2025-26 apparition ‒ current lightcurve:

Format:
Date, RA, Dec, Magnitude, Observatory Code, Photometric aperture in arcsec, Comments

The number to the right of the IAU observatory code is the measuring aperture size in arcsec (value in brackets is the effective size since Astrometrica adds 0.5 pixel to the radius size).

Observer information is at the foot of the list.

29P’s Final lightcurve for the 2022‒2023 apparition

The 2022-23 apparition has now ended and the plot below has been updated as of 2023 Jul 18. This apparition we have had 20 mini-outbursts during the 11 months’ coverage, the first was detected by Jean-François Soulier on 2022 Jul 26, the last by Soulier and Eric Watkins on 2023 May 26. The individual photometric observation lines for this apparition (2022 – 2023) have been archived here and on the main News page.

Each of the 962 datapoints in the plot is an average for a particular epoch (time-series) and observer.
