Reminder: One year ago Parker Solar Probe (PSP): 4 th perihelion Alignment: 27 -28 Jan 2020 Window: 21 Jan - 2 Feb 2020 Add 3 -4 days for propagation to 1 AU Aimed for 4 MMS orbits, spanning 25 Jan - 8 Feb 2020

an additional request – slightly expanded SW SROIs Expand SROI 2 from the nominal 3 -4 SW hours to 8 -12 SW hours per orbit – when that can be accommodated w/o impacting magnetosphere, magnetopause, foreshock, and bow shock observing times. • SITL selection guidelines and downlink budget would remain as previous, the increased runtime provides additional SW shock selection opportunity. • Runtime remains below Prime mission hours Phase #orbits time in fast survey (hrs) 1 B 136 2034 2 B 43 2105 3 B 42 1055 4 B 43 1250 5 B 43 1441 6 B 44 delta is ~310 hrs or ~1550 -1750 in total, including PSP and interstellar neutrals opportunities Implemented on next slides by increasing duration of SROI 2
