Magnier, C. Waters, J. Bulger, R. J. Wainscoat (IfA, Hawaii), D. Wright, (Univ. of Minnesota) report:
Following on from Paterson et al. (GCN 26360), we report previous Pan-STARRS1 (Chambers et al. 2016) detections of the transient SAGUARO19j, dating back to 2019 Nov 29. We have 4 detections at the location of the transient (RA = 23:15:56.35, Dec = +10:41:01.2) as detailed below, all in the PS1 w-band filter:
MJD | Magnitude | Error
58816.3377791 | 20.4147 | 0.120339
58816.3275293 | 20.4336 | 0.0684682
58816.3172459 | 20.4022 | 0.082446
58816.3069985 | 20.3953 | 0.0836078
These PS1 detections were registered as a unique object to the TNS with the identifier AT2019wdb. As such, we do not believe this object is associated with S191205ah.
