While low-latitude auroras ty pically glow red from oxygen emission, the night showcased a rare salmon- pink aurora and an extraordinary, tall blue-dominant aurora near midnight. The Role of Citizen Scientists in Documenting the Aurora Scientists leveraged amateur  photogra phs and smart phone recordings, combining  public contributions with their research to study the  phenomenon com prehensively. Methodology and Key Findings In their latest research, scientists examined visual data of the blue-dominant aurora to calculate its area, validating these calculations with s pectro photometric measurements. The study ,  published in Earth, Planets and Space , was conducted under the leadershi p of Sota Nanjo, a  postdoctoral researcher at the ...
