C/2015 F3 (SWAN)
Discovered byRob Matson, Vladimir Bezugly and Michael Mattiazzo
Discovery dateMarch 2015

Comet C/2015 F3 (SWAN) was discovered in March 2015 by Rob Matson, Vladimir Bezugly and Michael Mattiazzo in near real time images taken by the SWAN instrument aboard the SOHO spacecraft.[1] At discovery the comet was already shining at around 10th magnitude as it was already near perihelion[2]

. Orbital studies revealed C/2015 F3 to be a related fragment to long periodic comets C/1988 A1 (Liller), C/1996 Q1 (Tabur) and C/2019 Y1 (ATLAS), which were already thought to have broken off each other at a previous perihelion passage. As of May 2015, Comet SWAN was fading rapidly, as both C/1988 A1 and C/1996 Q1 ultimately did.[3][4]
