Keeping track of aurora forecasts, notifications, and community reports.

Did you see the Northern Lights (Aurora Borealis) visibility from last week if you were on that area? If you missed it and want to know more then there are some places where you can get reliable information: 1. Aurora Forecast Websites: Websites like the Space Weather Prediction Center (SWPC), Aurora Service, and the University of Alaska Fairbanks Geophysical Institute provide forecasts and updates on Aurora Borealis activity and visibility in different regions. 2. Mobile Apps: There are several mobile apps available for both iOS and Android devices that offer real-time updates, notifications, and forecasts for the Northern Lights. Examples include My Aurora Forecast & Alerts, Aurora Alerts, and Aurora Watch. 3. Social Media: Platforms like Twitter, Instagram, and Facebook have dedicated Aurora Borealis enthusiast groups, pages, and accounts that share updates, photos, and sightings. Following these accounts can keep you informed about recent Northern Lights activity. 4. Astronomy

Large area solar flares are the likely source of puzzling millimeter emission

Solar flares are sudden explosive processes that convert the energy of the magnetic field into the kinetic energy of electrons and ions. Since the beginning of the century, millimeter observations of solar flares became routinely possible at a few frequencies with limited spatial resolution (see Kaufmann 2012, as a review). One of the most puzzling aspects of the observations at millimeter wavelengths (200-400 GHz) is the presence, in some flares, of a bright spectral component that grows with frequency. This emission is about a hundred trillion times more powerful than the power from the active millimeter full body scanners used in airports around the world.
