The first column gives the definitive International Sunspot Numbers for the whole disk of the sun (RI) established by the Sunspot Index Data Center Brussels on the basis of Locarno as reference station, the second gives the same quantity for the central zone (RIC) on the basis of the observations of Athens (Nat.Obs.); Athens 32404; Uccle; Catania by ussps 31405; Culgoora; Grimbergen; Holloman; Hvezdaren; Izernhagen; Kawaguchi-Saitama; KisIovodsk; Learmouth; Mie-Ken; Mons; Nijmegen; Palea Penteli; Palehua; Ramey;Ronse- Renaix;Roquetes-Tortosa; Smolian; Sobota; Suwa-city; Taipei Obs.;Tilburg;Tokyo-Sc. Museum; Urawa-Saitama. The diameter of the central zone is half that of the solar disk. The Sunspot areas AC are from Catania, AR from Roma and AI are mean quantities calculated by the Sunspot Index Data Center on the basis of observations of Athens (Nat. Obs.), Roma, Lunping, Helwan, Jeddah, Palea Penteli, Taipei Obs. and Taipei Weather Bureau and rattached to Catania by a monthly scaling factor. The apparent total area of the umbra plus penumbra is uncorrected for foreshortening and expressed in millionths of the solar disk. JANUARY 1995 1995 JAN.
