Spring equinox enhances visibility of aurora borealis

This week marks the start of spring in the Northern Hemisphere, with the vernal equinox occurring on March 20. Winter stars like Orion are fading, while spring constellations such as Leo, Boötes, and Virgo are becoming more prominent. The equinox may also enhance the visibility of the aurora borealis due to the alignment of Earth's magnetic fields and solar wind. This phenomenon can lead to more intense displays of the Northern Lights. Sky-watchers can look for the "spring triangle" of stars on March 17 and enjoy a last quarter moon on March 22, which will provide dark skies for stargazing. Ursa Major, visible year-round, is highlighted as a notable constellation.
