OW Geminorum / OW Gem
Light curve and phase diagram of the EA/GS type eclipsing binary OW Geminorum / OW Gem, constructed from photometry of 303 images taken with the Open University COAST telescope between 2017 September 22 and 2023 April 7 through a V filter.
Due to poor weather at the observatory, the primary minimum was not well covered, but an enlargement appears below.
The secondary minimum is better covered, and an enlargement of this section of the phase diagram appears below. (Note the differing scales between the enlargements of the two minima.)
Note that the phase of the secondary minimum is at approximately 0.23, not 0.5. This is due to the orbits being eccentric, not circular.
