James Dunlop probably discovered NGC 6115 = D 379 = h3625 on 26 Jun 1826. He noted "a small faint round nebula, with a bright centre" and his position is just 5' northeast the cluster. John Herschel independently discovered NGC 6115 on 8 Jul 1834 and recorded "A part of the milky way, so immensely rich as to be one vast cluster of clusters." His single position matches Ru 118. Sky Catalogue 2000.0 labels the cluster as Ru 118 and RNGC misclassifies the NGC 6115 as nonexistent (Type 7).

400/500mm - 18" (4/5/16 - Coonabarabran, 236x): ~30 stars resolved in a small 3' cluster. The brightest mag 10.8 star is at the west edge and includes a number of mag 11.5-13 stars, mostly on the east side. This cluster is unimpressive, though, as it sits in a glorious rich Norma star field that overwhelms the cluster! Ruprecht 116, a scattered group of bright stars (brightest is mag 8.6 SAO 243732), lies 10' WSW.
