    calm as a whole, but the ID 2114.41-21114.86 2114.44-2114.67 between 30-5 days study this star show significant changes in the light curve .star .tak also, interestingly very small gap between the potential of transit have small change in the light curve. Judging by the frequency of transit can be assumed that most likely we are dealing with eclipsing binary star but then what is the nature of the change of the second signal?

    There is only one feature, but it appears in Q1-2 and Q1-3 because there is an overlap. The profile is a little ragged but roughly V-shaped, so I agree this is probably an eclipse

    The close up of the star also appears to show a binary.
