About 1300 years ago, an unexplained cosmic storm hit our planet. It left its imprints in the tree rings across the globe and the ice cores of Antarctica. Then, after 200 years, the event repeated, but this time it was 60% as strong. 1/

Photobombed by Luna 🌚 A partial solar eclipse was recorded from space by the Solar Dynamics Observatory, in a geosynchronous orbit around Earth 🛰 The moon swept past the solar disc from NW to SE, and also note the minor flare (C6.9) from AR 13312 (SE limb) after the passage! ☀️
New Research: Primary and albedo protons detected by the Lunar Lander Neutron and Dosimetry experiment on the lunar farside https://t.co/19NHTjISLp #SpaceSci
The second scientific paper from @zigong_xu used the data from LND. This time we focused on the gcr protons and the albedo protons on the lunar surface.
The large AR 12887 did not let us down, as it released an X1.0 flare with related coronal mass ejection (CME) just as it was crossing the central meridian of the Earth-facing Sun. Expect increased solar energetic particle (SEP) fluxes and a CME that might be coming our way ☀️💥
Hello, world! My name is Lunar Lander Neutron and Dosimetry, short name LND. I am here. I will tell you what happens on the lunar far side and tell the astronaut how much radiation dose and how the radiation change on the von Kármán crater.
