NASA citizen scientists from all over the world have used EXOplanet Transit Interpretation Code (EXOTIC) to reduce 71 sets of time-series images of WASP-12 taken by the 6-inch telescope operated by the Centre of Astrophysics | Harvard Smithsonian MicroObservatory. Of these sets, 24 result in clean Transit light curves of the WASP-12b which are uploaded to the NASA Exoplanet Watch website. We use priors from the NASA Exoplanet Archive to calculate the ephemeris of the planet and combine it with ETD (Exoplanet Transit Database) and ExoClock observations. Combining the Exoplanet Watch, ETD, and Exoclock datasets gives an updated ephemeris for the WASP-12b system of 2454508.97872 +/- 0.00003 with an orbital period of 1.0914196 +/- 1.7325322e-08 days which can be used to inform future space telescope observations.
