Remark:
Mean cycle varies in the range 19d - 33d [04248, 09111].Depth of eclipses 0.25m V; elements of eclipsing systemlight variations: Min = 2437882.8595 + 0.29090950d*E -21d*10**(-12)*E**2 [08854].Sometimes there are light oscillations with periods14.6s - 21.2s and an amplitude up to 0.4% [06102, 09112].
