Remark:
The member of the Hyades cluster.
EA/D/(RS + WD) + XP. d = 0.0625P.
There occurs a total eclipse of the white dwarf in
Min I (A = 0.04m V, 0.36m U).
P var. Min I = 2440612.67083 + 0.52118321d*E
(JD2440570 - 970) [06250]; Min I = 2440898.80038 +
0.52118376d*E (JD2440880 - 41360), Min I =
2441665.46153 + 0.52118329d*E (JD2441660 -
42100) [10058]; since JD2441900 - see Table.
Wave-like distorsion with the amplitude from 0.05m
up to 0.27m and with the period close to the orbital
one is observed in the light curve outside eclipses;
sometimes there are also flares. The wave is migrating on
phase in the direction of phase decreasing
with a migration period of 191d [10060] or ~250d
[10061]. The period of white dwarf rotation derived
through X-ray observations Ppuls = 554.73s [10062].
