UMAIY 20060406.333  170CR Scp
UMAIY 20060407.308  169CR Scp
UMAIY 20060408.211  133CR Scp
UMAIY 20060409.202  130CR Scp
Instrument: University of Iowa, Rigel Telescope (0.37-m Cassegrain)
Sequence: Henden and Sumner (R magnitudes derived from V and B-V)

T_mid-eclipse = HJD 2451570.85376(2) + 0.07390897(5) E
(Steeghs et al. (2003) MNRAS 339,810)
 
Mid-eclipses are expected for 2006 Apr. 8.9618 UT,
