UPDATE AND NOTICES FROM POST-PERIHELION

 After a possible second outburst of comet C/2022 E3 ZTF and a possible transition of predominant volatile change to Water, the comet is currently at an apparent mean visual magnitude of +5.5. In previous posts, I commented on the possibility that it did not exceed magnitude m1=+6, but an unforeseen second outbursts has increased its magnitude by an average of +0.5 more than expected. A first outbursts in T-11 days, and a second outbursts in T+6 days, with respect to perihelion, it is logical to think that the light curve should be symmetrical with respect to perihelion, but this is true in very few cases, my This hypothesis proposes that the axis of rotation is tilted with respect to the cometary orbital plane , which means that the comet nucleus is exposed to different hemispheres before and after perihelion , if the two cometary hemispheres contain different amounts of dust and gas the rates of gas and dust emission is also logical to vary and therefore its light curve.
