Visual observations of comets

Each visual observation record consists of: the name of an object observed, UT date and time (in hundreds of day), the name of a method used for visual magnitude estimate, the estimate itself, reference for magnitude estimates, aperture (in centimeters) of the telescope, type of instrument and its focal ratio and magnification, estimated diameter of the coma (in arc minutes), degree of condensation, estimated length of the tail and position angle (both in degrees),limiting magnitude, observing site, full estimation degrees, designations and brightnesss of comparison stars and a short description of comet appearance.
