Very good educated guess by Freddy Nauta.

My educated guess is 1.July 2025. I mentioned this approximate time in June 20th 2024 (link below), because there is evidence for a periodicity of approximately 79.5 years. The last eruption was in 9. February 1946 so add approx. 79.5 years.

The stated "Media-Dip" which was supposed to indicate a nova eruption in February/March 2023, is obviously wrong. This star has "Pre-Dips" all the time so I don't think any "Pre-Dip" is an indication of a nova eruption.
