On the night of October 22, Unistellar Citizen Scientists will have the chance to participate in our Network’s first transatlantic (or intercontinental) asteroid occultation!
Main-belt asteroid Loreley will pass in front of a distant star from our view here on Earth, an event known as an occultation. Starting at 10:37 PM UTC, it will be visible in a path across Northern Europe from St. Petersburg, Russia to Swansea, Wales, covering almost all of Estonia, Denmark, central England and Wales.
Across the Atlantic Ocean, the occultation will also be visible from Saguenay, Quebec to Lubbock, Texas in North America, starting at 11:20 PM EDT (10:20 PM CDT). The path also goes through Ottawa, Michigan, Illinois, Missouri, and Oklahoma.
Quick Facts about Loreley
- Located in the asteroid belt, roughly between Mars and Jupiter
- Discovered in 1876 by German–American astronomer Christian Heinrich Friedrich Peters
- Named for the Lorelei, a siren from German folklore
- About 112 miles (180 kilometers) across
The Unistellar Network has already made successful detections of Loreley! In July 2020, Unistellar Citizen Astronomer Kevin Voeller detected Loreley from the USA. Earlier this month, Joachim Siegert and Benjamin Mirwald from Germany, as well as Josef Hanus from Czechia, all Citizen Astronomers from the Network, also detected Loreley.
