The upcoming total solar eclipse in September 2025 is a highly anticipated astronomical event, offering a spectacular celestial display for observers in specific regions. This eclipse, occurring on September 21, 2025, will be visible as a total eclipse along a narrow path stretching across parts of the globe, while other areas will experience a partial solar eclipse. The event promises to be a significant opportunity for both seasoned eclipse chasers and casual skywatchers to witness the awe-inspiring phenomenon of the moon completely obscuring the sun.
Understanding Solar Eclipses
Solar eclipses are captivating astronomical events that occur when the Moon passes between the Sun and Earth, casting a shadow on our planet. This alignment happens during the New Moon phase, when the Moon is not visible from Earth under normal circumstances. However, a solar eclipse is only possible when the Moon, Sun, and Earth are precisely aligned in a straight line, or very close to it. Because the Moon's orbit is tilted relative to Earth's orbit around the Sun (the ecliptic), solar eclipses don't happen every month. Instead, they occur sporadically, making each event a unique and eagerly awaited spectacle.
There are several types of solar eclipses, each distinguished by the degree to which the Moon covers the Sun. A total solar eclipse is arguably the most dramatic, occurring when the Moon completely blocks the Sun's bright face, revealing the Sun's faint outer atmosphere, or corona. This creates a breathtaking sight, turning day into a twilight-like darkness for a few precious minutes. During totality, observers can often see stars and planets in the darkened sky, adding to the surreal experience. The path of totality, the narrow strip on Earth where the total eclipse is visible, is the most sought-after location for eclipse viewing.
Alternatively, a partial solar eclipse occurs when the Moon only partially covers the Sun's disk. This type of eclipse is more common than a total eclipse and can be seen over a much wider area. During a partial eclipse, the Sun appears to have a dark shadow on a portion of its surface, resembling a crescent shape. While a partial eclipse is interesting to observe, it doesn't offer the same dramatic effects as a total eclipse. Special eye protection, such as eclipse glasses, is crucial when viewing a partial eclipse to prevent eye damage.
An annular solar eclipse is another type, happening when the Moon is farther away from Earth in its orbit, making it appear smaller in the sky. In this case, the Moon doesn't completely cover the Sun, leaving a bright ring, or annulus, visible around the Moon's dark disk. The sight of the "ring of fire" is a stunning spectacle, but like partial eclipses, it requires proper eye protection to view safely. Annular eclipses are less common than partial eclipses but offer a unique visual experience.
A hybrid solar eclipse is the rarest type, combining elements of both total and annular eclipses. This occurs when the curvature of the Earth causes the eclipse to appear as a total eclipse in some locations and an annular eclipse in others along the path. Hybrid eclipses are fascinating because they showcase the dynamic nature of celestial mechanics. Understanding these different types of solar eclipses helps enthusiasts and the general public alike appreciate the complexity and beauty of these astronomical events. — BYU Vs.

Safety Precautions for Viewing a Solar Eclipse
Viewing a solar eclipse is an extraordinary experience, but it's crucial to prioritize eye safety. Looking directly at the Sun, even during a partial eclipse, can cause serious and permanent eye damage. The intense solar radiation can burn the retina, leading to a condition called solar retinopathy. This damage can occur without any immediate pain, making it even more insidious. Therefore, adopting the correct safety measures is essential to protect your vision while enjoying the celestial spectacle.
The primary rule for safe solar eclipse viewing is to never look directly at the Sun without proper eye protection. Standard sunglasses, no matter how dark, are not sufficient. They do not block the harmful rays that can damage your eyes. Instead, you need specialized eye protection designed specifically for solar viewing. This typically comes in the form of eclipse glasses or handheld solar viewers that meet the ISO 12312-2 international safety standard.
Eclipse glasses are similar in appearance to cardboard-framed 3D glasses but contain special filters that block out nearly all of the Sun’s intense light and harmful ultraviolet and infrared radiation. These glasses allow you to look directly at the Sun during the partial phases of the eclipse without risk. When purchasing eclipse glasses, it’s vital to ensure they are certified and meet the ISO 12312-2 standard. Counterfeit or substandard glasses may not provide adequate protection and can lead to eye injury. Reputable vendors and science museums are reliable sources for purchasing safe eclipse glasses. Before using them, inspect the glasses for any scratches or damage; if they are damaged, discard them.
Handheld solar viewers work on the same principle as eclipse glasses, using special filters to make it safe to look at the Sun. These viewers are typically rectangular cards with a small viewing area containing the filter. Like eclipse glasses, they must meet the ISO 12312-2 standard. Always hold the viewer in front of your eyes and look through the filter when viewing the Sun. Avoid using homemade filters or other uncertified devices, as they may not provide adequate protection.
An alternative method for safe viewing is indirect projection. This technique involves projecting an image of the Sun onto a surface, allowing you to view the eclipse without looking directly at the Sun. One simple method is to use a pinhole projector. Create a small hole in a piece of cardboard using a pin, then stand with your back to the Sun and hold the cardboard so that sunlight passes through the hole. The image of the Sun will be projected onto another surface, such as a wall or the ground. You can also use binoculars or a telescope to project a magnified image of the Sun onto a white screen, but this method requires careful setup and should only be done by someone experienced in using optical equipment for solar viewing.
During the brief period of totality in a total solar eclipse, when the Sun is completely blocked by the Moon, it is safe to look at the eclipse with the naked eye. This is the only time when direct viewing is safe, as the harmful rays of the Sun are completely obscured. However, it’s crucial to know exactly when totality begins and ends. Use eclipse glasses or a solar viewer until the moment of totality, and put them back on as soon as the first sliver of the Sun reappears. Misjudging the timing can result in eye damage.
Following these safety precautions ensures that you can fully enjoy the spectacular experience of a solar eclipse without risking your vision. Remember, the beauty of the eclipse is best appreciated with healthy eyes.

Equipment: To photograph a solar eclipse effectively, you'll need certain key pieces of equipment:
- Camera: A DSLR or mirrorless camera with manual mode capabilities is ideal, as it allows you to control settings like aperture, shutter speed, and ISO.
- Lens: A telephoto lens with a focal length of at least 300mm is recommended to capture a detailed image of the Sun and the eclipse. For even better results, consider lenses with focal lengths of 500mm or more.
- Solar Filter: As mentioned earlier, a solar filter is essential for safe photography during the partial phases of the eclipse. Ensure it is specifically designed for solar viewing and fits your lens securely.
- Tripod: A sturdy tripod is crucial for keeping your camera stable, especially when using long telephoto lenses. This will help prevent blurry images caused by camera shake.
- Remote Shutter Release: Using a remote shutter release or the camera's self-timer minimizes vibrations when taking photos, resulting in sharper images.
Planning Your Shots: Before the eclipse, scout your location and plan your shots. Consider the composition, foreground elements, and the position of the Sun in the sky. Use a solar eclipse calculator or app to determine the exact timing of the eclipse phases at your location. This will help you be prepared for each stage of the event. — Countdown To July 9th: How Many Days Are Left?
Camera Settings: During the partial phases, with the solar filter on, start with a low ISO (such as 100 or 200), a narrow aperture (f/8 to f/16), and a fast shutter speed (1/500 to 1/1000 second) to prevent overexposure. Adjust these settings as needed based on your specific equipment and lighting conditions. It’s a good idea to take test shots before the eclipse begins to fine-tune your settings.
During totality, when you remove the solar filter, you’ll need to adjust your settings significantly. The corona is much fainter than the Sun's surface, so you’ll need to increase your ISO (to 400 or higher), widen your aperture (f/4 to f/8), and use a slower shutter speed (1/60 to 1 second). Experiment with different settings to capture the various features of the corona, such as the streamers and prominences.
