On the evening of September 7, 2025, skywatchers in parts of the Eastern Hemisphere experienced a total lunar eclipse, where Earth’s shadow enveloped the moon, transforming it into a striking “blood moon.” This celestial event, however, was accompanied by a remarkable sight observed by two weather satellites operated by the National Oceanic and Atmospheric Administration (NOAA): the Geostationary Operational Environmental Satellites (GOES) 18 and 19.

These satellites, part of NOAA’s mission to monitor Earth’s environmental conditions, captured not only the lunar eclipse but also a solar eclipse just hours earlier. Positioned strategically in orbit, GOES-18 and GOES-19 provided a unique perspective of both phenomena, showcasing the intricate dance of celestial bodies.

GOES-18, stationed above regions including the western contiguous United States, Alaska, Hawaii, and parts of Mexico and Central America, recorded detailed images of the sun before the moon obscured its light during the solar eclipse, which occurred from 4:40 a.m. to 5:28 a.m. EDT (0840 to 0928 GMT). Meanwhile, GOES-19, which monitors a wider area including North America, Central and South America, the Caribbean, and the Atlantic Ocean, observed the solar eclipse from 12:34 a.m. to 1:22 a.m. EDT (0434 to 0522 GMT).

As the day progressed, skywatchers eagerly awaited the lunar eclipse, which began at 1:30 p.m. EDT (1730 GMT). This event marked a rare occurrence, as witnessing both a solar and a lunar eclipse in a single day is an extraordinary celestial coincidence.

The images and videos captured by the GOES satellites are not only visually stunning but also highlight the advanced capabilities of modern satellite technology. These satellites play a crucial role in environmental monitoring, providing high-resolution data that informs weather forecasts and climate research.

The dual eclipses serve as a reminder of the universe’s ability to surprise and captivate, offering both professionals and amateur astronomers alike a chance to witness the beauty of our solar system. For those interested in further details, videos of the solar eclipse are available on the CIMSS Satellite Blog, showcasing the remarkable views captured by these satellites.

In a world where technology and nature intersect, the events of September 7 serve as a testament to the wonders of our universe, encouraging ongoing exploration and discovery in astronomy and environmental science.
