Partial Solar Eclipse & Plane Transits

Captured from the UK on the evening of August 12, 2026, this observation documents the dramatic solar eclipse as seen from British skies. While the narrow path of totality tracked across Greenland, Iceland, and northern Spain, observers across the United Kingdom were treated to a deep, high-magnitude partial eclipse, with the Moon carving away over 90% of the Sun's radiant disc.

During the observation run, two separate commercial aircraft crossed directly through the line of sight between the telescope and the Sun. The first captured a striking, razor-sharp silhouette of an airplane frozen in flight against the glowing solar crescent and nearby sunspot groups. The second captured a high-speed transit with its heat exhaust and contrail streak slicing across the upper solar limb. The accompanying timelapse video preserves the entire cosmic alignment in motion.

Fun Facts

  • The eclipse of August 12, 2026 was the first total solar eclipse visible from continental Europe since 1999, casting a deep partial shadow across the UK with over 90% obscuration near the western horizon
  • Two airplane transits captured - the airliner was cruising at roughly 35,000 feet and over 500 mph, traversing the entire solar disc in just a fraction of a second
  • In the first transit photo, subtle dark freckles are visible on the Sun's surface: sunspots, regions of concentrated magnetic field that are each significantly larger than our entire planet
  • Specialised solar filters are essential for imaging the Sun, cutting out 99.999% of incoming solar energy to protect sensitive imaging sensors from being destroyed
  • The Moon and Sun appear almost the exact same size from Earth purely by celestial coincidence: the Sun is 400 times wider than the Moon, but situated 400 times further away

Processing Notes

Captured on a fantastic evening near the disused Harrington Airbase, overlooking a low band of trees which you can see at the end of the timelapse as the sun set.
