Turler, V.Beckmann, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: A GRB lasting about 180 s has been detected by IBAS in IBIS/ISGRI data at 11:18:11 UT of June 3. The coordinates (J2000) are: RA: 279.409 [degrees] DEC: +62.735 [degrees] with an uncertainty of 2 arcmin (90% c.l.). A preliminary analysis gives a peak flux in the 20-200 keV range of about 0.5 ph/cmq/s (1-s integration time) and a fluence over the same energy range of about 10e-6 erg/cmq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html This message can be cited.

Bloom (UC Berkeley), and J. X. Prochaska (UCO/Lick) report on behalf of a larger collaboration: Following the KAIT detection (Chornock et al., GCN 7789) of the afterglow candidate of GRB 080603 (Paizis et al., GCN 7790; Gomboc et al., GCN 7788) we began a spectroscopic sequence at Gemini-North using GMOS. We acquired 2x1200s longslit exposures starting at UT 13:24. We detect very strong resonance lines of MgII and FeII and the fine-structure transitions of FeII which establish the redshift of the GRB to be z=1.6880. In addition, we identify intervening MgII absorption systems at z=1.5635 (90% c.l.) and z=1.271 (100% c.l.) In addition, in a single acquisition exposure starting at UT 13:05:05 (107 minutes after the trigger) the object has a magnitude (relative to USNO B1.0) of R~19.7, suggesting it has not faded significantly since the observations of Gomboc et al. (GCN 7788). We thank Richard McDermid and the Gemini staff and for support.

Milne (U Arizona) and A. Updike (Clemson U) report on behalf of the Super-LOTIS team: The 0.6m Super-LOTIS telescope began R-band observations of the error region of GRB080603 at 11:19:04 UT. The OT detected by Gomboc et al. (GCN 7788) and Chornock et al. (GCN 7789) is not apparent in the initial images, but is clearly visible in subsequent images. Using a stack of 10 x 60sec images obtained between 11:22:44 -> 11:33:46, we estimate the magnitude of the source to be R=19.3 +/- 0.3. We used the USNO-B star at RA=18:37:55, Dec=+62:44:32 to derive the R2 magnitude. Analysis continues to better characterize the rise of the emission from the OT. This message can be cited.

Mangano (INAF), report on behalf of the Swift UVOT team The Swift UltraViolet/Optical Telescope (UVOT) began observations of INTEGRAL burst GRB080603A (INTEGRAL trigger number 5283, Paizis et al., GCN Circ. 7790), on June 3, 2008, at 14:11:20 UT, 173 minutes after the initial trigger in the UVOT v filter. We detect a fading source at position : RA=18:37:38.21 Dec=+62:44:38.40 (279.40921 +62.74400 ddeg (J2000)). The initial magnitude observed for GRB080603A is given below for the first observation in the UVOT v filters: Filter Tstart(s) Tstop(s) Exp(s) Magnitude v 10389 10499 109. 19.16 +/- 0.35 The magnitude decrease observed was 1.2 magnitudes per hour. The values quoted above are on the UVOT Photometric System (Poole et al, 2008, MNRAS 383,627). They are not corrected for the expected galactic reddening of E(B-V) = 0.044 in the direction of the burst (Schlegel et al. 1998).

Mangano, V. La Parola (INAF-IASF Pa) report on behalf of the Swift-XRT team The Swift XRT began observations of the INTEGRAL burst GRB 080603A (Paizis et al., GCN Circ 7790) on June 3, 14:11 UT, 173 minutes after the trigger. The data consist of 3.9 ks observed in Photon Counting mode. We detect an X-ray counterpart at position (astrometrically corrected using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 279.40858, 62.74446 which is equivalent to: RA (J2000): 18 37 38.06 Dec (J2000): +62 44 40.1 with an uncertainty of 1.9 arcsec (radius, 90% confidence). The light curve is dominated by a flare-like structure which covers all the observed time interval, making it impossible to estimate the behaviour of the underlying continuum and to predict the evolution of the source. The spectrum can be fitted with a powerlaw with an intrinsic absorbing column of (8+/-5)e21 cm-2 at z=1.688 (Perley et al., GCN Circ 7791) and photon index 2.4 0.3. The observed (unabsorbed) 0.3-10 keV flux is 3.23 (3.57)e-12 erg cm-2 s-1. This circular is an official product of the Swift-XRT team.

Ertel (TLS Tautenburg) report: We observed the field of the INTEGRAL GRB 080603A (Paizis et al., GCN 7790) with the TLS 1.34m Schmidt telescope in mediocre observing conditions (low airmass but high humidity and moderate transparency). We obtained a total of 6 x 600 sec images at mid-time June 5.023368. The afterglow (Gomboc et al., GCN 7788; Chornock et al., GCN 7789) is faintly visible in each image. We stacked all six images. Assuming the USNOB1.0 star with ID 1527-0313986 at RA = 18:37:55.186, Dec. +62:45:32.28 to have R1 = 16.74 mag, we measure for the afterglow: dt Rc dRc 1.55241 21.39 0.03 (statistical only) We note the presence of a fainter source several arcseconds east of the OT which may slightly influence the photometry. In comparison to the magnitude measured by Perley et al. (GCN 7791), this implies a slow decay of alpha ~ 0.5. Further observations are warranted. This message may be cited.

Perley (UC Berkeley) report: We observed the optical afterglow of GRB080603A (Paizis et al., GCN 7790; Gomboc et al., GCN 7788; Chornock et al; GCN 7789) with the 1.3m Peters Automated Infrared Imaging Telescope (PAIRITEL) starting 18.89 hours post trigger on June 04, 2008 UT. We detected the afterglow in a 2927 sec mosaic of simultaneous 7.8 sec exposures in the J, H, and Ks filters. Preliminary photometry for the afterglow in exposures beginning on Jun 04.26 UT yields J = 18.9 +- 0.15, H = 17.9+- 0.15, and Ks = 16.8 +- 0.15, calibrated to the 2MASS system.

Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed a field of INTEGRAL GRB 080603A (Paizis et al., GCN 7790) in R-band on June 06 between (UT) 22:32 - 23:55 with Zeiss-1000 (Simeiz) telescope of CrAO observatory. Extended object is found ~1" south from the position of optical afterglow (Gomboc et al., GCN 7788; Chornock et al., GCN 7789), and the position of the extended object is consistent with coordinates reported by Kuin et al. (GCN 7804). Therefore, we suggest it as a host galaxy of 080603A. Based on USNOB1.0 star with ID 1527-0313986 at RA = 18:37:55.186, Dec. +62:45:32.28 (R1 = 16.74) we estimated brightness of the extended object: UT, Exposure, R_mag, UL (mid time) 3.496 41x120 21.90 +/- 0.17 22.85 If the extended source is the host galaxy then contamination by the host can explain slow decay of light curve noted by Kann et al.

La Parola (INAF-IASF Pa) report on behalf of the Swift-XRT team. Swift-XRT continued observing the afterglow of the INTEGRAL-detected GRB 080603A. After the first detection of the X-ray afterglow, showing flare like activity previously reported (Sbarufatti et al., GCN Circ. 7810) Swift detected the source also at T+234 ks, with count-rate (8+/-2)E-3 counts/s (2.6 ks exposure) and at T+578 ks, with count-rate (2.5+/-0.8)E-3 counts/s (6.9 ks exposure). Extrapolation from these two points gives a power-law decay index of 1.3 +/- 0.4 (1-sigma CL) for the afterglow. This Circular is an official product of the Swift-XRT team.

Circular_text TITLE: GCN CIRCULAR NUMBER: 7870 SUBJECT: GRB 080603A: Late-time Keck imaging and spectroscopy DATE: 08/06/13 00:28:58 GMT FROM: Daniel Perley at U.C. Berkeley D. A. Perley, J. S. Bloom, A. A. Miller, J. Shiode, J. Brewer, D. Starr, and R. Kennedy (UC Berkeley) report: On the night of 2008-06-07 (UT) we re-observed the location of GRB 080603A (GCN 7790, Paizis et al.) with Keck I / LRIS in g and R filters for 785s and 690s respectively, starting at 12:30 UT. The optical afterglow (Gomboc et al., GCN 7788; Chornock et al., GCN 7789) is well-detected as the northern member of a complex of sources. Calibrating relative to four nearby USNO B1.0 stars we estimate an afterglow magnitude of R = 23.7 +/- 0.1 (t = 4.05 days) The extended source reported by Rymyantsev et al. (GCN 7860) is clearly detected and is well-resolved into the afterglow plus two extended sources in the g-band frame, with the southern source significantly redder than the afterglow and the faint western source. A color image of the field is posted to: http://lyra.berkeley.edu/~dperley/080603a/080603a_color.png Given the very strong absorption lines reported in our spectroscopic observations (Perley et al., GCN 7791), this complex may be a bright host galaxy of this burst, as suggested by Rumyantsev et al. However, the sources above are offset significantly from the afterglow (which itself is not obviously extended), suggesting instead that they may represent one or both of the intervening absorbers. Later the same night, we acquired 2x900s spectra using a slit covering the northern (afterglow) source and southern source, and an additional 1x600 spectrum using a slit covering the faint western source and the bright, clearly separated eastern source noted by Kann et al. (GCN 7822). No obvious emission lines are evident in any spectrum. At any of the host and absorber redshifts of z=1.688, z=1.563 and z=1.271 respectively, the bright potential emission features (Ly-alpha, OII) are expected to fall outside our wavelength coverage, on top of sky lines, or be strongly attenuated by the atmosphere, so this result is mildly supportive of an association of these sources with the host and/or absorbers. However, the integrations were relatively short, and further follow-up is warranted.

At the place of the optical afterglow (Gomboc et al., GCN 7788; Chornock et al., GCN 7789) we detect an object with coordinates RA(J2000): 18 37 38.02 Dec(J2000): +62 44 39.44 Within uncertainties (0.5" or better ) the coordinates of the object are consistent with reported early (Gomboc et al., GCN 7788; Chornock et al., GCN 7789) and one can consider the object as afterglow of GRB 080603A. A group of two extended sources (Perley et al., GCN 7870) is not resolved in our later observation on 3.496 d (Rumyantsev et al. GCN 7860). The unresolved source (Rumyantsev et al. GCN 7860) lies ~1.8" south from the afterglow position. And tentatively one can consider the upper limit of the observation on 3.496 days R=22.85 (3sigma) as an upper limit of the afterglow brightness. Based on USNOB1.0 star with ID 1527-0313986 at RA = 18:37:55.186, Dec. +62:45:32.28 (R1 = 16.74) we estimated brightness of the afterglow on 1.521 days: UT, Exposure, R_mag, UL (mid time) 1.521 d 27x120 s 22.2 +/- 0.2 22.9 This message may be cited.

The afterglow is detected in each frame of 120 s exposure. Coordinates of the afterglow obtained from a combined image are R.A.(J2000) = 18 37 38.04 Dec.(J2000) = +62 44 39.4 with uncertainties of 0.3". A photometry of the afterglow obtained against several USNO-A2.0 stars is following: T0+ Exposure R_mag (mid) 0.3015 d 8x120 s 20.49 +/- 0.03 The photometry might be slightly contaminated by the nearby source(s) (Perley et al., GCN 7870, Rumyantsev et al., GCN 7860). In comparison to the magnitude measured in early epoch (Perley et al. GCN 7791) the index of power law decay is ~ 0.5 which is compatible with slow decay index (alpha ~ 0.5) obtained by Kann et al.
