Seems like it has started a dip, on 20. May 2024... If there is a correlation between a major eruption and a "major-dip", then we will have a nova approximately 9 months later. That is February – March 2025. That is also 79 years after the eruption in February 1946.
And we had a nova approximately 80 years earlier, 1866.
And in 1787, approximately 79 years earlier.
