Comment

object EL CVn

  1. Martin Lehky, 4. 6. 2012
    Duration of primary eclipse DI = 0.08d (1.9h) and duration of totality in primary eclipse dI = 0.07d (1.7h), amplitude Rc = 0.08 mag. Duration of secondary eclipse DII = 0.08d (1.9h) and duration of totality in secondary eclipse dII = about 0.06d (1.4h):, amplitude Rc = 0.04 mag. The shape of the ligtcurve looks like transit of big exoplanet:-)

    Primary minimum 2456014.35129 (Hel) occurs about 0.48 hours earlier than predicted (for elements 2448331.778 + 0.795629 * E)
