GCN Circular #16353
M. C. Stroh (PSU), A. P. Beardmore (U Leicester), J. R. Cummings (NASA/UMBC), P. A. Evans (U Leicester), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), F. E. Marshall (NASA/GSFC), P. Romano (INAF-IASFPA) and R. L. C. Starling (U Leicester) report on behalf of the Swift Team:
At 10:58:13 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140606A (trigger=600951). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 201.808, +37.579 which is
```
   RA(J2000) = 13h 27m 14s
   Dec(J2000) = +37d 34' 44"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double peak structure with a duration of about 1 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger.
XRT is currently not collecting science data. There will be no XRT data on this burst until the anomaly is resolved. Details are given in GCN Circ. 16349.
UVOT took a finding chart exposure of 150 seconds with the White filter starting 67 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 25% of the BAT 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 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 0.01.
Burst Advocate for this burst is M. C. Stroh (stroh AT astroh.org). 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.)

Sakamoto (AGU), M. Stamatikos (OSU), M. C. Stroh (PSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team):
Using the data set from T-240 to T+962 sec from recent telemetry downlinks, we report further analysis of BAT GRB 140606A (trigger #600951) (Stroh, et al., GCN Circ. 16353). The BAT ground-calculated position is RA, Dec = 201.799, 37.599 deg, which is
```
   RA(J2000)  =  13h 27m 11.7s 
   Dec(J2000) = +37d 35' 56.5" 
```
with an uncertainty of 2.4 arcmin, (radius, sys+stat, 90% containment). The partial coding was 86%.
The mask-weighted light curve shows a single spike starting at ~T+0.0, peaking at ~T+0.1, and ending at ~T+0.3 sec. T90 (15-350 keV) is 0.34 +- 0.09 sec (estimated error including systematics).
The time-averaged spectrum from T-0.04 to T+0.35 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 0.53 +- 0.36. The fluence in the 15-150 keV band is 5.1 +- 1.0 x 10^-8 erg/cm2. The 1-sec peak photon flux measured from T-0.34 sec in the 15-150 keV band is 0.5 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

GCN Circular #16357
M. C. Stroh, J. A. Kennea (PSU), N. Gehrels (GSFC) and D. Malesani (DARK/NBI) report on behalf of the Swift-XRT team:
The Swift-XRT began observing the field of GRB 140606A 4.6 ks after the event (Stroh et al., GCN Circ. 16353). In 2.4ks of Photon Counting (PC) mode data, no source was found in the revised BAT error circle (Cummings et al., GCN Circ. 16354). The three sigma upper limit (0.5-10 keV) is 7.4e-3 counts s^-1.
The delayed XRT response was due to the XRT anomaly (Burrows and Kennea, GCN Circ. 16356).
This circular is an official product of the Swift team.
GCN Circular #16358
F. E. Marshall (NASA/GSFC) and M. C. Stroh (PSU) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 140606A 68 s after the BAT trigger (Stroh et al., GCN Circ. 16353). No optical afterglow consistent with the BAT position (Cummings et al. GCN Circ. 16354) 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:
```

The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.01 in the direction of the burst (Schlegel et al. 1998).

D. Xu (DARK/NBI), H.-B. Niu, T.-Z. Yang, A. Esamdin, L. Ma (XAO) report:
We observed the BAT field of GRB 140606A (Stroh et al., GCN 16353) using the 1m telescope located at Nanshan, Xinjiang, China. Observations started at 15:49:48 UT on 2014/06/06 (4.86 hr after the burst) and a series of 300s/500s R-band frames were obtained.
The optical afterglow of the burst is not detected within the BAT error circle down to a limiting magnitude of R=20.8 mag, calibrated with the nearby SDSS field.

A coadd of 105 images (60s each, i=E2=80=99-band filter) taken starting at 20:46 UT and ending at 01:33 UT (i.e. 10 hr post burst) reveals no optical afterglow down to 18.8 mag."

A. Volnova (IKI), R. Inasaridze (AAO), O. Kvaratskhelia (AAO), V. Ayvazian (AAO), Yu. Krugly (IA KhNU), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration:
We observed a field of the Swift GRB 140606A (Stroh et al., GCN 16353)=20 with AS-32 (0.7m) telescope of Abastumani Observatory starting on June, 06 (UT) 18:16:50. We obtained several unfiltered frames with exposure of=20 each frame of 120 s. Within the BAT ground-calculated position (Cummings=20 et al., GCN 16354) we do not detect evident variable source.
The details of the photometry are the following:

We observed the field of the short GRB 140606A (Stroh et al., GCNC 16353) 11.3 h after with the 6-meter BTA (+Scorpio-I) at SAO-RAS (Zelenchuk, Russia). Comparison images (R-band) were obtained with the 1.5m telescope at Observatorio de Sierra Nevada (south Spain) 60 h post burst. Within the refined BAT gamma-ray burst error circle (Cummings et al., GCNC 16354), we identify no variable object down to R = 22, in agreement with the limit reported by Volnova et al. (GCNC 16371).
