Could Andromeda be at its zenith for latitude 60 ° on September 20th? What time?

constellation Andromeda
Right ascension from 22h 52m to 2h 31m
Declination 21 to 52.5 °
No, it cannot, since it can be at its zenith only for latitudes up to 52.5. However, we can conditionally call the zenith the culmination of some midpoint of the constellation. September 20 is about six months after the vernal equinox. On the vernal equinox, the sunrise is at about 0:40 (local time), which means September 20 at about 12:40, and therefore the climax at 18:40.
