The Quadrantids are among the most notable meteor showers, occurring annually and revealing splendid displays of shooting stars to the eager observer. As we usher in 2025, both amateur and seasoned astronomers are gearing up to witness an astronomical spectacle featuring the Quadrantid meteors at their peak, as well as Earth reaching its perihelion, and a lunar occultation of Saturn.
As 2025 begins, a vast array of celestial events presents itself to those willing to look up. The first weekend is particularly exciting, not only for the Quadrantids but for various planetary interactions and our planet’s movement relative to the sun.
January's 'Quad Watch'
The Quadrantids peak on January 4th, boasting a respectable projected Zenithal Hourly Rate (ZHR) of 80. Unlike previous years, the observed moon phase is also favorable; a waxing crescent moon, illuminated at 27%, will not hinder observations, rendering 2025 an exemplary year for observing the Quads.
Prospects in 2025
The peak activity is anticipated between 15:00-18:00 Universal Time on January 3rd, which primarily favors the northern Pacific region at dawn. Observers in North America and Europe are urged to remain vigilant on the mornings of January 3rd and 4th, as activity may extend beyond the estimated peak.
The seldom-acknowledged name for the Quadrantids reflects a remnant of the now-defunct constellation Quadrans Muralis (the Mural Quadrant), which was divided among Draco, Hercules, and Boötes when modern constellations were formally designated by the International Astronomical Union (IAU) in 1928. The historical significance of this naming makes the occurrence of this meteor shower truly fascinating.
Many enthusiasts have discovered that while the Quadrantids comprise a robust stream, they often prove elusive due to the brevity and swiftness of their peak activity. This year’s array of activities allows for a broader window for ice-cold skywatching.
To fully relish the Quadrantid meteor shower, one should ensure warm clothing, prepare a travel mug filled with tea or cocoa, and safeguard backup camera batteries against the frigid January air.
Earth at Perihelion
Simultaneously, as the Quadrantids streak through the sky, our planet will reach perihelion—its closest distance to the Sun—on January 4th, at approximately 0.98333 AU. The perihelion event will occur around 13:00 UT or 8:00 AM EST in 2025. It is intriguing to note that such a close proximity occurs during the depth of winter in the northern hemisphere while it is summer in the southern hemisphere.
This phenomenon emphasizes how the parameters of Earth's orbit—such as eccentricity, axial tilt (obliquity), and precession—change over time through what are referred to as Milankovitch cycles. An interesting fact emerges; the Sun appears slightly larger in the January sky (32’ 32” in apparent size) than it does during aphelion in July (31’ 28”). The contrast in angular size reinforces the dynamic nature of Earth's motion in our solar system.
A ‘Great European Occultation’
Moreover, on January 4th, observers will also witness the Moon occulting Saturn at approximately 17:24 UT. This remarkable event bestows favor upon European observers at dusk, as a 25% illuminated crescent moon presents itself—a prime opportunity for observing an occultation event. This occurrence marks the first planetary occultation by the moon in 2025.
This celestial display will be extraordinary, as Saturn—the 39” wide planet, including its rings—will leisurely disappear behind the dark limb of the Moon, only to reemerge behind its sunlit side approximately 45 seconds later. As Saturn's rings edge closer to being edge-on, minimal visibility will be evident, yet observers can still catch a breathtaking view of the planetary pairing with the crescent Moon at dusk worldwide.
In totality, the Moon will occult Saturn twice within 2025— the second occurrence poised for February 1st, favoring observers in remote regions of the Canadian Arctic and Alaska. The International Occultation Timing Association offers ingress and egress times specific to locations along this track for the January 4th event.
...And Something More
Caught in clouds? Or perhaps residing in a less favorable hemisphere? Renowned astronomer Gianluca Masi will host a trio of virtual events this weekend, centering around the Quadrantid meteors, the Moon's occultation of Saturn, and the Moon’s close encounter with Venus on January 3rd—just prior to its grand dusk elongation at 47 degrees east of the Sun on January 10th:
As the Moon joins this captivating planetary ensemble, it will glide by Saturn and Venus at dusk. Meanwhile, Jupiter and Mars anticipate their turn in the east, ready to greet the Moon as January progresses.
Wherever your observational point may be this weekend, numerous celestial events await your gaze. Dress warmly, embrace the chilly climate, and prepare for excellent skywatching as we ring in another exciting year in astronomy.
