Favourable apparition suggested from CALL website with
opposition mag. of 12.3m on 27/05. Previous derived period of 12.321h
with U=2. The last session on 4th July shows that the curve must be
bimodal with more refined period. 2 possible periods with the second being
12.321h. Longer observing sessions required to nail down the correct period. |
