MisV1443: evolving ordinary superhumps

   Kiyota-san and Maehara-san have reported new observations.
The data on Jan. 10 indicate the emergence of singly-peaked superhumps.
Since the object was already in bright outburst on Jan. 2, the present
transition to a phase of ordinary superhumps is not unexpected.
The mean period of ordinary superhumps is 0.0576(3) d (not yet well
determined due to the short baseline) and amplitude is 0.09 mag.
The longer period of early superhumps (vsnet-alert 12585) may have
been from a short baseline and a contamination by emerging (stage A)
superhumps.
