115254 Fényi           Discovered 2003 Sept. 22 by K. Sárneczky and B. Sipőcz at Piszkéstető.
Gyula Fényi (1845-1927) was a Hungarian Jesuit and astronomer. A most prolific observer of solar phenomena, his 32-year continuous series of prominence observations with the same instrument is unique. Fényi was the first to demonstrate a correlation between the numbers of solar prominences and sunspots.
