Looking for transient objects? There's an app for that...
The application, called Transient Events, uses real-time observational data from the University of Arizona's Catalina Sky Survey to monitor transient objects, or objects that change in brightness or position.
Users select events that interest them, then images are downloaded from the Skyalert database, housed at Caltech. Next, users receive a reference picture and four subsequent images taken over the course of 40 minutes---images that led to the object's discovery.
"With Transient Events, amateur and professional astronomers can monitor what's happening in the night sky," said Stephen Larson, founder of the Catalina Sky Survey. "If they see something of particular interest, they can point their telescopes at the object to take a closer look."
