This report describes and analyses the observations of the brighter or more interesting comets discovered or at perihelion during 2013, concentrating on those with visual observations. Magnitude parameters are given for all comets with observations. Any evolution in the magnitude parameters of those periodic comets with multiple returns is discussed. Additional information on the comets discussed here and on other comets seen or at perihelion during the year may be found on the Comet Section’s visual observations web pages.
