GCN Circular #16606
R. L. C. Starling (U Leicester), C. J. Mountford (U Leicester), K. L. Page (U Leicester) and T. Sakamoto (AGU) report on behalf of the Swift Team:
At 05:53:55.2 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140719A (trigger=605612). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 171.592, -50.135 which is
```
   RA(J2000) = 11h 26m 22s
   Dec(J2000) = -50d 08' 03"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multiple structure with a duration of about 15 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~1 sec after the trigger.
The XRT began observing the field at 05:55:14.4 UT, 79.2 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source with an enhanced position: RA, Dec 171.6008, -50.1350 which is equivalent to:
```
   RA(J2000)  = 11h 26m 24.20s
   Dec(J2000) = -50d 08' 06.1"
```
with an uncertainty of 2.4 arcseconds (radius, 90% containment). This location is 20 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 in excess of the Galactic value (1.63 x 10^21 cm^-2, Willingale et al. 2013), with an excess column of 1.1 (+1.09/-0.78) x 10^22 cm^-2 (90% confidence).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 83 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. Data from the 2.7'x2.7' sub-image are not available at this time. 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 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.14.
Burst Advocate for this burst is R. L. C. Starling (rlcs1 AT star.le.ac.uk). 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 #16607
P.A. Evans, M.R. Goad, J.P. Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team.
Using 962 s of XRT Photon Counting mode data and 2 UVOT images for GRB 140719A, 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 = 171.60118, -50.13491 which is equivalent to:
```
RA (J2000): 11h 26m 24.28s
Dec (J2000): -50d 08' 05.7"
```
with an uncertainty of 2.0 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).
This circular was automatically generated, and is an official product of the Swift-XRT team.
GCN Circular #16608
V. Mangano (PSU), C. Pagani (U. Leicester), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), B. Sbarufatti (INAF-OAB/PSU), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC), M.C. Stroh (PSU), D.N. Burrows (PSU) and R.L.C. Starling report on behalf of the Swift-XRT team:
We have analysed 8.8 ks of XRT data for GRB 140719A (Starling et al. GCN Circ. 16606), from 64 s to 24.1 ks after the BAT trigger. The data comprise 8 s in Windowed Timing (WT) mode (taken while Swift was slewing), with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Evans et al. (GCN Circ. 16607).
The light curve can be modelled with a series of power-law decays. The initial decay index is alpha=3.1 (+1.5, -0.8). At T+276 s the decay flattens to an alpha of -0.6 (+0.5, -0.8) before breaking again at T+2558 s to a final decay with index alpha=0.76 (+/-0.15).
A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.09 (+0.23, -0.21). The best-fitting absorption column is 2.8 (+0.9, -0.8) x 10^21 cm^-2, in excess of the Galactic value of 1.6 x 10^21 cm^-2 (Willingale et al. 2013). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.5 x 10^-11 (5.3 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     2.8 (+0.9, -0.8) x 10^21 cm^-2
Galactic foreground: 1.6 x 10^21 cm^-2
Excess significance: 2.4 sigma
Photon index:	     2.09 (+0.23, -0.21)
```
If the light curve continues to decay with a power-law decay index of 0.76, the count rate at T+24 hours will be 0.013 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 4.4 x 10^-13 (6.8 x 10^-13) erg cm^-2 s^-1.

GCN Circular #16611
J. Bolmer, F. Knust, K. Valera and J. Greiner (all MPE Garching) report on behalf of the GROND team:
We observed the field of GRB 140719A (Swift trigger 605612; Cummings et al., GCN 16606) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2m MPG telescope at ESO La Silla Observatory (Chile).
Observations started at 22:59 UT on July 19, 2014, 16.8 hrs after the GRB trigger. They were performed at an average seeing of 1.1" and at an average airmass of 1.5.
We find a faint source inside the XRT error circle given in Evans et al. (GCN 16607) at coordinates RA, Dec =3D 171.60123, -50.13466, which is equal to:
```
RA  (J2000): 11:26:24.3
Dec (J2000): -50:08:04.8
```
with an uncertainty of 0.5=E2=80=9C in each coordinate.
Based on a total exposures of 3000 seconds in g'r'i'z' and 1200 seconds in JHK, at a mid-time of 18.4 hrs after the burst, we measure the following preliminary magnitudes (all in AB):
```
g' > 25.3,
r' = 23.7 +/- 0.2,
i' = 22.9 +/- 0.2,
z' > 23.8,
J  > 21.4,
H  > 20.9 and
K  > 19.5.
```
At present we cannot confirm whether the source is fading.
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) = 0.12 mag in the direction of the burst (Schlegel et al. 1998).
GCN Circular #16612
C. Guidorzi, S. Dichiara (U. Ferrara), C.G. Mundell (LJMU) on behalf of a large collaboration report:
The 2-m Faulkes Telescope South began observing Swift GRB 140719A (Starling et al. GCN Circ 16606) on July 19 at 09:27:35 UT, i.e. ~3.6 hours after the BAT trigger, with the r' and i' filters.
Within the enhanced XRT error circle (Evans et al. GCN Circ. 16607) and, in particular, at the position of the GROND candidate (GCN Circ. 16611) we found nothing down to the following limit:
```
Mid time from  Total Exp   Filter    Magnitude
trigger (hr)   (s)
-------------------------------------------------
3.64           120x4       r'        > 21.0
3.80           120x4       i'        > 20.2
-------------------------------------------------
```
Magnitudes are calibrated against nearby USNO-B1 stars.

Tueller (GSFC), (i.e. the Swift-BAT team):
Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 140719A (trigger #605612) (Starling, et al., GCN Circ. 16606). The BAT ground-calculated position is RA, Dec = 171.571, -50.115 deg which is
```
  RA(J2000)  =  11h 26m 17.1s 
  Dec(J2000) = -50d 06' 55.1" 
```
with an uncertainty of 2.4 arcmin, (radius, sys+stat, 90% containment). The partial coding was 75%.
The mask-weighted light curve shows a single peak starting at ~T-5 s sec, peaking at ~T+0 sec, and ending at T+20 sec. T90 (15-350 keV) is 48 +- 23 sec (estimated error including systematics).
The time-averaged spectrum from T-31.5 to T+16.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.9 +- 0.3. The fluence in the 15-150 keV band is 4.3 +- 0.8 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T+8.01 sec in the 15-150 keV band is 0.2 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

GCN Circular #16618
F. E. Marshall (NASA/GSFC) and R. L. C. Starling (U. Leicester) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 140719A 83 s after the BAT trigger (Starling et al., GCN Circ. 16606). No optical afterglow consistent with the optical position (Bolmer et al. GCN Circ. 16611) or the enhanced XRT position (Evans et al. GCN Circ. 16607) is detected in the initial UVOT exposures. Nearby bright sources in this crowded field make estimating the background more difficult than usual. 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:
```

```
The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.14 in the direction of the burst (Schlegel et al. 1998).
