Comet Ikeya-Seki (C/1965 S1)

Comet Ikeya-Seki (C/1965 S1) is currently in the constellation of Canis Majoris. The current Right Ascension of Comet Ikeya-Seki (C/1965 S1) is 06h 45m 13s and the Declination is -11° 35’ 18” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt).

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.
