ASASSN-18aan: orbital and superhump periods (SU UMa star at Porb=0.1495 d)

   Tamas Tordai has reported observations on the next night.
The orbital period is 0.14952(1) d (this will be soon
refined after more data).
The superhump period, as determined from observations
up to now, is 0.1726(2) d, 15% longer than the orbital one!
This excess is so incredibly large, and intensive
observations are urgently requested.
