In March 2019, skywatchers around the world were treated to a spectacular supermoon event that highlighted the year's closest new and full moons. This supermoon in March 2019 was especially notable because it reached peak fullness within hours of lunar perigee, producing a larger and brighter appearance than an average full moon.
Below is a detailed overview of the March 2019 supermoon, including timing, visibility, and photographic tips to help you plan your observations.
| Event | Date (UTC) | Phase | Moon Distance from Earth | Apparent Size Increase |
|---|---|---|---|---|
| Supermoon Full Moon | March 21, 2019 | Full Moon | 357,286 km | Up to 14% larger |
| Lunar Perigee | March 21, 2019 | Not visible | 356,777 km | Closest approach of the month |
| New Moon (near perigee) | March 8, 2019 | New Moon | 358,000 km | Not visible from Earth |
Understanding Supermoon Phenomena
What Makes a Supermoon
A supermoon occurs when a full or new moon coincides with or comes very close to lunar perigee, the point in the Moon's elliptical orbit nearest to Earth. During March 2019, the full moon on March 21 appeared noticeably larger and brighter, though the difference is subtle to the naked eye compared to a typical full moon.
Orbital Mechanics Involved
The Moon's orbit around Earth is not a perfect circle but an ellipse, with an average eccentricity of about 0.0549. This means the distance between Earth and Moon varies by roughly 40,000 km over the course of a month, affecting apparent size and brightness during full or new moon phases.
Visibility and Observation Tips
Best Times to View
For observers in the Northern Hemisphere, the March 2019 supermoon rose in the east soon after sunset on March 20 and remained visible through the night. Clear skies and minimal light pollution significantly improved viewing conditions for detailed observations of lunar craters and seas.
Photography Techniques
Photographers used longer focal lengths to capture details of the supermoon, while smartphone users benefited from using tripod mounts or steady surfaces to reduce motion blur. Proper exposure settings and avoiding excessive digital zoom helped retain the moon's natural texture against surrounding landscape features.
Cultural and Scientific Significance
Historical Naming Conventions
Although the term supermoon is modern, cultures around the world have long noted full moons that occurred near perigee. In March 2019, some traditions linked this full moon with themes of rebirth and seasonal planting, aligning with early spring in the Northern Hemisphere.
Scientific Research Context
Scientists tracked the March 2019 supermoon to refine models of lunar orbit and tidal forces. Precise measurements of lunar distance during perigee help improve satellite navigation systems and contribute to long-term studies of Earth-Moon dynamics.
Planning Future Moon Events
Upcoming Supermoon Patterns
Following March 2019, subsequent supermoon cycles continued throughout the year, with each new or full moon near perigee offering another opportunity for observation. Tracking lunar calendars helps enthusiasts anticipate similar events with comparable visibility conditions.
Community Engagement Activities
Local astronomy clubs and science centers organized viewing sessions during the March 2019 supermoon, providing telescopes and educational materials. These events encouraged public interest in lunar science and inspired observers of all ages to explore the night sky more frequently.

FAQ
Reader questions
How close did the March 2019 supermoon get to Earth?
The moon reached lunar perigee at 356,777 km on March 21, 2019, making it one of the closest approaches of that year and contributing to its enhanced apparent size.
Was the March 2019 supermoon visible worldwide?
Yes, the full moon phase was visible from most inhabited regions, though optimal viewing depended on local weather conditions and the position of the moon in the sky during nighttime hours.
Can a supermoon affect tides more than a regular full moon?
During a supermoon, the combination of full moon phase and lunar perigee produces slightly higher than average tides, particularly in coastal areas, due to the stronger gravitational pull of the closer moon.
What equipment is best for photographing a supermoon?
A telephoto lens with focal lengths of 200 mm or longer, a sturdy tripod, and cameras with manual exposure controls work best. Smartphone adapters and image-stabilization features also help capture sharp, detailed photos of the supermoon.
