The Lumara log
Short entries, written when something is actually happening: a flare worth looking at, a storm that might put aurora somewhere it does not usually go, an eclipse, a meteor peak, a moon worth stepping outside for. Everything here is checked against NASA and NOAA data before it goes up.

August 12, 2026: a total eclipse and the best Perseid night of the decade
Two events most years would be lucky to get separately land on the same date. Here is what happens when, where each one is visible, and why the Perseids will not look this good again until 2028.
