• P/1999 V1(Catalina) It has been uneventful these days only faint comets being visible. Will the appearance of a great comet surprise us soon? Observations at Geisei have been continuing in sub-zero temperatures. I have been using an old way of tracking or guiding called the Metcalf method, which was devised in the first half of the 20th century. I have provided observation data here before reporting them to the Smithsonian. I tracked C/1999 A1, which may disappear on January 27, using this Metcalf guiding method with three 30-minute exposures. Romer at Flagstaff usually used 60-120-minute exposures. In the dome I felt like being frozen in ice and was there for as long as 7 hours!
