R: [comets-ml] Re: A Potential Comet waiting to confirm!
- Hi Juan,
for me the comet is normal.
I think that your stack is affected by an error in PA due to the first
ephemerides posted on the NEOCP.
If you try to restack your images with the motion vector that is *now* in te
NEOCP, all should go well.

- Dear Maik:
Last night there are really many mistakes in our reports,
However, I have measured our images right now using astrometry
Below are observations, it seems the brightness is all right now,
But I'm not really sure about the m1 and m2, especially the m1 when
comets became diffuse.
