Dear colleagues,
Fidrich Robert, thank you very much for your research on ASAS-3 data.
Here are some additional information and observations.
DSS images:

My measurement from the DSS images:
1951 July 11 20.7B
1951 July 11 17.8R
1990 July 20 17.5B
1993 July 25 16.7R
1996 July 17 15.6I
I found this star is recorded in USNO-B1.0 as:
USNO-B1.0 1128-0406315 18h46m37s.4673 +22o48'22".240
17.830(R1) 16.940(B2) 16.250(R2) 15.140(I2)
Hidetaka Sato observed this star at RAS Observatory, Mayhill, using
0.25-m f/3.4 reflector with ST-10XME, as follows:
R.A. 18h46m37s.48
Dec. +22o48'22".3
mB = 17.23 +- 0.07
mV = 15.13 +- 0.01
mR = 13.73 +- 0.05
which shows this star is red as B-V = 2.10, V-R = 1.40.
Best regards,
