Briefings

A complete auroral oval was captured by SMILE spacecraft in late July 2026, visible in ultraviolet light during the day. The time-lapse shows turbulent auroras spanning an hour, with light points on the sides being distant stars due to the spacecraft's orbital view shift. This observation helps understand how the Sun's wind interacts with Earth's magnetosphere, aiding in astronaut and grid protection.

Key points

• SMILE spacecraft captured a complete auroral oval visible in ultraviolet light during the day in late July 2026.
• The time-lapse covers approximately one hour and demonstrates the variable and turbulent nature of auroras.

Context

SMILE (Solar and Magnetospheric Ionization Laboratory Explorer) is a robotic spacecraft operated by ESA and CAS. Its primary goal is to study how the Sun's wind interacts with Earth's magnetosphere to protect astronauts, spacecraft, and electrical grids from solar storms.

Limitations

Evidence is limited to a single time-lapse image from late July 2026. The specific date of the full oval's formation is not confirmed, and the exact spatial extent of the oval is not fully quantified in the provided text.
