Hi everyone, Hope you are all well! This email is to inform you about a new campaign we start in order to observe K2-19b, a planet that shows TTVs (it has an additional planet K2-19c). We would like to observe as many as possible of the upcoming transits of K2-19b "https://www.exoclock.space/database/planets/K2-19b/. The upcoming transit is happening between Wednesday the 1st of March 21:22 UTC and Thursday the 2nd March 02:38 UTC (the observation occurs the night between Wednesday the 1st of March and Thursday the 2nd of March). There is no limitation for the size of telescope, however the transit may not appear in your scheduler. Please organise the observation yourselves by checking the ExoworldsSpies scheduler to see if the transit is observable from your location (you should use a telescope aperture of at least 13 inches, otherwise the planet will not appear). https://www.exoworldsspies.com/en/scheduler/ Remember that the exposure time should be longer than your overheads (dead time between exposures). To be able to have a decent exposure time you may need to use a filter -preferably Red Cousins- or to defocus your telescope. You wouldn't need to do anything special in terms of the analysis, just upload the observations to ExoClock in the normal fashion. Please indicate in the comment section that the observation is "part of the K2-19b campaign". In the meantime, let us know if there are any questions. We really hope to get some clear skies during this night! Anastasia & Angelos
