A transient object has been discovered near NGC 6907 as part of the Pan-STARRS Survey for Transients (PSST).
Information on all objects discovered by the Pan-STARRS Survey for Transients is available at http://star.pst.qub.ac.uk/ps1threepi/

Name | RA (J2000) | Dec (J2000) | Disc. Date | Disc Mag | filter | Notes
PS15bjv | 20 25 03.85 | -24 49 13.6 | 20150724 | 20.58 | w | (1)
The object is 55.5" from the core of NGC 6907 (z=0.011224, luminosity distance ~ 40 Mpc). The major/minor axis of the edge-on galaxy is ~3', making this well within the disk, and there is no extended source at or near the position of the transient. Assuming that the object is associated with NGC 6907, its absolute magnitude at discovery would be ~ -12.5.
The object subsequently appears in i-band PS1 data on 20150727.45 and in r-band Liverpool Telescope data on 20150728.00. It does not appear to have changed significantly in brightness during this 3.5 day period. It is not detected in PS1 data taken of this field between 754 and 444 days before discovery. Optical spectroscopy of this object is encouraged.
