Comet P/2012 NJ (La Sagra)
- Hi to all comet/asteroid friends
As announced on CBET 3178, we found that the NEA 2012 NJ
shows a distinct narrow tail. Here we want to share the images.
At the following link
you can find stacked images, which are taken in the R Band filter,
during the nights July 17 - 19 from the Calar Alto Observatory.
These images where taken in course of our photometric
observing programme, and the primary aim of the campaigns
is to get lightcurve data to determine rotational properties of
asteroids and comets.
For 2012 NJ we have now photometry (R) during four nights,
and can see a preliminary rotation period of about 13 hours, but
no unique solution yet. We therefore ask other observers, who
might have photometric data as well to get in touch with us, so
we could join forces and obtain a better coverage of the rotation
cycle. Our campaign will cover one additional night.
Looking forward to hear from you.
PS.: Congratulations to the La Sagra team for yet another outstanding
discovery! Via Espana!
