This was posted to the Discussions on Astronomers Without Borders.  CloudyNights is a much larger community of engaged amateurs.

 

 

I work on Exoplanet Watch, a citizen science project run by NASA's Jet Propulsion Laboratory. We have an observing campaign for HD80606 on December 6-9, 2021, to watch a 12-hour transit of an exoplanet that only orbits its star every 111 days. We are part of Las Cumbres Observatory's Global Sky Partners program.

 

I'm not able to book LCO time for December 8 or 9 from 1am-5am UTC, because of weather issues in Spain that will require the Tenerife telescope to be offline then. Does anyone have telescopes in Europe, North Africa, or Asia that will have better weather on those days so that collectively we can observe the whole transit of HD80606b?

 

We have telescope time scheduled for the pre-transit baseline and part of the middle of the 12-hour transit, but it's important to catch the beginning and end of the transit so that we can confirm the mid transit time. The accurate timing of this exoplanet transit is important, because NASA's James Webb Space Telescope is planning to observe this exoplanet on a subsequent transit, after it launches and deploys. Let me know if you have a telescope that can observe HD80606 on or around December 7, [2021]. Thanks!

In Ursa Major around 9 hr +50degrees. It rises in Texas around 19:30 CST and would take 2 hours to rise above 30 degrees AZ for critical photometry. Not a North American target for the full transit or even filling in the last half fully, thus the call to Europe.

Given that this exoplanet was discovered 20 years ago, I am surprised that the transit timings are not already known to high precision already or is there something odd about it?

There seem to be a couple of JWST proposals on this target:

Yes I understand why it might be an interesting target for JWST, I was just surprised that  the transit timing was not already known to sufficient accuracy to be able to schedule the observations.
