[vsnet-alert 25056] ASASSN-20pb - large-amplitude object

[Denis Denisenko d.v.denisenko@gmail.com via vsnet-alert]

I have obtained 6x60-sec unfiltered images of the field centered at
ASASSN-20pb remotely with 0.25-m f/4 reflector iTelescope.Net T05
instrument at Mayhill, NM. Here is the animation of three combined images
at 2020 Dec. 04.354 UT with POSS-II Red plate (2x zoom cropped to 5'x5'):

Indeed, this is an outburst from the faint background star not present in
any catalogs before. Spectroscopy, multi-color photometry and time series
are encouraged.
