GCN Circular #14632
E. Sonbas (NASA/GSFC/Adiyaman Univ.), V. D'Elia (ASDC), P. A. Evans (U Leicester), K. L. Page (U Leicester) and R. L. C. Starling (U Leicester) report on behalf of the Swift Team:
At 07:13:41 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130514A (trigger=555821). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 296.274, -7.956 which is
```
   RA(J2000) = 19h 45m 06s
   Dec(J2000) = -07d 57' 20"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a complex structure with a duration of at least 180 sec. The peak count rate was ~3200 counts/sec (15-350 keV), at ~10 sec after the trigger.
The XRT began observing the field at 07:15:09.9 UT, 88.8 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 296.28055, -7.97808 which is equivalent to:
```
   RA(J2000)  = 19h 45m 07.33s
   Dec(J2000) = -07d 58' 41.1"
```
with an uncertainty of 4.1 arcseconds (radius, 90% containment). This location is 82 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. We cannot determine whether the source is fading at the present time.
A power-law fit to a spectrum formed from promptly downlinked event data gives a column density consistent with the Galactic value of 7.65 x 10^20 cm^-2 (Kalberla et al. 2005).
The initial flux in the 2.5 s image was 5.83e-09 erg cm^-2 s^-1 (0.2-10 keV).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 97 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.23.
Burst Advocate for this burst is E. Sonbas (edasonbas AT yahoo.com). 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 #14633
D. A. Perley (Caltech) reports on behalf of a larger collaboration:
The Palomar 60-inch telescope automatically responded to GRB 130427A (Sonbas et al., GCN 14632) and slewed to the position as soon as the source became observable a few minutes after the GRB alert. A series of r, i, and z-band exposures was taken at very high airmass (~4) starting at 07:25:33 UT, 11.85 minutes after the BAT trigger.
The field is crowded, and contains a small globular cluster (GCl 114) centered at RA=19:45:14.40 Dec=-08:00:26.0 (J2000), 2.5 arcminutes from the GRB.
We do not detect any source at a position coincident with the XRT position in individual images. A stack of the first five r-band images (spanning from 12-27 minutes after the GRB) shows no clear object at this position to a limiting magnitude of R > 19.6 mag (3 sigma), although there is a marginal detection of a source inside the error circle slightly below this level, centered at RA=19:45:07.27, Dec=-07:58:42.3 (J2000, +/-1.5 arcsec). It is also apparent in similar r- and z-band stacks, and so is probably real. The source may also be marginally present in the DSS imaging, although it is not in the USNO B1.0 catalog.
The association of the GRB with the globular cluster (or the optical source) is unclear; this could be an unusual Galactic event or a chance alignment of an ordinary extragalactic GRB (with a faint optical afterglow) with these objects. Further observations are encouraged.
GCN Circular #14634
S. Schmidl, D. A. Kann (both TLS Tautenburg) and J. Greiner (MPE Garching) report on behalf of the GROND team:
We observed the field GRB 130514A (Swift trigger 555821; E. Sonbas et al., GCN 14632) simultaneously in g'r'i'z'JHKs with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG/ESO telescope at La Silla Observatory (Chile).
Observations started at 07:15:31 UT on May 14th, 2 minutes after the SWIFT BAT trigger. They were performed at an average seeing of 1" and at an average airmass of 1.18.
Inside the 2".6 refined XRT error circle, we detect a source not visible in the DSS or SDSS in all 7 bands. The GROND position for this source is:
```
RA (J2000)   =  19:45:07.90
Dec.(J2000)  = -07:58:34.4
```
with an uncertainty of 0".3.
Based on the first 4 min of total exposure we estimate preliminary magnitudes (all in AB system) of
```
g' =  22.17 +- 0.09,
r' =  19.98 +- 0.01,
i' =  19.18 +- 0.02,
J  =  17.87 +- 0.03,
H  =  17.26 +- 0.03 and
K  =  16.81 +- 0.03
```
We propose this source to be the afterglow of GRB 130514A. Additional evidence is the power-law shape of the SED.
The source shows a strong g'-band dropout, we derive a photometric redshift of z = 3.6 +/- 0.2, with an additional small line-of-sight extinction by SMC dust.
Given magnitudes are calibrated against SDSS as well as 2MASS field stars and are not corrected for the expected Galactic foreground extinction corresponding to a reddening of E_(B-V)=0.23 mag in the direction of the burst (Schlegel et al. 1998).

Lien (NASA/GSFC/ORAU), C. B. Markwardt (GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), G. Sato (ISAS), M. Stamatikos (OSU), J. Tueller (GSFC) (i.e. the Swift-BAT team):
Using the data set from T-240 to T+723 sec from recent telemetry downlinks, we report further analysis of BAT GRB 130514A (trigger #555821) (Sonbas, et al., GCN Circ. 14632). The BAT ground-calculated position is RA, Dec = 296.278, -7.974 deg, which is
```
   RA(J2000)  =  19h 45m 06.8s 
   Dec(J2000) = -07d 58' 26.1" 
```
with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 60%.
The mask-weighted light curve shows two peaks, the first starting at ~T-20 sec, peaking at ~T+12 sec, and returning almost to baseline at ~T+80 sec. The second peak starts at ~T+80 sec, peaks at ~T+115 sec, and ends at ~T+380 sec. T90 (15-350 keV) is 204 +- 13 sec (estimated error including systematics).
The time-averaged spectrum from T-7.09 to T+258.01 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.80 +- 0.05. The fluence in the 15-150 keV band is 9.1 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+13.42 sec in the 15-150 keV band is 2.8 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
Using 1035 s of XRT Photon Counting mode data and 2 UVOT images for GRB 130514A, 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 = 296.28288, -7.97592 which is equivalent to:
```
RA (J2000): 19h 45m 7.89s
Dec (J2000): -07d 58' 33.3"
```
with an uncertainty of 1.9 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).

F. E. Marshall (NASA/GSFC) and E. Sonbas (NASA/GSFC/Adiyaman Univ.) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 130514A 97 s after the BAT trigger (Sonbas et al., GCN Circ. 14632). No optical afterglow consistent with the optical position from GROND (Schmidl et al. GCN Circ. 14634) is detected in the initial UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first finding chart (FC) exposure and subsequent exposures are:
```

We observed the field of GRB 130514A (Sonbas et al., GCN 14632) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astron=C3=B3mico Nacion= al on Sierra San Pedro M=C3=A1rtir from 2013/05 14.30 to 2013/05 14.46 UTC (4.7= minutes=20 to 3.90 hours after the BAT trigger), obtaining a total of 2.49 hours exposure in the r' and i' bands and 1.04 hours exposure in the Z, Y, J, and H bands.
For a source within the Swift-XRT error circle, in comparison with USNO-B= 1 and 2MASS, we obtain the following upper limits (3-sigma):
```
  r' > 23.51
  i' > 23.39
  Z > 22.07
  Y > 21.62
  J > 21.43
  H > 21.13
```
These magnitudes are in the AB system and not corrected for Galactic=20 extinction in the direction of the GRB.
Kann et al. (GCN Circular 14634) report a source with r =E2=89=88 20.0 and i =E2=89=88 19.2 in images taken from 2 to 6 minutes after the BAT trigger. Perley (GCN Circular 14633) reports a marginal detection in r and z in images taken from 12 to 27 minutes after the BAT trigger. We began exposing on this field less than 5 minutes after the BAT trigger, but due to the high airmass of almost 5 and poor transparency on the south-eastern horizon, our first useful images are not until about 17 minutes after the trigger. The evolution of our 3-sigma limits is:
```
  i' > 21.72 at 0.49 hours after the trigger
  i' > 22.48 at 1.14 hours
  i' > 23.00 at 1.59 hours
  i' > 23.17 at 2.02 hours
  i' > 23.24 at 2.60 hours
  i' > 23.30 at 3.34 hours
  i' > 23.39 at 3.90 hours
```
If we extrapolate the Kann et al. measurement of i =E2=89=88 19.2 at 4 mi= nutes according to t^-1, we would expect to have detected their source in our observations out to 2 hours. That we did not suggests that light curve fell faster than this. We note that quick-look light curve for Swift-XRT falls by almost three orders of magnitude between about 3 minutes and 20 minutes, which may be consistent with a rapid optical decay.

Skynet observed the Swift/XRT localization of GRB 130515A (Sonbas et al., GCN 14632, Swift trigger #555821) with four 16" telescopes of the PROMPT array at CTIO, Chile and with the 14" telescope at the Appalachian State University Dark Sky Observatory (DSO) in Pisgah National Forest, North Carolina, starting at 2013-05-14, 07:14:32 UT, and continuing until 10:24 UT (t=51s-3.2h post-trigger). It took ~400 exposures, ranging from 5s at early times to 160s at late times, simultaneously in each of the BVRI bands. We performed photometry on each exposure, calibrated to seven USNO-B1/NOMAD stars in the field.
We detect a fading afterglow at t=2-12m in the I band in unstacked images at the position reported by the GROND team (Schmidl, Kann & Greiner, GCN 14640), with I~17.4 at t=2m, fading with an approximate temporal index alpha~-1.2. In stacked images, we obtain weak detections in R band at t=2.27m and 51m, and in V band at t=3.75m; both the R and the V band detections are ~1mag fainter than the I band light curve. In B band, we obtain three weak detections from t=5m to 15m, all ~0.6mag fainter than the I band light curve.
A preliminary plot of our data is at: http://skynet.unc.edu/grb/grb130514a.png
No further Skynet observations are scheduled.

B.P. Gompertz (U. Leicester), A. Maselli (INAF-IASFPA), V. Mangano (INAF-IASFPA), A. Melandri (INAF-OAB), D.N. Burrows (PSU), J.A. Kennea (PSU), M.C. Stroh (PSU), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester) and E. Sonbas report on behalf of the Swift-XRT team:
We have analysed 8.5 ks of XRT data for GRB 130514A (Sonbas et al. GCN Circ. 14632), from 95 s to 37.1 ks after the BAT trigger. The data comprise 405 s in Windowed Timing (WT) mode with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Osborne et al. (GCN. Circ 14637).
The late-time light curve (from T0+5.8 ks) can be modelled with a power-law decay with a decay index of alpha=1.15 (+0.13, -0.12).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 1.82 (+/-0.03). The best-fitting absorption column is 3.14 (+0.13, -0.12) x 10^21 cm^-2, in excess of the Galactic value of 7.6 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 1.99 (+0.20, -0.19) and a best-fitting absorption column of 1.4 (+/-0.5) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.7 x 10^-11 (5.0 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     1.4 (+/-0.5) x 10^21 cm^-2
Galactic foreground: 7.6 x 10^20 cm^-2
Excess significance: 2.1 sigma
Photon index:	     1.99 (+0.20, -0.19)
```
If the light curve continues to decay with a power-law decay index of 1.15, the count rate at T+24 hours will be 9.1 x 10^-3 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 3.4 x 10^-13 (4.5 x 10^-13) erg cm^-2 s^-1.

report:
We performed the Konus-Wind and the Swift/BAT joint spectral analysis of GRB 130514A (Swift/BAT trigger #555821: Sonbas et al., GCN Circ. 14632, Ukwatta et al. GCN Circ. 14636). Since the Konus-Wind observed this GRB in the waiting mode, we only have 3 channel spectral data for the Konus-Wind which cover the energy range from 20 keV to 1.2 MeV. The joint spectral analysis of the Konus-Wind and the Swift/BAT data allows us to derive the broad-band spectral parameters of this burst.
The time interval of the spectral data for each instrument is chosen from T0(BAT)-5.1 to T0(BAT)+153.9 s where T0(BAT) is the trigger time of BAT at 07:13:41 UTC. This interval comprises whole burst as observed by Konus-Wind and contains 87% of the total fluence in the 15-150 keV as observed by BAT (Ukwatta et al. GCN Circ. 14636).
The energy ranges which we used in the joint spectral analysis are 20-1200 keV and 14-150 keV for the Konus-Wind and the Swift/BAT respectively. The spectral data of two instruments are fitted with the spectral model multiplied by the constant factor to take into account the systematic effective area uncertainties in the response matrices of each instrument.
The spectrum is well fitted with a power-law with exponential cutoff model: dN/dE ~ E^{alpha}*exp(-(2+alpha)*E/Epeak). No systematic residual from the best fit model is seen in the spectral data of each instrument. The BAT constant factor is 0.83(-0.08,+0.10) (the KW constant factor is fixed to 1). The best fit spectral parameters are: alpha = -1.44(-0.14,+0.17) and Epeak = 110(-21,+42) keV (chi2/dof = 41.9/57). The best fit spectral parameters for the GRB (Band) model fixing beta = -2.5 are: alpha = -1.44(-0.15,+0.17), and Epeak = 108(-21,+45) keV (chi2/dof = 43.6/57). The energy fluence in the 15-1200 keV band calculated by a power-law with exponential cutoff model for this 159 s interval is 1.40(-0.16,+0.21)x10^-5 erg/cm2.
Assuming a photo-z of 3.6 (Schmidl, Kann, and Greiner GCN Circ. 14634) and a standard cosmology model with H_0 = 71 km/s/Mpc, Omega_M = 0.27, Omega_Lambda = 0.73, the isotropic energy release is E_iso = 4.95(-0.67,+0.85)x10^53 erg in 1 keV to 10 MeV at the GRB rest frame extrapolating the best exponential cutoff function fit.
All the quoted errors are at the 90% confidence level.
