fiS C IENCE Q UESTIONS ( EXCER PT FROM PROPOSAL )
3D structure of photospheric and chromospheric
eld in different regions: how force-free is the eld?
How different is the quiet Sun (coronal hole vs.
normal)?
How ef cient is eld-line braiding (camp res)?
How high is the wave ux travelling into
chromosphere and corona?
How common are small scale jets?
How does magnetic ux emerge and how is it
removed?

To create an observing plan for Sunrise III,
we have formed a Science Working Group
(SWG) with members from the PI and CoI
institutes.
Currently we are in the process of collecting
scienti c ideas
We invite you all to submit ideas
(submission deadline: May 15 2021)
Fill in a google form:
short description of the idea
clickable selection of key instrument parameters
link to form: write mail to me
lagg@mps.mpg.de; or write your e-mail address
into the chat
All the collected ideas will be discussed in Visit MPS homepage:
the SWG and we will come up with a
consolidated observing plan. https://www.mps.mpg.de/sunrise-obs-plan
