This observation is a confirmation of an apparently asteroidal object reported by the LINEAR survey and posted on the Minor Planet Center's 'NEOCP' webpage .
I have made several observations with R-Bessel filter and with clear filter, but i couldn't find a irrefutable evidence in my observations, made with several telescopes. On this reason i don't send my observation to CBAT.
After more detailled looking, i could see an evidence that this object show cometary appearance.  The images on the left of 19  and 20 december show some cometary appearance.
My astrometric observations with several remote telescopes (Lightbuckets.com (H11) and Tzec-Maun.org (H10)) and mostly observations made with my own backyard observatory (B96) can you find in
