Tyc 5881-1190-1

Two nights ago I was imagining TYC 5881-774-1 15 LY distant star and when I did photometry on the images, the other star TYC5881-1190-1 come up with this light curve. I don’t know if I should trust my results because – the star is saturated (it was not target) and my planetarium program list it as constant star.
Any comments appreciated
