PSN J12060084+2036183 and PSN J12054713+2025026: two possible supernovae at a glance (10 May 2015)
PSN J12060084+2036183 and PSN J12054713+2025026: an image (10 May 2015)
Last night, we wanted to image a region we already observed, when confirming – on two different nights – two possible supernovae: in an handful of days, in fact, two suspect transients have been found in the same spot of the sky: PSN J12054713+2025026 and PSN J12060084+2036183.
The picture above comes from the average of five, 180-seconds exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. Images were unguided, binning 2×2, with a resulting scale of 1.2″/pixel. Both the transients are visible: having two possible supernovae (still waiting at the time of writing of spectroscopic confirmation) in less than half-degree, is not common. PSN J12054713+2025026 and PSN J12060084+2036183 were found at mag. 19.3 and 17.9, respectively (R mags for the reference stars from UCAC-4).
