At 04:07:18 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 190613A (trigger=908288). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 182.559, +67.233 which is
```
   RA(J2000) = 12h 10m 14s
   Dec(J2000) = +67d 13' 58"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single peak structure with a duration of about 30 sec. The peak count rate was ~500 counts/sec (15-350 keV), at ~10 sec after the trigger.
The XRT began observing the field at 04:09:34.8 UT, 136.5 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 182.53286, 67.23489 which is equivalent to:
```
   RA(J2000)  = 12h 10m 07.89s
   Dec(J2000) = +67d 14' 05.6"
```
with an uncertainty of 4.0 arcseconds (radius, 90% containment). This location is 37 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. No spectrum from the promptly downlinked event data is yet available to determine the column density.
The initial flux in the 2.5 s image was 1.18e-09 erg cm^-2 s^-1 (0.2-10 keV).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 144 seconds after the BAT trigger. There is a candidate afterglow in the list of sources generated on-board at
```
  RA(J2000)  =	12:10:07.01 = 182.52919
  DEC(J2000) = +67:14:07.0  =  67.23528
```
with a 90%-confidence error radius of about 1.10 arc sec. This position is 9.9 arc sec. from the center of the XRT error circle. The estimated magnitude is 18.28. No correction has been made for the expected extinction corresponding to E(B-V) of 0.02.
Burst Advocate for this burst is E. Ambrosi (elena.ambrosi AT inaf.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/)

GCN Circular #24799
The Fermi GBM team reports the detection of a likely LONG GRB
At 04:07:18 UT on 13 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190613A (trigger 582091643.234478 / 190613172).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 176.4, Dec = 64.8 (J2000 degrees, equivalent to J2000 11h 45m, 64d 47'), with a statistical uncertainty of 3.0 degrees.

J. Burgess, B. Biltzinger, F. Kunzweiler, F. Berlato, & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 582091643 at 04:07:18 on 13 June 2019 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60).
The best-fit position (1 sigma statistical errors) is:
```
RA(2000.0) = 200.2+/-13.8 deg
Decl.(2000.0) = 66.4+/-3.8 deg
```
We estimate an additional systematic error of 2 deg.

WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on behalf of the KAIT GRB team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to the Swift GRB 190613A (Ambrosi et al., GCN 24798) starting at 734s after the burst. Observations were performed with a sequence in the clear (roughly R), V, and I filters, and the exposure time was 60 s per image. We detected a fading source at the Swfit/UVOT reported afterglow position (Ambrosi et al., GCN 24798) in all the filters. We estimate the clear band magnitude to be ~18.2 at 764s after the burst and faded to ~19.0 at 1290s after the burst. Observation are on going, multi-band follow-ups are encouraged.

J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
Using 3378 s of XRT Photon Counting mode data and 4 UVOT images for GRB 190613A, 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 = 182.52964, +67.23535 which is equivalent to:
```
RA (J2000): 12h 10m 7.11s
Dec (J2000): +67d 14' 07.3"
```
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).

We have analysed 8.1 ks of XRT data for GRB 190613A, from 142 s to 18.3 ks after the BAT trigger. The data comprise 127 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. 24809).
The light curve can be modelled with a series of power-law decays. The initial decay index is alpha=5.1 (+1.1, -0.9). At T+174 s the decay flattens to an alpha of -1.500000 (+0.905300, -0.000007). The light curve breaks again at T+207 s to a decay with alpha=5.0 (+0.7, -0.6), and again at T+372 s s to alpha=1.44 (+0.18, -0.15), before a final break at T+7345 s s after which the decay index is -1.5 (+0.0, -1.4).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.01 (+/-0.12). The best-fitting absorption column is 5.1 (+2.8, -2.6) x 10^20 cm^-2, in excess of the Galactic value of 1.5 x 10^20 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 1.75 (+0.22, -0.15) and a best-fitting absorption column of 2.0 (+4.9, -0.5) x 10^20 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.7 x 10^-11 (3.8 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     2.0 (+4.9, -0.5) x 10^20 cm^-2
Galactic foreground: 1.5 x 10^20 cm^-2
Excess significance: <1.6 sigma
Photon index:	     1.75 (+0.22, -0.15)
```
If the light curve continues to decay with a power-law decay index of -1.5, the count rate at T+24 hours will be 0.41 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 1.5 x 10^-11 (1.6 x 10^-11) erg cm^-2 s^-1.

F. E. Marshall (NASA/GSFC) and E. Ambrosi (INAF-IASFPA) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 190613A 145 s after the BAT trigger (Ambrosi et al., GCN Circ. 24798). A source consistent with the enhanced XRT position (Osborne et al. GCN Circ. 24809) is detected in the initial UVOT exposures.
The preliminary UVOT position is:
```
    RA  (J2000) =  12:10:07.01 = 182.52920 (deg.)
    Dec (J2000) = +67:14:07.0  =  67.23529 (deg.)
```
with an estimated uncertainty of 0.43 arc sec. (radius, 90% confidence).
Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are:

S. Poolakkil (UAH) and C. Meegan (UAH) report on behalf of the Fermi GBM Team:
"At 04:07:18.23 UT on 13 June 2019, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 190613A (trigger 582091643/ 190613172), which was also detected by the Swift/BAT (Ambrosi et al. 2019, GCN 24798). The GBM on-ground location is consistent with the Swift position.
The angle from the Fermi LAT boresight at the GBM trigger time is 9 degrees.
The GBM light curve shows a single peak with a duration (T90) of about 18 s (50-300 keV). The time-averaged spectrum from T0-1.0 s to T0+19.4 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is 0.06 +/- 0.18 and the cutoff energy, parameterized as Epeak, is 108 +/- 5 keV.
The event fluence (10-1000 keV) in this time interval is (3.092 +/- 0.129)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T+11.9 s in the 10-1000 keV band is 2.3 +/- 0.2 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html

Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 190613A (trigger #908288) (Ambrosi et al., GCN Circ. 908288). The BAT ground-calculated position is RA, Dec = 182.552, 67.244 deg which is
```
   RA(J2000)  =  12h 10m 12.5s
   Dec(J2000) = +67d 14' 39.7"
```
with an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 9%.
The mask-weighted light curve shows a weak pulse that starts at ~T0, peaks at ~T+7 s, and ends at ~T+20 s. T90 (15-350 keV) is 17.6 +- 3.1 sec (estimated error including systematics).
The time-averaged spectrum from T+0.6 to T+20.3 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.22 +- 0.26. The fluence in the 15-150 keV band is 1.7 +- 0.3 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+6.88 sec in the 15-150 keV band is 1.5 +- 0.7 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

report:
The 25cm robotic telescope FRAM-ORM at La Palma (Spain) reacted robotically to the alert of GRB190613A (Ambrosi et al, GCNC 24798), starting with a series of 20 s unfiltered images at 04:10:11 UT, i.e. 3 min post trigger.
We clearly detect the source reported by (Ambrosi et al, GCN 24798; Zheng & Filipenko, GCN 24801 and Lipunov et al, GCN 24803), decaying at a rate of alpha ~ 1.51. The brightnes of the object was R = 18.2 +- 0.2 at an image centered at 04:25:15 UT, i.e. 18 min post burst.

V. Cunningham (U of Maryland), J. D. Neill (Caltech), S. B. Cenko (NASA GSFC), and R. Walters (Caltech) report on behalf of the SEDM team:
We observed the optical counterpart to GRB 190613A (Ambrosi et al., GCN 24798) with the Spectral Energy Distribution Machine (SEDM) on the 60 inch telescope at Palomar Observatory. The SEDM is a low resolution (R ~ 100) integral field unit spectrometer with a multi-band (ugri) rainbow camera imager (see Blagorodnova et al. 2018, PASP, 130, 035003, and Rigault et al. 2019, astro-ph/1902.08526).
The SEDM began observing the optical counterpart at 04:18:22 UTC (8.75 minutes after the burst trigger time). We performed an 1800 s exposure over the wavelength range 3800-9200 A. The continuum emission is well-fit by a power law spectrum with index alpha = 0.56 (f_nu ~ nu^-alpha). We detect an absorption line at an observed wavelength of ~ 4597 A. We tentatively identify this line as due to Lyman alpha at z = 2.78 - however due to the lack of corroborating features we consider this redshift tentative currently.
