Could it be transit between 1984 and 1985.5 BKJD?

201438747: it's possible this is a long period gas giant Neptune size or greater, but one blended transit makes that rather speculative. I tried to estimate the star size and period, but looked like it would take a lot of computer time to run through all possible combinations. So this is a best guess for now from a one hour run. Hope this helps. (edit: peak transit flux reduction is ~0.134%)
