OT J213806.6+261957 appearance of ordinary superhumps

   As pointed out by a number of people (Maehara, Krajci, Kiyota),
ordinary superhumps have grown.  The first hint of growing superhumps
was detected on May 14 in Maehara-san's observation.
Using May 16 data, we have obtained a period of 0.0552(1) d, compatible
with the suggested short period of early superhumps (cf. vsnet-alert 11985).
Since the period of superhumps is likely still unstable now, we will
re-examine all observations when new observations become available.
Please keep you close eyes on this fascinating object!
