Hallo,

in Vertretung von Uwe die Info, das Erwin Schwab wieder einen Kometen wiederentdeckt hat.

Info dazu https://www.minorplanetcenter.net/mpec/K18/K18R59.html

Eine Animation ist bereits in unserer Bildergalerie enthalten.

Gruß,
Stefan

Das hätte ich einen Tag früher wissen müssen, dann hätte ich ihn heute früh gleich aufs Korn genommen. Habe den Kometen schon 2001 vergeblich versucht, dieses Mal müsste es aber klappen.

Gruß
Werner

überraschend schwierig, den Kometen auf die Platte zu bannen, aber im zweiten Anlauf mit längerer Belichtung hats geklappt (Astrometrica sagt 19m7), 18x 3min, 16" f/2.5

Hier noch die vollständige CBET- Meldung:
Code:
COMET P/2018 R1 = P/2001 R6 (LINEAR-SKIFF)
    E. Schwab, Egelsbach, Germany, reports the recovery of comet P/2001 R6
(cf. IAUC 7723) on CCD images obtained by D. Abreu with a 1.0-m f/4.4
reflector at the European Space Agency's Optical Ground Station, Tenerife
(astrometry tabulated below).  The comet shows no coma and no tail on stacked
images with 600 s total exposure time.  Assisting in the measurements were
M. Micheli, D. Koschny, A. Knoefel, and M. Busch.

    2018 UT             R.A. (2000) Decl.       Mag.   Observer
    Sept. 7.08501    2 08 16.55   -13 25 56.0   19.8   Abreu
          7.14283    2 08 16.67   -13 26 02.4   19.8     "
          7.20030    2 08 16.83   -13 26 08.6   19.9     "
          8.11194    2 08 20.48   -13 27 49.1   19.1     "
          8.21684    2 08 20.60   -13 28 00.4   20.0     "

The indicated correction to the prediction by G. V. Williams on MPEC 2013-A29
is Delta(T) = +0.36 day.  The following linked orbital elements (including
elements at the missed 2010 return to perihelion) by Williams from 95
observations spanning 2001 Aug. 19-2018 Sept. 8 (mean residual 0".6) and an
ephemeris appear on MPEC 2018-R59.

                   Epoch = 2010 Mar. 25.0 TT
    T = 2010 Mar. 26.34015 TT        Peri. = 308.45182
    e = 0.4776943                    Node  =  67.32340 2000.0
    q = 2.1786419 AU                 Incl. =  17.38669
      a =  4.1712010 AU   n = 0.11569441   P =   8.52 years

    e = 0.4759541                    Node  =  67.33485 2000.0
    q = 2.1910673 AU                 Incl. =  17.37964
      a =  4.1810600 AU   n = 0.11528544   P =   8.55 years
