How much of the world came to miss the greatest comet in decades (and what communicating astronomy with the public may have had to do with it) Daniel Fischer FG Kometen der VdS Germany CAP 2007 AthensSlide2: Early August 2006 An inconspicious beginning ... ● A most promising orbit for January 2007 ... ● ... but close to the Sun all the time ... ● ... and predicting comet brightnesses is an artSlide4: The first days of January 2007: early hopes and worries (on specialist sites) January 1: author says -6 ... mSlide5: January 7 Astronomy buffs in mass media take noticeSlide6: January 9Slide7: January 9: the first press release (from ‚someone‘) I‘ve seen!Slide8: Visual impression equal to typical digital photograph!Slide9: January 10Slide14: January 11Slide16: January 12 Phase 2: daytime views! End of phase 1: North, bright, small in size, lowSlide17: January 13Slide18: A risky conundrum: exceedingly rare event, but only with very clear skies and possibly dangerous! -> hardly mentioned at allSlide19: January 14: perihelion! -5.5 mag.! Daylight naked eye in places! January 15: Southern window about to open – now what ...?Slide20: January 18: ½ week of greatest glory!

C/2007 N3 (Lulin) – February 17 til 28, 2009 Brightness about +5.0 mag. -> faint naked eye, easy binocular, nice small telescope view In opposition to the Sun (elongation 170-180°) No Moon in the sky – visible in 1st half of night Elevation 35 ... 45° for Central Europe 70 ... 80° for Mexico 40 ... 50° for Australia A comet for the whole planet to enjoy!
