When Does James Webb Space Telescope Rise and Set?
Today's James Webb Space Telescope 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 James Webb Space Telescope 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.
