Bright comets visible this month (July 2017)

One of my responsibilities is being Coordinator of the Comet Section of the Association of Lunar and Planetary Observers (ALPO), an amateur-professional organization that has been conducting observations of solar system objects for the past 70 years.

Every month I post a review of comets that are visible in binoculars and small telescopes. This month’s review includes information on comets C/2015 V2 (Johnson), C/2015 ER61 (PANSTARRS), 29P/Schwassmann-Wachmann 1, 41P/Tuttle-Giacobini-Kresak, 71P/Clark and 217P/LINEAR.

Please check out my ALPO Comet Section post about observing the July’s comets.

Note, that if you do observe any of these or other comets, I am interested in your observations for both this blog and the ALPO. You do not need to be a member of the ALPO to contribute though annual membership in the ALPO is relatively affordable (as low as $14) and includes a subscription to a quarterly journal full of scientific articles on solar system objects.
