The below table summarizes the results of the two nights: R.A. (J2000)= 17:27:43.32 Dec. (J2000)= -16:12:19.2 ----------------------------------------------------------------------------- ObsTime (mid), t(mid) – t(0) (hours), Exposure (sec), Filter, Mag ----------------------------------------------------------------------------- 2023-08-24T18:29:24Z, 04.5, 180s, R, 13.5 +/- 0.04 2023-08-25T16:29:44Z, 26.5, 180s, R, 13.0 +/- 0.01 ----------------------------------------------------------------------------- The observations were calculated using the Atlas catalogue as a reference and are not corrected for galactic extinction. The object is added to The International Variable Star Index catalogue and photometric observations can be submitted through AAVSO website.
