Obvious "Dip" started around 20. May 2024 ( Gold arrow). If a "Dip" precede an outburst with approximately 9 months, then we should expect a Nova around 20. February 2025, and that is also 79 years after the eruption in February 1946.

Before 1946, we had a nova approximately 80 year earlier, in 1866.
And in 1787, approximately 79 years earlier.
