Prepare for the partial solar eclipse of March 29, 2025

Attention, astronomy enthusiasts! On March 29, 2025 , Spain will witness a partial solar eclipse that promises to be a celestial spectacle worth admiring. This astronomical event will be visible throughout the country, with variations in magnitude depending on the location.

Details of the Partial Eclipse of March 29, 2025

On the morning of Saturday, March 29, the Moon will partially cover the solar disk, offering a unique opportunity to observe this phenomenon. According to the National Astronomical Observatory, the eclipse will have a magnitude greater than 0.4 in the northwest of the Iberian Peninsula, greater than 0.3 in the Canary Islands and the western Iberian Peninsula, and greater than 0.2 in the eastern Iberian Peninsula and the Balearic Islands.

For example, in Santa Cruz de Tenerife, the eclipse will begin at 10:15 a.m., reach its maximum at 11:04 a.m., and end at 11:56 a.m. (Spanish mainland official time; one hour behind in the Canary Islands). In other locations, the timing and magnitude will vary, so it is recommended to consult the specific tables provided by the National Astronomical Observatory for detailed information based on your location.

Safe Observation

It's important to remember that direct observation of the Sun without adequate protection can cause irreversible eye damage. To enjoy the eclipse safely, use solar viewing glasses that comply with the international standard ISO 12312-2 or employ indirect projection methods. Avoid using homemade filters or ordinary sunglasses, as they do not offer the necessary protection.

Upcoming Total Solar Eclipses Visible from Spain

While partial eclipses are fascinating events, total solar eclipses provide an even more impressive experience. After more than a century without a total eclipse visible from the peninsula, this trend will change in the coming years:

• August 12, 2026 : A total solar eclipse will be visible in a band crossing Spain from west to east, passing through cities such as La Coruña, León, Bilbao, Zaragoza, and Valencia. It's important to note that this phenomenon will occur near sunset, so it's recommended to look for locations with a clear view to the west for optimal viewing.
• August 2, 2027 : Another total eclipse will cross the southern tip of the Iberian Peninsula, including locations such as Cádiz, Málaga, Ceuta, and Melilla. This event will occur during the morning, offering a totality duration of up to 4 minutes and 48 seconds in some areas.

Additionally, on January 26, 2028 , an annular eclipse will occur that will be visible from various regions of Spain, adding another significant astronomical event to the calendar.

Preparation for Observation

To make the most of these astronomical events, it's a good idea to plan ahead. Make sure you have the proper equipment, such as certified solar observing glasses and solar filters for telescopes and cameras, and check the forecasted weather conditions for the eclipse date. Also, familiarize yourself with the specific times and path of the eclipse based on your location to select the best viewing site.
