CONFIRMATIONS ON C/2006 M2 (SPACEWATCH)

  On June 20.66, 2006, C. S. Lin and Q. Ye observed an NEOCP object SW40XA, which latter proved to be a new comet, which was discovered by R. S. McMillan of Spacewatch Project, U.S.A. The discovery was annouced in IAUC 8725 and the observations were published in MPEC 2006-M27. Here are the observations of Lulin Sky Survey:
    CK06M020  C2006 06 20.65718 16 02 05.22 +02 11 15.4          20.9 N EM027D35
    CK06M020  C2006 06 20.66800 16 02 04.62 +02 11 13.7          19.7 N EM027D35
  We did not reconized any cometary appearance of the object. The object is faint, star-like, a little bit diffuse on our image. The image of C/2006 M2, taken by C. S. Lin and proceed by Q. Ye, can be view here: http://csc.lamost.org/yeiht/wordpress/index.php?page_id=140&file=Lulin%20Sky%20Survey/sw40xas001r0011.PNG.
  On June 22, J. Young and R. S. McMillan respectively used Table Moutain's 0.6-m f/16 and Kitt Peak's 1.8m f/2.7 telescope, confirmed that the object has a 4"-6" coma. The object is now 4.6 AU away from the Earth, it has passed the perihelion on late 2005 at about 5.2 AU.

2006 KX38
 
  On June 15, H. C. Lin and Q. Ye failed to do a follow-up observations for a unusual LUSS object, 2006 KX38. As the orbit published in LUSSEC 20, 2006 KX38 was a unusual asteroid with e=0.45. It's possible that this object is a comet, as Q. Ye reported it was "diffuse" (LUSSEC 15). However, the failure on follow-up prove that the orbit was bad. We should go to re-check the previous observations. The orbit is based on a 4-day observations from May 22-26.
