 In 1980, the Einstein Observatory produced a detailed X-ray energy curve of a stellar flare on Proxima Centauri.Further observations of flare activity were made with the EXOSAT and ROSAT satellites, and the X-ray emissions of smaller, solar-like flares were observed by the Japanese ASCA satellite in 1995.Proxima Centauri has since been the subject of study by most X-ray observatories, including XMM-Newton and Chandra.
