Earlier this week, Slooh member Bernd Lütkenhöner and Slooh astronomer Paul Cox were able to image the newly discovered Comet C/2016 R3 (Borisov) under extraordinary conditions. The comet had been close to the Sun since its discovery on September 11th, 2016 by Gennady Borisov, making it extremely difficult to observe.
It had already fallen out of reach of other telescopes around the world by September 16th, but Lütkenhöner and Cox managed to image it on September 20th using Slooh’s robotic Half Metre telescope at their flagship observatory at the Institute of Astrophysics of the Canary Islands.
Cox said, “We usually observe objects when they’re high in the sky, so we’re peering through as little of our atmosphere as possible. But in this case, the comet was only observable in the last 30-minutes before dawn, when it was only 5° above the horizon in a rapidly brightening sky. Given the factors stacked against us, we were amazed when we managed to pinpoint the faint and diffuse fuzz ball in our images!”
“We may have obtained the last observations of this comet for the next 100 or even 100,000 years,” said Lütkenhöner. The reason for that huge timespan is that the orbit of this comet hasn’t been fixed with any certainty. Added Cox, “Our latest observations will help determine the orbit of the comet with greater certainty.”
The comet is set to make its closest approach to the Sun (perihelion) on October 12, 2016. Says Cox, “We don’t even know if the comet will survive its journey around the Sun, but if it does, it will remain an extremely difficult object to image because of its proximity to the Sun from Earth’s perspective – but we’ll still give it a try!”
Astronomers require further observations of the comet to confirm whether this is a new discovery or a recovery of a comet discovered in 1915, Comet C/1915 R1 (Mellish).
Slooh members control the robotic telescopes at Slooh’s Canary Islands and Chile observatories every night. Together, they’ve taken more than 5-million images of well over 50,000 objects since Slooh launched in 2003.

About Slooh
Slooh connects humanity through communal exploration of the universe. We gather people around live telescopes to see space for themselves and share their diverse perspectives. Since 2003, Slooh’s automated observatories have processed celestial images in real-time for broadcast to the Internet. Slooh members have taken over 4-million photos/500,000 FITS images of over 50,000 celestial objects, participated in numerous discoveries with leading astronomical institutions and made over 3,000 submissions to the Minor Planet Center. Slooh’s flagship observatories are situated on Mt. Teide, in partnership with the Institute of Astrophysics of the Canary Islands (IAC), and in Chile, in partnership with the Catholic University. Slooh has also broadcast live celestial events from partner observatories in Arizona, Japan, Hawaii, Cypress, Dubai, South Africa, Australia, New Zealand, Norway and many more. Slooh’s free live broadcasts of potentially hazardous asteroids (PHAs), comets, transits, eclipses, solar activity etc. feature narration by astronomy experts Paul Cox and Bob Berman and are syndicated to media outlets worldwide. Slooh signed a Space Act Agreement with NASA in March 2014 to “Bring the Universe to Everyone and Help Protect Earth, Too.”
