Hi,

I've had IR Com at 17.18 on 2014 May 24.9257UT. Is IR Com fading or have I witnessed an eclipse? Is there an eclipse prediction of IR Com around?

Cheers,

Eddy

Hi Eddy,

The predicted time of eclipse is HJD 2456802.426, based on the ephemeris in VSX.   This agrees with the time of your observation.

Hi Patrick,

Thanks for the info! I assumed it was an eclipse. How deep does these eclipses actually get?

Cheers,

Eddy

The paper by Feline et al. http://adsabs.harvard.edu/abs/2005MNRAS.364.1158F mentions an eclipse amplitude of around 2 magnitudes.
