(15903) Rolandflorrie Main-belt Asteroid
Discovered on 5 September 1997 by T. Handley at Burlington.
Roland (1914-1999) and Florrie (1912-2000) Handley were the parents of the discoverer, an amateur astronomer who suffered from Asperger's Syndrome. Their love and encouragement greatly helped in his endeavor to measure precise positions of comets and asteroids.Naming citation (MPC batch dated 2016-02-22), IAU / Minor Planet Center, via NASA/JPL
