Philophrosyne (/fɪləˈfrɒsəniː/ or /fɪləˈfrɒzəniː/), also Jupiter LVIII and provisionally known as S/2003 J 15, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al. in 2003,[2][3] but then lost.[4][5][6][7] It was recovered in 2017 and given its permanent designation that year.[8]

We likely have all of the lost moons in our new observations from 2017, but to link them back to the remaining lost 2003 objects requires more observations a year later to confirm the linkages, which will not happen until early 2018. ... There are likely a few more new moons as well in our 2017 observations, but we need to reobserve them in 2018 to determine which of the discoveries are new and which are lost 2003 moons.
