SDSS J124058.03-015919.2: already showed ordinary superhumps?

   The hump profile since May 1 looked like singly humped,
i.e. resembled that of ordinary superhumps.
I obtained a period of 0.02613(1) d from observations
between May 1 and 3.  There was a sharp maximum with
a full amplitude of 0.05 mag.  The period was 0.7% longer
than the orbital period and the object appears to have
already shown ordinary superhumps.
