Jon Larsen (b. 1959) is a Norwegian gypsy jazz guitarist and amateur science researcher. In the spring of 2009, spotting a tiny black speck landing on his newly laid white table cloth on a balcony table, his curiosity led him to a six-year journey to discover micrometeorites in cities full of contamination.Naming citation (WGSBN Bull. 5, #1, 19), IAU / Minor Planet Center, via NASA/JPL
