[vsnet-ecl 14] Re: LD282
Chris Lloyd,
Several AAVSO observers and myself have been observing LD282 for sometime
now. We have several times of minimum , two of which are CCD. I myself
have observed ( with CCD) the secondary eclipse which is very close to 0.1
V. Your Ephemeris for LD282, T(minI) = 2451421.422 + 1.192840xE, is very
close to the figures we have been using... 2451408.3045 + 1.19286+E.
Peter Guilbault , pete1199@loa.com , has been observing LD282 visually for
two seasons now and has a complete light curve. I have observed 40% of the
light curve to date with my CCD. Timo Kinnunen has sent his observations
to Peter. We intend to present our findings at the October meeting of the
AAVSO. We also will submit an IBVS at the end of this observing season.
Anyone sending their observations to myself or Peter will be included and
properly cited in our reports.
Congratulations to you, Timo Kinnunen and Margareta Westlund for your
accurate work.
