            Tail 25' long; LM 6.3 (comet seen with the naked eye
            some hours before under better LM)
20.05  M    m1=5.7 Dia.=19' DC=3   7x50B  Jure Atanackov, MB, Slovenia
            Tail 45' long; LM 6.6 (comet easily seen with the naked eye around

21.95  M    m1=6.7 Dia.=13' DC=5   7x50B  Jure Zakrajsek, Jez. vrh, Slovenia
            Comet seen with naked eye under LM 7.0; tail 40' in PA 230 deg.
21.96  M    m1=7.1 Dia.=14' DC=4   7x50B  Jure Atanackov, Jez. vrh, Slovenia
            Tail 45'; comet seen with naked eye under LM 7.3,

            LM 6.7; tail 30' long
28.05  M    m1=6.9 Dia.=7' DC=4    7x50B  Jure Zakrajsek, Graska gora, Slovenia
            No tail was seen. Comet was difficult to estimate because of
            a star near it's coma. Comet is much smaller than few days back
            but still an easy object for 750B!
29.06  M    m1=6.8 Dia.=8' DC=4    7x50B  Jure Zakrajsek, Graska gora, Slovenia
            No tail was seen. LM 6.5, high humidity.
