NASA’s Solar Observatory Sees Two Eclipses in One Day

NASA’s Solar Dynamics Observatory (SDO) has witnessed and recorded an unprecedented phenomenon of two photo voltaic eclipses in at some point on July 25, 2025. These two eclipses happened solely hours aside that day, and had been photographed by SDO devices pointed up and away from the Sun in geosynchronous orbit. First, round 2:45 UTC, the Moon handed between SDO and the Sun. Then, beginning at about 6:30 UTC, Earth itself eclipsed the Sun from SDO’s perspective, with the Sun disappearing behind our planet shortly earlier than 8:00 UTC. Since launching in 2010, SDO has constantly monitored the Sun’s exercise, from photo voltaic flares to magnetic fields, serving to forecasters predict house climate.

Moon Transit

According to NASA, SDO orbits Earth in a excessive geosynchronous orbit, so it has an virtually fixed view of the Sun. On July 25, this vantage level captured a partial photo voltaic eclipse because the Moon handed between the spacecraft and the Sun. NASA’s mission staff had predicted this “lunar transit” would cowl about 62% of the photo voltaic disk. Indeed, the Moon’s silhouette moved slowly throughout the Sun (round 2:45–3:35 UTC), blocking roughly two-thirds of the brilliant disk at most. The observatory’s ultraviolet telescope (AIA) recorded the occasion, revealing the Sun’s decrease environment and coronal loops across the sharply outlined lunar edge. This transit was the deepest lunar eclipse SDO noticed in 2025.

Earth’s Eclipse from Space

Hours later, on the identical day, Earth itself handed between SDO and the Sun. Beginning round 6:30 UTC on July 25, our planet absolutely blocked the observatory’s view of the photo voltaic disk. This occurred throughout SDO’s common eclipse season (a roughly three-week interval twice annually when Earth’s orbit crosses the satellite tv for pc’s line of sight). The whole eclipse lasted till shortly earlier than 8:00 UTC. In SDO’s photographs, Earth’s shadow has a fuzzy edge as a result of our environment scatters daylight, in distinction to the Moon’s crisp eclipse.
