Very good
However, you now have to show the proof to your assumption that the star is a typical beta-Lyrae variable. How does the light curve that you've generated compare to the typical light curve of a beta Lyrae variable. What does the journal literature tell you and how can you fit what you've found into the accepted theory and observations.
This is what you have to write down in your report. This is how you show that you've done the work and followed it up with the study of the literature in order to prove the assumptions about the star that you've made. Preferably, a scientist would've done some previous reading on the subject before they did their observations, but you wouldn't be in a position to know or do that. I think though you'll be able to produce a very good report on what you have done
