1 Otero, Sebastian Alberto No star can be seen in Pan-STARRS1 images at the ASAS-SN position. There is a ZTF transient object (ZTF18ablutpo) at the position of the 19.0 Vmag. star 4" to the S but with single detections, more reminiscent of a flare star. J-K= 0.91 (2MASS), and Pan-STARRS1 and Gaia colours indicate that it is too red for a dwarf nova, but the Gaia EDR3 parallax is 0.2382 (+/-0.2186). Unreliable? The same object is included in the list of Large-amplitude variables in Gaia DR2 (2021A&A...648A..44M). The ASAS-SN light curve shows both flares likely coming from ZTF18ablutpo and dwarf nova outbursts. Only the latter have been included in the corrected light curve.
2 Otero, Sebastian Alberto VSP Note: 21.0 mag. star 3" to the NW, 19.0 mag. star 4" to the S (flare star?), 18.6 mag. star 5" to the WNW and 15.6 mag. star 8" to the NNW.
