NASA Moon Base Ambition Meets Solar Wind Surge
NASA advances lunar infrastructure as a 725 km/s solar wind stream hits Earth and the Leonids meteor shower reaches its peak activity.

Daily Statistics Brief
On 2026-11-10, conditions across the near-Earth environment remained remarkably quiet. The planetary K-index peaked at a modest 2.7 during the early hours, failing to breach the threshold for meaningful geomagnetic storms. By the time of the latest observation, the index had settled to 0. Despite a swift solar wind speed of 683 km/s, the interplanetary magnetic field component, Bz, measured a gentle 2.2 nT, offering little turbulence to drive significant atmospheric interaction.
Reflecting this stability, the aurora hemispheric power dropped to 0 GW. Satellite sensors confirmed the absence of any structural excitation, and the Dst index hovered at -21 nT. The Sun remained equally subdued; observers recorded only a minor B-class flare, a continuation of the quiet cycle observed in recent imagery.
Tracking data from NASA CNEOS confirmed that the nearest asteroids posed no threat to the planet, with 2019 XF2 passing at a safe distance. Meanwhile, the glossary of November night-sky events centred on the approaching Leonids. While the shower remained active between 06/11 and 30/11, the peak was not due until 18/11. Enthusiasts braced for a modest zenithal hourly rate of 15 meteors per hour, with the radiant situated in Leo—a debris trail shed by the parent body 55P/Tempel-Tuttle.
For those monitoring the local forecast for visual phenomena or potential UAP sightings, the day offered a blank canvas. This lack of geomagnetic activity contrasted sharply with the volatility catalogued in our archive. Researchers relying on NOAA SWPC data would have found little to analyse beyond a standard, uneventful rotation of the solar disc. The atmosphere stayed calm, and the magnetosphere remained undisturbed, providing a rare day of total silence in the records of 2026.
