GCN Circular #16433
V. D'Elia (ASDC), S. D. Barthelmy (GSFC), L. Izzo (URoma/ICRA) and M. H. Siegel (PSU) report on behalf of the Swift Team:
At 09:36:04 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140622A (trigger=602278). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 317.152, -14.430 which is
```
   RA(J2000)  =  21h 08m 37s
   Dec(J2000) = -14d 25' 48"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single spike with a duration of about 0.1 sec. The peak count rate was ~2200 counts/sec (15-350 keV), at ~0 sec after the trigger.
The XRT began observing the field at 09:37:37.9 UT, 93.4 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source with an enhanced position: RA, Dec 317.1730, -14.4193 which is equivalent to:
```
   RA(J2000)  = 21h 08m 41.53s
   Dec(J2000) = -14d 25' 09.5"
```
with an uncertainty of 2.6 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.
A power-law fit to a spectrum formed from promptly downlinked event data gives a column density consistent with the Galactic value of 5.47 x 10^20 cm^-2 (Willingale et al. 2013).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 96 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 0.07.
Burst Advocate for this burst is V. D'Elia (delia AT asdc.asi.it). 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 #16434
J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
Using 451 s of XRT Photon Counting mode data and 1 UVOT images for GRB 140622A, 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 = 317.17317, -14.41931 which is equivalent to: RA (J2000): 21h 08m 41.56s Dec (J2000): -14d 25' 09.5" with an uncertainty of 2.6 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 #16435
M. Tanga, C. Delvaux and J. Greiner (all MPE Garching) report on behalf of the GROND team:
We observed the field of GRB 140622A (Swift trigger 602278; D'Elia et al., GCN #16433) 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 ESO La Silla Observatory (Chile).
Observations started at 09:40 UT on June 22, 2014, 0.07 hours after the GRB trigger. They were performed at an average seeing of 1.3 and at an average airmass of 1.23.
We do not detect a source within the Swift-XRT error circle reported by D'Elia et al. (GCN #16433) down to the following 3-sigma AB magnitudes:
```
g' > 24.3 mag,
r' > 24.3 mag,
i' > 24.1 mag,
z' > 24.1 mag,
J > 21.3 mag, 
H > 20.9 mag, and

```
We report the detection of a faint object at the border of the 2.6" Swift-XRT error circle at coordinates
```
   RA(J2000)  =  21:08:41.73
   Dec(J2000) = -14:25:06.5 
```
This object is detected in g', r', i', z' and J and there is no evidence of fading. Its estimated AB magnitudes are
```
g' = 23.4 +/- 0.2 mag,
r' = 23.4 +/- 0.2 mag,
i' = 22.5 +/- 0.1 mag,
z' = 22.2 +/- 0.1 mag, and
J = 20.9 +/- 0.3 mag. 
```
At this time, we cannot assert that this object is the host galaxy of GRB 140622A.
The given limits and magnitudes are derived based on calibrating the images against GROND zeropoints and 2MASS field stars and are not corrected for the Galactic foreground extinction corresponding to a reddening of E_(B-V)= 0.07 mag in the direction of the burst (Schlegel et al. 1998).

We observed the field of short-duration GRB 140622A (D'Elia, et al., GCN 16433) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astron=C3=B3mico Nacional on Sierra San Pedro M=C3=A1rtir from 2014/06 22= .40 to 2014/06 22.47 UTC (1.2 minutes to 1.70 hours after the BAT trigger), obtaining a total of 1.20 hours exposure in the r and i bands and 0.51 hours exposure in the Z and Y bands.
For a source within the Swift-XRT error circle (Osborne, et al., GCN 16434), in comparison with 2MASS, we obtain the following upper limits (3-sigma):
```
  r     > 23.64
  i     > 23.49
 Z     > 19.41
  Y     > 18.73
```
These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB.

We observed the field of short GRB140622A (D'Elia et al., GCN 16433) with the VLT X-shooter spectrograph covering a spectral range 3200A to 18000A, with a total exposure time of 2x600s. Observations started at UT 10:10:32, ~34 minutes after the trigger. The slit was positioned on the object at RA(J2000) = 21:08:41.73, Dec(J2000) = -14:25:06.5 identified by Tanga et al. (GCN 16435), at the border of the 2.6" XRT error circle.
We detect emission lines from this source at a redshift of z~0.959: H-alpha, H-beta, [OII], [OIII]. It is likely that this is the host galaxy of GRB140622A. A very faint trace is detected redwards of ~7000A. This wavelength coincides with a Balmer jump at the host redshift.
We thank the staff at Paranal for their support in obtaining these observations.

Using the data set from T-61 to T+302 sec from the recent telemetry dow= nlink, we report further analysis of BAT GRB 140622A (trigger #602278) (D'Elia, = et al., GCN Circ. 16433). The BAT ground-calculated position is RA, Dec =3D 317.153, -14.412 deg which is

with an uncertainty of 2.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 57%.
The mask-weighted light curve shows a single FRED peak. T90 (15-350 keV)= is 0.13 +- 0.04 sec (estimated error including systematics).
The time-averaged spectrum from T-0.02 to T+0.13 sec is best fit (chisqr = =3D 0.63) by a black body spectrum with kT =3D 11.6 =B1 1.8 keV. A simple power-law m= odel is a relatively poor fit (chisqr 1.13), with a photon index of 3.08 =B1 0.29. = A power-law with an exponential cutoff at 44 =B1 8 keV nominally fits the data almost= as well (chisqr =3D 0.64) as the black body fit, but the power-law index below th= e cutoff energy and the normalization are poorly defined. The fluence in the 15-1= 50 keV band using the black body spectrum is (2.7 =B1 0.5) x 10^-08 erg/cm2. Th= e 1-sec peak photon flux measured from T-0.45 sec in the 15-150 keV band is 0.6 =B1 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence = level.
From the BAT spectrum, this event does not appear to be a short hard bur= st. The quickly fading X-ray lightcurve, however (to be reported in a later circu= lar), does appear consistent with a SHB, and does not appear to be similar to the li= ghtcurves of SGRs or other Galactic sources.

We have analysed 7.3 ks of XRT data for GRB 140622A (D'Elia et al. GCN Circ. 16433), from 103 s to 30.9 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Osborne et al. (GCN Circ. 16434).
The light curve can be modelled with a power-law decay with a decay index of alpha=7.1 (+/-0.9).
If the light curve continues to decay with a power-law decay index of 7.1, the count rate at T+24 hours will be 5.3 x 10^-21 count s^-1

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to Swift GRB 140622A (D'Elia et al., GCN 16433) starting at 09:39:22 UT, 198 s after the burst. Observations were performed with an automatic sequence in the clear (roughly R), V, and I filters, and the exposure time was 20 s per image. We do not detect any new source in our images within the enhanced XRT error circle (Osborne et al., GCN 16434).

We observed the field of GRB 140622A detected by Swift (trigger #602278; D'Elia et al., GCN Circ. 16433) with the iTelescope.Net (http://www.itelescope.net) T11 (0.51 m Planewave) telescope located at the New Mexico Skies Observatory (NM, USA).
60 images of 60 sec exposures were taken in the R filter starting from June 22 09:50:33 (UT) about 14.5 minutes after the trigger and stopped on June 22 11:01:25 (UT). We do not detect the optical afterglow both in the individual images and the stacked image at the enhanced X-ray afterglow position (Osborne et al., GCN Circ. 16434). The estimated five sigma upper limit of the combined image (total exposure of 3600 sec) is ~18.5 using the USNO-B1 catalog.

Klotz A., Turpin D. (IRAP-CNRS-OMP), Boer M., Gendre B., Siellez K., Dereli H., Bardho O. (UNS-CNRS-OCA), Atteia J.L. (IRAP-CNRS-OMP) report:
We imaged the field of GRB 140622 detected by SWIFT (trigger 602278) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile.
The observations started 23.2s after the GRB trigger (12.7s after the notice). The elevation of the field decreased from 61 degrees above horizon and weather conditions were excellents. Images were not accessible during one week due to a disk access problem.
The first image is trailed with a duration of 60.0s (see the description in Klotz et al., 2006, A&A 451, L39). We do not detect any OT with a limiting magnitude of: t0+23.2s to t0+83.2s : R > 17.5
The second image is 30.0s exposure in tracking mode: t0+96.6s to t0+126.6s : R > 18.0
We co-added a series of exposures: t0+96.6s to t0+389.1s : R > 18.4
Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction.

Zhe Chang et al.: Constraining the Lorentz invariance violation from the continuous spectra of short gamma-ray bursts
In quantum gravity, a foamy structure of space-time leads to Lorentz invariance violation (LIV). As the most energetic astrophysical processes in the Universe, gamma-ray bursts (GRBs) provide an effective way to probe quantum gravity effects. We use continuous spectra of 20 short GRBs detected by the Swift satellite to give a conservative lower limit of quantum gravity energy scale $M_\textrm{QG} $. Due to the LIV effect, photons with different energy have different velocities. This will lead to the delayed arrival of high energy photons relative to the low energy ones. Based on the fact that the LIV-induced time delay can't be longer than the duration of a GRB, we present the most conservative estimation of the quantum gravity energy scales from 20 short GRBs. The most strict constraint, $M_\textrm{QG}>5.05\times10^{14}$ GeV, is from GRB 140622A.
