   Not an aurora???

   Many throughout the world were able to experience another great evening of auroras on New Year’s Day 2025. However, there’s a catch, some actually saw what are known as SAR arcs. These were first discovered in 1956. Researchers weren’t sure what they were and gave them the misleading name, Stable Auroral Red arcs.
