Sorry, there was a typo, but I cannot edit the original post. So instead of ATEL 5213 the symbiotic nature of the object was described in ATEL 5215:

A brand new AAVSO chart with sequence for this symbiotic nova is now available from VSP. You just need to type: VVV-NOV-003

According to the observations I have been fortunate enough to make, this object has decreased from 12th to 13th magnitude in V. The B-V color is currently estimated to be +0.72 (slowly increased). The most impressive change I'm seeing right now is the large and rapid increase in the V-Rc index up to +1.53 from +0.55 between July 20.599UT and July 22.202UT. The Rc-Ic indice is a relatively modest +0.56.

This object carries the AUID '000-BLC-300' in VSX, or simply BLC-300 as I like to call it.

Plenty of change here!  The V mag is back up to 12.5 (I saw 13.3V a couple of nights ago). The B-V is remaining quite stable at around +0.7 but the V-Rc, having rapidly increased to about +1.5 a couple of nights ago has just as quickly returned to the +0.6 level.

kind regards,

Steve

I took a follow up spectra of this star tonight. It is very interesting with strong H lines plus Fe lines.
