Target of opportunity in the same field as 2066 Palala. Previous period
derived by Behrend
et al.(2008) at 5.37h with U=2- with amplitude of 0.11m showing a
monomodal light curve indicating a polar orientation. Current work showing a
more favourable orientation. |

Call target in 2007. Followed up work in 2008 apparition.
The 2008 data taken on 15/07 and 17/07 were linked using the same
comparison stars. So does the data on 17/07 and that on 18/07. This confined
the period to 16.7 and later confirmed with subsequent collection of data.
The bimodal light curve formed fit well with a period of 16.6076h. |

CALL targets. Previous data shows a period of
11.16h+/-0.09h(Behrend
et al.(2008)). Work in collaboration
with Dr. Michael
Fauerbach. 3 nights of combined long
run between US and Australia allow us to constrain the period to the one
described here. Any further refinement of period has to be done in the next
apparition perhaps with collaboration with even wider geographical location.

Call target. No known period. Fit well into a trimodal curve. Initially
shown to be a bimodal light curve of period 3.157h appear to be caused by
significant error from earlier poor quality data. This also caused the
false detection of an event. |

Target was suggested by Behrend as a suspect binary. attenuation noted
at the end of session 868 is associated with poor atmospheric condition at
an altitude of about 30deg. This color effect was later reprocessed and
removed that eventually neutralise the light curve. |
