Giant Planet Visibility Windows

Calculations of Giant Planet visibility for Cycle 1 using the JWST Moving Target Visibility Tool

Note: use the following sequence to prevent crashing MacOSX with this python tool: jwst_mtvt 599 --save_plot jwst_jupvisibility.png > jwst_jupvisibility.txt

Note: the break between JWST cycles is expected to be June 30th to July 1st.
