Object visible in four frames taken with Canon 650D & 55mm lens by Rob Kaufman, Bright, Victoria, Australia; astrometry approximate only. Visible in follow-up frames taken approx 2 hrs later and a low-resolution spectrum shows strong hydrogen emissions as well as FeII lines.

Daniel Bamberger determined the following position from Rob Kaufman's discovery image as follows: 11 26 15.92 -65 31 25.3 (J2000.0; accuracy about 20"). According to ASAS-SN Sky Patrol observations (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) – using the position determined by Bamberger – this nova eruption apparently began between 2018 January 1.25 and 3.24 UT (maximum brightness V= 8.8 mag on Jan. 3.24 UT): https://asas-sn.osu.edu/light_curves/87fd7dc5-af64-42aa-9f2e-59b05de938f9 --- Patrick Schmeer (Saarbrücken-Bischmisheim, Germany)

Improved astrometry (1" accuracy) by Daniel Bamberger using three CCD images taken by Róbert Fidrich (instrument: T13 at the iTelescope network): RA 11h26m15.16s, DEC -65°31'23.3" (J2000.0). A Gaia DR1 source (G= 18.02 mag) is located 1.3" from this position. --- Patrick Schmeer (Saarbrücken-Bischmisheim, Germany)

Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Musca (TOCP Designation: PNV J11261220-6531086) we performed some follow-up of this object through a TEL 0.50-m f/6.8 reflector + CCD + focal reducer from MPC Code Q62 (iTelescope Observatory, Siding Spring). On images taken on January 15.57, 2018 we can confirm the presence of an optical counterpart with R-filtered CCD magnitude ~6.3 at coordinates: R.A. = 11 26 14.95, Decl.= -65 31 24.1 (equinox 2000.0; Gaia DR1 catalogue reference stars).

Following the possible Nova in Musca (TOCP Designation: PNV J11261220-6531086) I performed one follow-up of this object through a TEL 0.431-m f/6.8 reflector + CCD from MPC Code Q62 (iTelescope Observatory, Siding Spring). On images taken 2018/01/15 UT17:01 , I can confirm the presence of an optical counterpart with V-filtered CCD magnitude ~7.4 at coordinates: R.A. = 11 26 14.94 , Decl.= -65 31 24.9 (J2000.0; Gaia DR1), Adriano Valvasori (Italy) - https://flic.kr/p/228Xp46
