Survey planning page on the SAGUARO TOM, including an Aladin Lite viewer showing three groups of 12 planned fields (red, green, and blue), the 90% credible region contour for S230904n (purple), and the current positions of the Sun (gold) and moon (silver). The radii of the Sun and moon markers roughly represent their respective exclusion regions, although these are distorted with respect to the Mollweide projection. The purple dot near the top left of the map shows AT 2023rkw, suggested as a possible EM counterpart by Necker et al. (2023) but then classified as a Type Ia supernova by Anand et al. (2023). The planned fields are listed in a table at the bottom of the page, with their probability, rank order in our plan, time requested (if any), and time first observable in UT.
