Solar Eclipse, Spring Equinox and New Moon: March's Celestial Triad
Solar Eclipse, Spring Equinox and New Moon: March's Celestial Triad
Sep 21, 2024 8:43 AM

Friday, March 20 brings with it a celestial showcase, a trio of events that includes a new moon, at 5:36 a.m., a total solar eclipse, at 5:46 a.m. and the vernal equinox, at 6:45 p.m., all Eastern time. Let’s tackle these one at a time, with the rarest of the three first.

Total Solar EclipseIf you happen to be on the Faroe Islands or the Svalbard Archipelago (Norwegian islands in the Atlantic Ocean), there’s a decent shot the total solar eclipse will be overhead — weather-depending, of course.

“The North Atlantic is a , no more so than in March,” writes Eclipser, a University of Manitoba site devoted to all-things eclipse. Unfortunately, it won’t disappoint in that respect tomorrow, according to Chris Dolce, a digital meteorologist for weather.com.

For this eclipse, some clouds Friday morning around the Faroe Islands could hamper viewing, though they may break at times, Dolce said. “For the partial eclipse,” he added, “at least scattered cloud cover will be in place over Ireland, the northern U.K. and Scandinavia. Portions of central Europe, including Germany and Poland, will have mainly clear skies.” Only twice in the past 40 years, in 1979 and 1991, has a been visible from the United States.

Scientifically speaking, what causes a solar eclipse? “You get kind of the opposite of the lunar eclipse,” Jim O’Leary, senior scientist at the , told weather.com in October 2014. “As [the moon] orbits the Earth, it’s slowly passing in front of the sun. It’s blocking part of the sun.”

Or in the case of tomorrow’s eclipse, the whole sun, but just for , according to NASA. It’ll take about two hours to move into and out of that position, however, so there’s definitely time for a view. It will be pretty early morning, with peak happening at around 9 a.m. Universal Time, which is 5 a.m. Eastern time.

Remember, never look directly at the sun but rather use an obstruction like a pinhole projector. Here are details on how to , even in its partial state.

New MoonThe month already had its full moon, back on March 5, but tomorrow brings with it the new moon, which means the moon sits precisely between the Earth and the sun. It’s when the lunar cycle starts over, essentially. NASA has a great, easy way to , with just a few household items.(For the full demonstration, click .)

You will need a lamp and a small ball (like a tennis ball or a softball). If the lamp has a shade, take it off. Pretend the lamp is the sun, the ball is the moon, and your head is Earth. Darken the room except for the lamp. Now, hold the ball straight out in front of you. Stand facing the lamp. The ball will appear dark because the lighted side of the ball is facing away from you. This position represents the New Moon, dark and about to be born.

Vernal EquinoxFinally, March 20 is also when the calendar flips to “spring,” . “This year, the takes place … at 6:45 p.m. EDT,” weather.com digital meteorolgists reported. “At this time, the sun is crossing over from the southern hemisphere into the northern hemisphere. During this process, the sun is shining directly over the Earth’s equator, bathing the Earth’s northern and southern hemispheres in nearly an equal amount of sunlight.”

Sure, the vernal equinox signifies the end of winter, but will temperatures actually feel like we’re starting a new, warmer season? Sadly, three separate weather systems are in play across the country. As of Thursday afternoon, were impacting 32 million people in the Northeast.

“Wet snow spreads from central/northern Pennsylvania and southern New York to southern New England,” wrote weather.com digital meteorologist Jon Erdman. “Slush buildup on roads is possible for the morning [Friday] and afternoon commutes, particularly in the Philadelphia and New York City metro areas.” Friday night doesn’t look much better, with more wet snow to come. The storm could reach as far as upstate New York and parts of northern New England.

Here’s hoping it’s the season’s last and spring truly is around the corner.
