Further to E-circulars 3717, 3718 Andrew Pearce, Nedlands, Western
Australia, reports his discovery of a nova-like variable (mag 10.7) on three
unfiltered images (limiting mag 12.5) taken on June 25.487 UT with a Canon
800D digital camera (+ 85-mm-f.l. f/1.2 lens), providing the following
approximate position:  

R.A. = 15h24m44s.6, Decl. = -60d59'20" (equinox J2000.0).  

Pearce comments that there does not appear to be any evidence of significant
variability of the Gaia DR3 source mentioned by Romanov in the ASAS-SN data
going back some years, though this variable could be an object close to that
14th-magnitude star.

Pearce forwards a report that T. Love, Martinborough, New Zealand, obtained
a low-resolution (R about 600) spectrogram on June 26.946 UT using a 30-cm
Ritchey-Chretien telescope (+ Shelyak Alpy spectrograph); the spectrum shows
a reddened continuum and strong emission with a heavily broadened base in
hydrogen Balmer lines and in He I lines at 492.2, 501.6, 504.8, 587.6, and
706.5 nm.  P-Cyg line profiles are weak or absent.  The full width of the
base of the H-alpha line was approximately 32.0 nm, or around 14600 km/s,
giving an estimated velocity of over 7000 km/s for the ejecta.  The spectral
features and radial velocity are consistent with the object being a fast He
nova after maximum brightness.

E. Kazarovets writes that the permanent GCVS designatino FQ Cir has been
given to TCP J15244460-6059200.
