCN Circ. 15825), from 3.4 ks to 22.3 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Beardmore et al. (GCN Circ. 15830).
The light curve can be modelled with a power-law decay with a decay index of alpha=1.04 (+/-0.06).
A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 1.91 (+/-0.08). The best-fitting absorption column is 1.4 (+1.0, -0.9) x 10^21 cm^-2, at a redshift of 1.2076, in addition to the Galactic value of 1.1 x 10^21 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.9 x 10^-11 (5.2 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Galactic foreground: 1.1 x 10^21 cm^-2
Intrinsic column:    1.4 (+1.0, -0.9) x 10^21 cm^-2 at z=1.2076
Photon index:	     1.91 (+/-0.08)
```
If the light curve continues to decay with a power-law decay index of 1.04, the count rate at T+24 hours will be 0.085 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 3.4 x 10^-12 (4.4 x 10^-12) erg cm^-2 s^-1.
The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00586569.

Bin-Bin Zhang (UAH) reports on behalf of the Fermi GBM Team:
"At 19:21:32.35 UT on February 13 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140213A (trigger 414012095/140213807), which was also detected by Swift (Holland et al., GCN 15825). The GBM on-ground location is consistent with the Swift/XRT position (Evans et al., GCN 15827).
The trigger resulted in an Autonomous Repoint Request (ARR) that was accepted and the spacecraft slewed to the GBM in-flight location. The pre-ARR angle from LAT boresight was 48.5 deg from the Swift/XRT position.
The GBM light curve consists of a multiple-peak structure with a duration of about 18.6 s (50-300 keV). The time-averaged spectrum from T0+0 s to T0+19 s is well fit with a Band function parameterized as Epeak = 80 +/- 2 keV, alpha = -1.01 +/- 0.03 and beta=-2.41 +/-0.04. The event fluence (10-1000 keV) in this time interval is (2.04 +/- 0.03)E-05 erg/cm^2. The 1.0-sec peak photon flux measured starting from T0+6 s in the 10-1000 keV band is 37 +/- 0.5 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

M. H. Siegel (PSU) and S. T. Holland (STScI) report on behalf of the Swift/UVOT team:
The Swift/UVOT has continued to observe GRB 140213A (Holland et al., GCN 15825). We find that the optical afterglow is slowly fading but still detected in all UVOT filters as of 68 ks after the BAT trigger.
The preliminary UVOT position is:

   RA  (J2000) =  07:00:37.13 = 105.15472 (deg.)
   Dec (J2000) = -73:08:13.5  = -73.13707 (deg.)

with an estimated uncertainty of 0.51 arc sec. (radius, 90% confidence).
Preliminary detections using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) are:

Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 140213A (trigger #586569) (Holland, et al., GCN Circ. 15825). The BAT ground-calculated position is RA, Dec = 105.166, -73.136 deg which is
```
    RA(J2000)  =  07h 00m 39.8s
    Dec(J2000) = -73d 08' 10.8"
```
with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 50%.
The mask-weighted light curve begins at T-120 sec, when the source position came into the BAT field-of-view during a pre-planned slew. The emission begins faintly at ~T-25 sec, and rises sharply beginning at ~T-5.5 sec, peaks at T-4 sec and a stronger peak at ~T+1 sec, returning almost to baseline around T+10 sec. Then there is a second, much weaker and softer pulse at around T+15 sec, followed by an even weaker pulse at ~T+70 sec, with extended emission out to ~T+160 sec. The burst position left the FoV after another pre-planned slew at T+780 sec. T90 (15-350 keV) is 60.0 +- 2.6 sec (estimated error including systematics).
The time-averaged spectrum from -5.7 to +82.0 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.80 +- 0.04. The fluence in the 15-150 keV band is 1.2 +- 0.0 x 10^-5 erg/cm2. The 1-sec peak photon flux measured from T+0.56 sec in the 15-150 keV band is 23.5 +- 0.8 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

S. Golenetskii, R.Aptekar, D. Frederiks, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report:
The long-duration GRB 140213A (Swift-BAT trigger 586569: Holland et al., GCN 15825; Stamatikos et al., GCN 15836; Fermi GBM Detection: Zhang, GCN 15833) triggered Konus-Wind at T0=3D69693.011 s UT (19:21:33.011).
The burst light curve shows a bright, double-peaked pulse with a total duration of ~16 s followed by a weaker emission during the next ~50 s. The emission is seen up to ~12 MeV.
The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB140213_T69693/
As observed by Konus-Wind, the burst had a fluence of (1.57 =B1 0.09)x10^-5 erg/cm2, and a 64-ms peak flux, measured from T0+1.344 s, of (4.10 =B1 0.40)x10^-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range).
The time-averaged spectrum (measured from T0 to T0+16.640 s) is best fit in the 20 keV - 18 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha =3D -1.39 =B1 0.06, the high energy photon index beta =3D -3.55 =B1 0.88, the peak energy Ep =3D 100 =B1 4 keV, chi2 =3D 142/97 dof.
The spectrum near the maximum count rate (measured from T0 to T0+8.448 s) is best fit in the 20 keV - 18 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha =3D -0.46 =B1 0.12, the high energy photon index beta =3D -3.28 =B1 0.40, the peak energy Ep =3D 108 =B1 4 keV, chi2 =3D 137/97 dof.
Assuming the redshift z=3D1.2076 (Schulze et al., GCN 15831), and a standard cosmology model with H_0 =3D 70 km/s/Mpc, Omega_M =3D 0.27, and Omega_Lambda =3D 0.73, we estimate the following rest-frame parameters: the isotropic energy release E_iso is (6.2 =B1 0.4)x10^52 erg, the peak luminosity L_iso is (3.6 =B1 0.4)x10^52 erg/s, and the rest-frame peak energy Ep,i =3D (221 =B1 8) keV
All errors are given at 1 sigma level. All the quoted values are preliminary.

Skynet continued observing the Swift-BAT localization of GRB 140213A (Holland et al., GCN 15825, Swift trigger 586569) with the 14-inch R-COP telescope at Perth Observatory, Australia, and with 4 16-inch telescopes of the PROMPT array at CTIO, Chile. Previous observations with R-COP began at 59s and continued until 92m post-trigger (Trotter et al., GCN 15828). Observations resumed with PROMPT-CTIO at t=5.5h, and continued at R-COP and PROMPT-CTIO until t=32h, with a total of ~600x160s new exposures in the BVRI bands.
We continue to detect an uncatalogued optical source in all bands at the position of the source detected by the Swift UVOT (Siegel & Holland, GCN 15826). The source faded from R=14.3 at t=113s to R=17.8 at t=73m, bottomed out at R=19.0 at t~6h, and then rebrightened to R=18.6 by t=23h. Flattening or rebrightening of the light curve is observed in all four bands.
An updated light curve is at: http://www.skynet.unc.edu/grb/grb140213a_2.png
Magnitudes are in the Vega system, calibrated to ten APASS-DR7 stars in the field, and have not been corrected for the Galactic foreground extinction corresponding to E(B-V)=0.07 (Schlegel et al. 1998).
Skynet observations are ongoing.

R-COP and PROMPT-CTIO took a total of 284x160s exposures in BVRI between t~5-5.3d. In stacked images, we continue to detect an uncatalogued optical source in R and I bands at the position of the source detected by the Swift UVOT (Siegel & Holland, GCN 15826). After the rebrightening at t~1d, the source clearly resumed fading.
