AL Com early superhumps, changing profile
We have received additional data from the Brno team. A quick look
at the data on Apr. 24-25 shows again singly peaked humps. The best period
from this night's observation is 0.0560 d, which suggests that these
modulations are early superhumps with changing profiles. However, this
may be a suggestion of the emergence of usual superhumps, what are observed
in all SU UMa stars (cases are known usual superhumps start with a period
close to the orbital period, cf. T Leo in 1993, PASJ 49, 583).
Continued observations are very encouraged. More detailed analysis,
together with other incoming data, will be presented by Ishioka-san et al.
later.
