(meteorobs) Hartley-ids in the coming nights?

[Rainer Arlt]

Hi Joe and all,

Additionally, here is the output of Neslusan's programme to compute 
the possible radiant by various methods from the comet's orbit:

 Meth    RA      Dec    Vg      Vh      Sollon   Date        D-crit
-------------------------------------------------------------------
  -Q    298.1   29.8   12.05   38.93    219.8   NOV.  2.5    0.067
  -B    298.1   29.8   12.05   38.93    219.8   NOV.  2.5    0.067
  -P    296.8   33.4   11.07   37.69    219.5   NOV.  2.2    0.125

I don't remember which symbol refers to which method, but
the results are all quite similar anyway. Note that the 
apparent radiant will be shifted towards the zenith 
considerable (up to about 10 degress) by zenithal 
attraction due to the low geocentric velocity.

Best regards,
Rainer
