Welcome to my Southern Comets website.

Here you will find information, finder charts and images of Comets - past, present and future, plus other observations of interest.

Current Brightness of Present/Future comets from 35S latitude on 2019 May 20

Very quiet period for comet observing!

29P Schwassmann-Wachmann 12th magnitude outbursts
C/2018 N2 ASASSN
12th magnitude and brightening. Low Northeastern morning sky.
May
reach 10th magnitude in November 2019.
 
C/2016 M1 PANSTARRS
13th magnitude and fading. South-western evening  sky.
Peaked at magnitude 8.0 in June 2018.
 
C/2018 A6 Gibbs 13th magnitude and steady. South-western evening  sky.
C/2017 M4 ATLAS
13th magnitude and steady. Overhead at midnight.
 
C/2017 T2 PANSTARRS
13th magnitude and brightening. Very low North-western evening sky.
May reach 6th magnitude in May 2020.
 
C/2018 W2 Africano
15th magnitude and brightening.
May reach 10th magnitude in September 2019
 
C/2018 Y1 Iwamoto
13th magnitude and fading. In Solar Conjunction.
Peaked at magnitude 6.5 in mid February 2019.
 
46P Wirtanen
Peaked at magnitude 3.5-4 in mid December 2018.
 
C/2017 K2 PANSTARRS
D
iscovered on 2017 May 21 at a distance of 16 AU, almost a record for a comet discovery.
Currently at magnitude 16, implies a very large comet (absolute magnitude of 1)
Perihelion occurs in December 2022 at 1.8AU. It will be distant from the Earth and Sun, thus may only reach magnitude 5 and favour observers in the southern hemisphere.

THE DOUBLE COMET SHOW OF MARCH 2013
Was one of the highlights on the comet observing calendar.
2 comets C/2011 L4 PANSTARRS and C/2012 F6 Lemmon
were simultaneously visible to the unaided eye during the evenings of early March 2013

GREAT COMETS
What a privilege it is to observe a great comet. My tally is 4 since I began observing comets in 1986.
Click on links for additional photos and information.

C/1996 B2 Hyakutake (Great comet of 1996)
C/1995 O1 Hale-Bopp (Great comet of 1997)
C/2006 P1 McNaught
(Great comet of 2007)
C/2011 W3 Lovejoy (Great comet of 2011)

Weekly comet information by Seiichi Yoshida http://www.aerith.net/comet/weekly/current.html
In my opinion the best website for comet information and light curve predictions.
