Grrr! Stellarium on my laptop and Stellarium on my desktop are giving me transit times that differ by an hour and I cannot see why. Doesn't matter. If the skies are clear, I'll just watch from about 9pm.
Here is the prediction for 18 min after midnight from Stellarium on my desktop, when all four Moons are over the surface for around 6 minutes!
(My laptop says this all happens one hour later. Yet both are set to the right location and both show the current time correctly
)
