Comet C/1956 R1 (Arend-Roland) brightness
The current visual magnitude of Comet C/1956 R1 (Arend-Roland) is -100.00.
The observed magnitude and coma diameter values are derived from the Comet Observers Database by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude comes from the JPL Horizons ephemerides service and might be inaccurate given the highly dynamic and unpredictable behavior of comets. When available, please refer to the Observed Magnitude value and consider the Estimated Magnitude as a directional indication. We acknowledge with thanks the comet observations from the COBS Comet Observation Database contributed by observers worldwide and used in this table to report recent comet observations.
Comet C/1956 R1 (Arend-Roland) rise and set times
Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London
Comet C/1956 R1 (Arend-Roland) is circumpolar and transits at 19:31 UTC (altitude: 72.2°)
The rise and set times are defined as the time at which the upper limb of Comet C/1956 R1 (Arend-Roland) touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
