For each of the listed comets, the current position is plotted in the below all-sky chart:





    Terminology:
            
    delta:      Distance between comet and earth in AU
    radius:     Distance between comet and sun in AU
    magn:       Magnitude (brightness) estimate    
    elong:      Elongation in degrees (angle sun-earth-comet)    
    AU:         Astronomical Unit (mean distance between earth and sun: 149597870.7 km
    Perihelion: On this date the comet (or other type of body) is closest to the sun
    Hₒ:         Absolute magnitude (magnitude from a distance of 1 AU)
