Exoplanet TOI 1811.01 - 20.3.2021 at 00.00 - 20.3.2021 at 02.26 Tervakoski Observation number 98054

Visibility II / V

The exoplanet TOI 1811.01 situation update on March 19 had three positive observations, mine and Bruno G. (France), as well as Philippe RONCERET (France). Here, a combined light curve showing that the transition time is later than the prediction of 16.5 minutes. With measurement error +/- 1.6 minutes. This is a potentially exciting discovery because variations in transit times may be due to the presence of other planets in the system that either slow or accelerate the rotational speeds of the passing planets by gravity. These are only preliminary results and we will probably get confirmation when the data analysis is completed later. 14.4 we observed the same object, in that case there were as many as 13 observers, hopefully positive results will be found.
