Observe Ursa major at the same time on different nights, see how his position moves with time, and draw what you observe.

It took me half an hour to draw this. From top to bottom, I drew from north to northwest according to what I saw in April 10, May 10 and June 10 this year. The time is 22 o'clock in the evening. I also added a line between the stars to make him look more like a bear.

The one at the bottom is more like a bear with its head down and tail up.

I draw them all on the computer, which is very beautiful and clear. Please adopt it in time.
