<p>It seems they're currently using <em>Kepler</em> and <em>Spitzer</em> and plan to use <em>Hubble</em> in the near future as well as <em>JWST</em> after it launches.</p>

I would have thought that something with $V=18.8$ would be a struggle with K2.

NASA's K2 mission is currently observing Trappist-1 and the data will be released to the public on March-5

<p>The video shared by NASA specifically mentions that JWST will be used to observe the TRAPPIST 1 system. Infact that's going to be one of the prime targets.</p>

I'm looking for something a bit more specific than this.

I wonder if that's now happened?

@uhoh Apparently JWST found out that TRAPPIST has a very thin atmosphere.

Proposals to use telescopes are not public information. Not clear what information you are looking for. Of course most large telescopes on the ground and space have been and will be staring at this object.

@RobJeffries I'm not sure what you mean. Detailed information is usually not available, but there are plenty of cases where it has at least been indicated that the instrument will be used; this was the case with [the Subaru telescope and Planet Nine](http://subarutelescope.org/Topics/2016/01/21/index.html).

(Asked by: username_0 on 2017-02-24)

The recent discovery of [new planets around the star TRAPPIST-1](http://www.nature.com/nature/journal/v542/n7642/full/nature21360.html) happened by observations from 7 ground-based telescopes, as well as the Spitzer Space Telescope. The team of astronomers responsible has noted that there are many relevant parameters which still have large uncertainties, including orbital information and planetary mass. There's also some excitement about possible atmospheric composition.

Are there any *definite* planned future observations of the system? I assume that at some point it will be targeted by the [James Webb Space Telescope](https://en.wikipedia.org/wiki/James_Webb_Space_Telescope), but that won't launch for another year and a half, and it has plenty of other targets.

I'm not looking for detailed information - I know that cannot be easily gathered - but if there are any general mentions, [like this one about the Subaru Telescope and Planet Nine](http://subarutelescope.org/Topics/2016/01/21/index.html), that would be fantastic.

It seems they're currently using *Kepler* and *Spitzer* and plan to use *Hubble* in the near future as well as *JWST* after it launches.
