Comet Great January Comet of 1910 (C/1910 A1)

Comet Great January Comet of 1910 (C/1910 A1) is currently in the constellation of Aquila, at a distance of 19,166,759,688 kilometers from Earth.

The current Right Ascension of Comet Great January Comet of 1910 (C/1910 A1) is 20h 04m 52s and the Declination is +06° 45’ 48” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom).

The observed values of Magnitude, Coma Diameter and Tail Length are derived from the most recent observation recorded at the Comet Observers Database. The value of Predicted Magnitude comes from the JPL Horizons ephemerides service and, in the case of comets, might be inaccurate given the highly dynamic and unpredictable behavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted 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.
