iPTF 14atg is a type-Ia supernova discovered on 3 May 2015. The supernova is located in galaxy IC 831, some distant.〔 〕 The supernova is thought to have ignited on May 2nd or 3rd.〔 〕 The supernova's shockwave slammed into a companion star, shocking it into producing an ultraviolet pulse.〔 〕 The companion star that was hit is suspected to be a red giant star.〔 〕 This detection of the UV signal represents the first time the collision event of a supernova shockwave upon a companion star has been detected.〔 〕 The supernova was discovered by the Intermediate Palomar Transient Factory (iPTF), a successor to the earlier Palomar Transient Factory, and based at the Palomar Observatory in California. The data was processed by collaborators in Europe, that lead to the supernova discovery.〔
