Residual O–C diagram of TU UMa after subtracting the first LiTE model (top panel) and second model – only photoelectric, CCD, and DSLR observations (bottom). Black circles and blue stars display maxima adopted from the GEOS database and new maxima determined in this work. The jump in the general trend of O–C in the range from JD 2 425 000 to 2 429 000 (top panel) might be an indication of a more complex period change.
