Sun calculation not working correctly for NZ? "Sun never transits at a zenith of 96.0 on 2020-02-11"

[therefromhere]

I'm getting this error with astral==2.0.1 (also with the 2.0.2 tag, and with latest master 60aa65f) when trying to calculate sun data from NZ:

"ValueError: Sun never transits at a zenith of 96.0 on 2020-02-11"

Example:

from astral.geocoder import database, lookup
from astral.sun import sun
import pprint

london = lookup("London", database())
pprint.pprint(sun(london.observer))

outputs something reasonable:

{'dawn': datetime.datetime(2020, 2, 11, 6, 47, 1, 656555, tzinfo=<UTC>),
 'dusk': datetime.datetime(2020, 2, 11, 17, 42, 13, 415600, tzinfo=<UTC>),
 'noon': datetime.datetime(2020, 2, 11, 12, 14, 14, tzinfo=<UTC>),
 'sunrise': datetime.datetime(2020, 2, 11, 7, 22, 40, 881412, tzinfo=<UTC>),
 'sunset': datetime.datetime(2020, 2, 11, 17, 6, 30, 837342, tzinfo=<UTC>)}

wellington = lookup("Wellington", database())
pprint.pprint(sun(wellington.observer))

hits this exception

I have uploaded version 2.1 which fixes this bug.

The problem was with sun times that in the UTC timezone that would be on the previous day and I was treating that as an error. This only showed up for time zones with a large positive time offset of which Wellington is one.

Thanks, I can confirm this is working for me now with 2.1.
