Entering autumn
Astronomically autumn came on Sunday night September 23rd at 04.54 o’clock, or, when you woke up on Sunday morning it was already autumn.
We reached the equal day period but today the night was not yet longer than the day. But after the equinox the evening darkness arrives soon after sunset. Already within an hour we can see stars in the sky in clear weather where light pollution is slight.
This is a very strange year. Phenologically the start of autumn is considered to be the beginning of colouring of maple leaves (based on long-term observations - September 11th).
