The position of Beiluo Shimen when it appeared.

Tonight at 20: 13, you can see Beiluo Shimen passing due south in Wenzhou, with a height of 32.5 degrees. At this time, Jupiter is at a height of 40 degrees southwest (30 degrees west longitude when viewed from the south). Jupiter is very bright, and Beiluoshimen is a first-class star, much darker than Jupiter, but there are no other bright stars around, so it is easy to identify.
