Poznámka:Data taken by Nancy Barraza, Farid Char and Juan Pablo Colque. Data reduction carried out by Eduardo Unda-Sanzana. We took images in groups of 10 exposures of 15 s each (dead time ~15 s too). Then we added the images using Starlink producing one combined image for every 10 exposures. Finally we carried out differential photometry on the combined images using two constant stars nearby. Transit length 128 minutes adopted to findout midtransit time.
