At the time of writing this reports from Tony Angel (Spain) and John McConnell (Northern Ireland) accompanied by images suggest further activity and perhaps brightening. The latter report from John shows the comet easily recorded on Jan 7 with a mere 50mm f1.8 lens! This comet is well worth monitoring. Ephemeris: Date TT R. A. (2000) Decl.
