November 12 – 14, a Saturn-like planet outside of our Solar System, or exoplanet<\/em>, will give both professional and Citizen Astronomers an opportunity to gather new data about a mysterious world.<\/span><\/p>\n HIP 41378 f is what astronomers call a \u201csuper-puff\u201d planet, meaning that it\u2019s large but is predicted to have a very low density.

If you\u2019re in Western Europe or Africa you\u2019ll be able to catch the start of the transit, and if you\u2019re in Eastern Europe or Asia, you should be able to see the end of it.

You can use this <\/span>deeplink<\/span><\/a> to observe for two hours (the recommended minimum observing time), or you can input the row\u2019s recording settings manually to break your observation into one-hour increments (this may improve your telescope’s tracking). <\/span><\/p>\n <\/span><\/p>\n Lastly, when you are done observing for the night, please submit this short REPORT FORM<\/a> so we know to process your data.<\/span><\/p>\n If this is your first time observing an exoplanet transit, first check out our Exoplanet Tutorial <\/a>page for an overview of the techniques involved.
