I was in the process of aligning old data with new data, when I noticed that a star had become noticeable smaller within the last year. I then tried to figure out if this was a variable star, though it seemed a bit drastic to me. My next guess was that somehow my data from last year was faulty. The new data is Luminance, so it should show the data in all wavelengths, therefore it could not explain the star being smaller. I didn't come any closer an answer... So...
I got quite curious in what could do this. If it was something I missed. I know that there must be someone in here that have the answer, and I'm not afraid to embarrass myself in the search for an answer
Most of all it could be fun to see if any of you have data showing the same?
