It was quite cool last night. Time to bring in my houseplants that have been vacationing outside. My wife put on the heat this morning to take out the chill in the air. Last week the air conditioning was on. We must be at the autumnal equinox.
For two moments each year the Sun is exactly above the Equator and day and night are of equal length. Here in the Northern Hemisphere, the autumnal equinox occurs on September 22 or 23. For 2020, it is Tuesday the 22nd. (In the Southern Hemisphere it was in March when we marked spring.)
No matter what the weather is in your corner of the world, a new season is beginning that will last until the next solstice in December.
The autumn tree foliage is brilliant and so is another autumn show. The aurora borealis, also called the Northern Lights, now are more likely to appear because geomagnetic storms are about twice as frequent as the annual average during the autumn.
