    Dear colleagues, P/2005 L1 (McNaught) was observed on Feb. 4, 2011 (M.P.E.C. 2011-D06). It is the first positive observation after the aphelion passage.

      Dear colleagues,

      P/2005 L1 (McNaught) was observed on Feb. 4, 2011 (M.P.E.C. 2011-D06).

      It is the first positive observation after the aphelion passage.

      http://www.aerith.net/comet/catalog/2005L1/2013.html

      But, no designation (P/2011 C4 or so) was assigned in this case. No
      recovery announcement in IAUC has been issued yet.

      For example, the recovery of P/2006 U1 (LINEAR) was issued in IAUC
      9194 and the designation P/2011 A4 was assigned.

      Recent observation of P/2005 L1 (McNaught) was not regarded as
      recovery?

      Best regards,

      Dear Seiichi, on images of January, 30 2011 I have no detection of the comet down to 20 mag. Where can I see observations of PK05L010 in 2011? No observations

        Dear Seiichi,



        on images of January, 30 2011 I have no detection of the comet down to 20
        mag.



        Where can I see observations of PK05L010 in 2011?
        No observations in the MPCs or in MPCOBS.

          I could not find the recent observations of P/2005 L1, either.

          Only I found is, the orbital elements of P/2005 L1 are revised in the

              The inclusion of a new orbit for P/2005 L1 was an error. Note
              that no observations of that object were published on D06. There
              was a single-night report of a recovery, but I don't think it
              is correct. I'll replace the orbit on the next "Observations and
              Orbits of Comets" MPEC.
