MM Hya: constant period

   Akazawa-san and Maehara-san have reported further observations.
Despite the general decrease of amplitudes (0.25 to 0.12 mag),
the superhump period has been relatively constant at 0.05871(2).
It is very unusual for this short-Porb object to show such a constant
period at this stage (we could expect a positive Pdot).
Further intensive observations are strongly encouraged to see the
reason of this difference from other SU UMa-type dwarf novae.
