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

Innovation increases observable volume of the universe by a factor of seven

The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600, LIGO, Virgo) are so sensitive that they are fundamentally limited by tiny quantum mechanical effects. These cause a background noise which overlaps with gravitational-wave signals. This noise is always present and can never be entirely removed. But one can change its properties – with a process called squeezing, to date only used routinely at GEO600 – such that it interferes less with the measurement. Now, GEO600 researchers have achieved better squeezing than ever. This opens new ways to improve the international detector network in the next observation runs and is a key step to third-generation detectors such as the Einstein Telescope.
