Minor Planet Center published the orbit of 2006 KY38 (LUSS-38), it's a Mars-crosser (q=1.44), but with flag of "E-assumed", the orbit could be an approximate one. It's still possible that this object is a near-earth object, for the residuals in the third night is large. Further observations needed.

  From this very first orbit calculation, 2006 KX38 shows some interesting character, with a high e (e=0.45), it can come quite close to Mars (Mars MOID about 0.03 AU). Furthermore, the object reported as a "diffuse" object on May 22, but no similar character detected on May 25 and 26. More observations of this object is required.

Observer details:
D35 2 Lulin Observatory-Super Light Telescope.  Observers H. C. Lin, T. C. Yang, Q. Ye.  
      Measurer Q. Ye.  0.40-m f/8.8 Ritchey-Chretien + CCD.

  From May 6 to May 12, Hung-Chin Lin, Ting-Chang Yang and Quanzhi Ye of Lulin Sky Survey used the 0.4-m Ritchey-Chretien telescope to do 73P complex survey. Quanzhi Ye reviewed the images, and take measurements of 92 objects. Here are possible linkages for each of them:
QY65733: 73P-Y.
QY65A48: 73P-G.
QY65A49/A/B/C: 73P-AU. This fragment seems to have been disrupted into four.
QY65A4F: 73P-J.
QY65A52: 73P-K.
QY65A58: 73P-M.
QY65A5C/G: 73P-H.
QY65A5D: Far from the predict position of 73P-BO.
QY65AEJ/K: 73P-AP. Two close fragments.
QY65AEL/M: 73P-BC. Also very close.
QY65AEO/P: 73P-BN. Same as above.
QY65AEQ: 73P-R? However some distance.
QY65BEf: 73P-V? Far from the predic position.
QY65CEH-N: Large amount of mini-comets around 73P-X. However on the images of 9/10/12,  none of them was found again.
QY65CF2: 73P-BC.
QY65CF3/4/5: 73P-AP. Now three fragments near the predict 73P-AP. 4/5 are very close.
QY65D57-9: Near 73P-AJ but none of them fits the predict position.
QY65DD1: 73P-AE.
QY65DD7: 73P-AI.
QY65DE2: 73P-AL.
QY65DEA: 73P-BO.
QY65DED-F: 73P-AM, however seems it had disrupted into three pieces.
QY65DEI: 73P-AN.
QY65E01-3: 73P-BH. Three faint fragments around Vmag18.0.
QY65E0A: 3.1E/1.8S of 73P-BM.
QY65E0F: 73P-BO.
QY65E0G-I: The three companions of 73P-AM were observed again.
QY65E12/3: Near 73P-AJ.
QY65E21: 73P-AM. Only the biggest companion was observed on May 12.
QY65E2A: 73P-AT.
QY65E2d: 73P-AY?
QY65E2e: 73P-BG?
QY65E32: Near 73P-G and 73P-AU, but none of the two was observed.

We have discover one more fragment of 73P, fragment AW. It's a join-credit with Cordell-Lorenz Observatory and Catalina Sky Survey. Other interesting discoveries include fragment AQ, which is the second fragment of fragment B.
