TITLE: GCN CIRCULAR NUMBER: 45106 SUBJECT: Nova AT2026oyp (ASASSN-26dt): Pre-outburst Swift UVOT observation DATE: 26/07/07 17:06:06 GMT FROM: Paul Kuin at MSSL <npkuin@gmail.com> The LMC nova AT2026oyp (ASASSN-26dt) was observed by Swift UVOT in the UVW1 filter on 2017-11-14 in a 54. s exposure. That predated the eruption reported in ATEL #17878 (Chomiuk et al.) and the nova was reported to have peaked at g=10.5 mag on 2026 June 11. The quescent magnitude in the UVOT UVW1 filter was UVW1 = 19.56 +/- 0.26 (stat) +/- 0.03 (sys) (AB) mag consistent with the other reported quiescent values, at a position RA = 00h 50m 45.11s, Dec = -71d 38m 38.51s (J2000) with uncertainty = +/- 1.05" (90% confidence) marginally consistent with the reported position at RA=01:50:45.142, Dec= -71:38:36.96.
