Comet C/2017 O1, discovered by the ASASSN supernova survey, as seen from the SSO scopes at astronomical twilight. The rectangle is the field of view of T12.

Comet C/2017 is a surprisingly bright comet which was recently discovered by the ASASSN supernova survey. It is currently around magnitude 9.8. It is unclear if the comet is in outburst, or has "switched on" as it crossed the frost line.

While the comet is already bright, observations are requested to follow its development. It is predicted to reach magnitude 7.5 in October.

Currently it is between Cetus and Eridanus, above Eta Eri. It is currently best seen in the SSO scopes, from about 230 am local time to astronomical twilight, from the Northern scopes the observations are limited to just before astronomical twilight. Currently it has no ineteresting encounters.

Over the month the comet evolves into a better viewing position, but by September it is more favourable for the northern scopes, and at maximum it is a northern object.
