HAT-P-3b Exoplanet transit

The fit seems to match the predicted parameters in this case. Terrible seeing made guiding very poor (1.2″ usually get 0.5″) and strong moonlight made it messy data but the software was still able to pull a good fit out of the data. This graph is the reprocessed version by the ExoClock team, but very similar to the original.

“Highlighted observations

There are quite many interesting observations thanks to all of you. For this month’s issue, two are the highlighted ones, for WASP-104b. This is a planet that was marked with a medium priority and there are only few observations since its discovery. The two observations were carried out at the same date by two observers at different locations. The uncertainty on the predicted mid-time (shown with red) was quite high. Both observations show a time shift of roughly 15 minutes. This is a good example of how simultaneous observations can contribute to cross calibrate the results. We will reanalyse the data to achieve the highest possible precision.

Congrats to our members Mauro Calo from Italy and Mark Phillips from the UK for their observations!”

The ExoClock team reprocessed my data to give a more accurate representation so is different from my initial report.
