Example of the consistency of followup observations made on the same date of 2010-10-20/21 by different observers. This is an example of a “regular” transit. Lighter dots are for the data of Claudio Lopresti (ETD), whereas the heavier ones for those of Ramon Naves (ETD). Continuous line shows the model fit to the grand-averaged transit light curve. The agreement between the two datasets is very good. Both indicate a small but significant brightening in the middle of the transit.
