When Does Comet P/2016 J3 (STEREO = 2021 A3) Rise and Set?
Today's Comet P/2016 J3 (STEREO = 2021 A3) rise, transit and set times from Greenwich, United Kingdom are the following (all times relative to the local timezone Europe/London):
The rise and set times are defined as the time at which the upper limb of Comet P/2016 J3 (STEREO = 2021 A3) touches the horizon, taking into account the effect of the atmospheric refraction. Since the atmosphere conditions cannot be modeled precisely, the times reported here should be considered correct with an approximation of a few minutes.
