Notable dates in 2018
Note that several D/ (destroyed or disappeared) comets that are included below are predicted to return to perihelion, though searches at favourable returns in the intervening period have failed to reveal them and the orbits will have been perturbed by Jupiter. 2018 Jan 1 Mercury western elongation Jan 2 Full Moon Jan 3 Jacques (2017 K6) at opposition, magnitude 15 Jan 7 Mars 0.2d south of Jupiter Jan 8 ATLAS (2017 K4) at opposition, magnitude 17 Jan 17 New Moon Jan 21 130P/McNaught-Hughes at opposition, magnitude 17 Jan 26 74P/Smirnova-Chernykh at opposition, magnitude 15 Jan 27 185P/Petriew at opposition, magnitude 11 Jan 28 197P/LINEAR at opposition, magnitude 18 Jan 31 Full Moon Feb  1 250P/Larson at opposition, magnitude 18 Feb  4 D/Denning (1894 F1) at opposition Feb 15 New Moon Feb 19 PANSTARRS (2015 O1) at opposition, magnitude 15 Feb 21 Heinze (2017 T1) at opposition, magnitude 10 Feb 23 3D/Biela at opposition Feb 26 Catalina (2017 S6) at opposition, magnitude 16 Mar 2 Full Moon Mar 15 Mercury eastern elongation Mar 17 235P/LINEAR at opposition, magnitude 18 Mar 17 New Moon Mar 31 Full Moon Apr 16 New Moon Apr 22 Lyrid meteor shower Apr 29 169P/NEAT at opposition, magnitude 16 Apr 30 Full Moon May 4 37P/Forbes at opposition, magnitude 12 May 7 143P/Kowal-Mrkos at opposition, magnitude 17 May 9 PanSTARRS (2016 R2) at opposition, magnitude 9 May 9 Jupiter at opposition May 9 388945 passes 6.5 LD May 12 2016 HP6 passes 2.3 LD May 15 New Moon May 16 240P/NEAT at opposition, magnitude 18 May 19 66P/du Toit at opposition, magnitude 13 May 22 159P/LONEOS at opposition, magnitude 18 May 23 107P/Wilson-Harrington at opposition, magnitude 16 May 26 187P/LINEAR at opposition, magnitude 17 May 29 68347 passes 9.5 LD May 29 Full Moon May 31 164P/Christensen at opposition, magnitude 15 Jun 11 2015 DP155 passes 9.0 LD Jun 13 New Moon Jun 14 64P/Swift-Gehrels at opposition, magnitude 13 Jun 22 P/Catalina (2011 CR42) at opposition, magnitude 16 Jun 24 P/PANSTARRS (2013 CU129) at opposition, magnitude 11 Jun 25 TOTAS (2017 M5) at opposition, magnitude 18 Jun 28 Full Moon Jun 28 Saturn at opposition Jun 28 D/Swift (1895 Q1) at opposition Jun 28 82P/Gehrels at opposition, magnitude 18 Jul 2 361P/Spacewatch at opposition, magnitude 18 Jul 12 Pluto opposition Jul 12 Mercury eastern elongation Jul 13 New Moon Jul 15 49P/Arend-Rigaux at opposition, magnitude 13 Jul 18 PanSTARRS (2016 N6) at opposition, magnitude 14 Jul 27 Full Moon Jul 27 Mars at opposition Jul 27 Total lunar eclipse Aug 10 PanSTARRS (2016 M1) at opposition, magnitude 9 Aug 10 105P/Singer Brewster at opposition, magnitude 18 Aug 11 New Moon Aug 12 48P/Johnson at opposition, magnitude 10 Aug 13 Perseid meteor shower Aug 16 PanSTARRS (2017 S3) at opposition, magnitude 4 Aug 17 Venus eastern elongation Aug 26 Mercury western elongation Aug 26 Full Moon Aug 26 243P/NEAT at opposition, magnitude 17 Sep 7 Neptune at opposition Sep 9 New Moon Sep 10 21P/Giacobini-Zinner at opposition, magnitude 4 Sep 13 79P/du Toit-Hartley at opposition, magnitude 16 Sep 16 59P/Kearns-Kwee at opposition, magnitude 16 Sep 20 133P/Elst-Pizarro at opposition, magnitude 17 Sep 25 Full Moon Oct 1 26P/Grigg-Skjellerup at opposition, magnitude 15 Oct 3 3D/Biela-A at opposition Oct 4 P/LINEAR-Skiff (2001 R6) at opposition, magnitude 17 Oct 9 New Moon Oct 11 D/Brooks (1886 K1) at opposition Oct 24 Full Moon Oct 24 Uranus at opposition Oct 29 475534 passes 7.5 LD Nov 2 300P/Catalina at opposition, magnitude 17 Nov 7 New Moon Nov 11 38P/Stephan-Oterma at opposition, magnitude 9 Nov 17 Leonids meteor shower Nov 23 Full Moon Dec 2 247P/LINEAR at opposition, magnitude 18 Dec 6 P/Catalina-PANSTARRS (2013 R3) at opposition, magnitude 18 Dec 7 New Moon Dec 11 60P/Tsuchinshan at opposition, magnitude 14 Dec 13 46P/Wirtanen at opposition, magnitude 3 Dec 13 137P/Shoemaker-Levy at opposition, magnitude 18 Dec 13 198P/ODAS at opposition, magnitude 15 Dec 14 Geminids meteor shower Dec 22 163899 passes 7.4 LD Dec 22 Full Moon
