EP240908a: Mondy and AbAO follow-up observations
Abstract
We observed the field of fast X-Ray transient EP240908a (Mao et al., GCN 37432) with AZT-33IK 1.5-m telescope of Mondy observatory, and AS-32 0.7-m telescope of Abastumani observatory (AbAO). The observations were started on 2024-09-08 at 19:05 UT at Mondy (~ 1 day since EP trigger). The series of images in the R-filter were taken. Preliminary upper limits are given below: Date UTStart JD Filter Exp. OT err UL(3sigma) Telescope (mid, days) (s) 2024-09-09 19:05:56 60562.82703 R 45x120 n/d n/d 23.5 AZT-33IK 2024-09-09 19:37:24 60562.84333 R 74x60 n/d n/d 19.7 AS-32 The magnitudes were calibrated with nearby USNO-B1.0 stars (R2 magnitudes). We do not resolve the optical source proposed by Quirola-Vasquez et al. (GCN 37438). In a stacke Mondy image we clearly detect a nearby LS DR10 elliptical source at RA=00:56:00.5 DEC=+08:04:33.2 which is apart of 3.6 arcsec from the proposed OT. This elliptical source might be a host galaxy of the EP240908a.
