LIGHT CURVE REDUCED OF COMET 46/WIRTANEN SCIENTIFIC RESULTS
Based on my analysis of the reduced light curve of comet 46p, based on 990 measurements, being the world's largest light curve, the preliminary scientific results are: Estimated diameter 0.96 kms, Estimated active surface area ~ 50km2, Water production rate Q (H2O) ~ 10 ^ 29.5 mol sec = 5 tons per second of water, it is observed that ar = 1.25 au, there is a change in the predominant chemical volatility being Q H2O> Q CO +, these results are preliminary, until completing the light curve, and are based on the following scientific references: Sosa, Fdez (2011), Yang (2008), Navarro (2018), MPC / IAU, Cobs.si, Observerscometas yahoogroups.com (Navarro owner).
