[vsnet-alert 25712] Re: ASASSN-21fh: possible nova (mag. 10.4) in Scorpius

ASASSN-21fh 210412.8139	10.635B	(0.002) FID

Position end figures 08s.11, 40".9 measured with a 0.50m f/6.8 reflector 
+ FLI-PL6303E CCD camera at Siding Spring, Australia (T30, iTelescope.NET).

Unfortunately the 10s V-band images were already saturated, but visual 
inspection of the images showed the nova candidate slightly brighter 
than 9.0 magnitudes. Thus B-V seems to be at least 1.5 magnitudes. The 
variable is indeed very red.
