Nadine and I live on the top floor of an apartment building that is not exactly a rectangle in floor plan, but each floor does have one main long central hallway. At either end of the hallway, there is a steel fire door to the balcony outside, and each door has a small window in it.
In our building, this hallway is on an east/west axis. Thus, on the equinoxes (twice per year), at sunrise when the sun rises directly in the east, and again at sunset when the sun sets directly in the west, the rays of the sun stream thru one of these windows, and shine all the way down to the other end of the hallway
Here are two time-lapse videos, made on my iPhone with the Frameography app, that show these occurrences yesterday. (Today is actually the autumnal equinox, but yesterday was close enough, and both sunrise and sunset were clear, and the smoke in the air is mostly gone). In each case, the camera starts out at the east end of the hallway, looking towards the door at the west end. Your will also get very fleeting glimpses of some of our neighbors and their pets.
Each video is about one minute in length, and represents about 80 minutes of elapsed time. Please excuse the rather crude photography on my part, but I think you will get the picture.

Sunset, Sept 19, 2020:
As we struggle with all of our human fears and problems, of which we have so many at this time, the Earth continues to circle around its Sun, and rotates on its tilted axis, giving us these seasons and equinoxes and solstices, unchanging...and unconcerned.
