(1993 Jan. 4)
subject: observation of T Leo
T Leonis
CCD photometry of T Leo was obtained on Jan. 3. Following preliminary
results will be interesting to you.
* The mean magnitude was V=11.6 (based on GSC V=11.9 star).
* decline by 0.15 mag in 4 hr observation
* Hump structures with an amplitude of 0.11 mag persisted.
The hump maxima were seen at 3.762, 3.820, and 3.880 UT.
The profile resembles superhumps (steeper rise).
* The hump maxima are well represented by the following formula.
Max UT = 2.806 + 0.05965 E
The period is significantly longer (by 1.4%) than the orbital (0.058819)
one, but is still different from the previously reported superhump
period (0.06411).
