Subject: V2051 Oph - improved eclipse timings
Dear Astronomers,
the eclipse timings you distributed are too early by about 5 min. You
probably have taken the parabolic ephemeris of Echevarria & Alvarez (1993)
which don't fit over the years. The eclipses seem better calculated with
their linear ephemeris:
HJD(eclipse) = 2444043.680190 + 0.0624278870 * E
Eclipse timings for the next days are attached.
Best regards,
Sonja.
