Monday’s pairing puts Venus beside a little more than 3-day-old crescent moon, still close enough by evening to form a striking low south-west view despite their nearest pass coming at lunchtime.
UK observers face a timing challenge because the closest approach happens in daylight; by 6:30 p.m. in London, the sun is still above the horizon and Venus may be hard to pick out at first.
The safest method is to find the thin crescent moon first and use it to locate Venus nearby, waiting as the sun drops lower while both objects sink toward the horizon.
Southern Hemisphere viewers get the same conjunction higher in the post-sunset sky, while Europe misses the daytime occultation visible from some other regions.
