Comet 77P/Longmore Rise and Set Times - Today
Today's Comet 77P/Longmore rise, transit and set times from Greenwich, UK are the following (all times relative to the local timezone Europe/London):
RISE
Azimuth: 94.7°
TRANSIT
Max altitude: 33.8°
SET
Azimuth: 265.3°
The rise and set times are defined as the time at which the upper limb of Comet 77P/Longmore 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.
