ENLIL Solar Wind Prediction - PUNCH
Polarimeter to Unify the Corona and Heliosphere (PUNCH) is a planned mission by NASA to study
the unexplored region from the middle of the solar corona out to 1 AU from the Sun.
PUNCH will consist of a constellation of four microsatellites that operate in low Earth orbit
since August 2022.
See the project website:
punch.space.swri.edu
for details.
Selected animations show a hypothetic global context for PUNCH spacecraft on August 2022.
Historic observations are used to calculate the radial magnetic field and solar wind velocity
at 21.5 Rs by the GONGz-WSA_2.2 model and to fit geometric and kinematic parameters
of coronal mass ejections (CMEs) at CCMC/DONKI.

a heliospheric simulation from 2022-07-19 to 2022-08-31 (i.e., within
the same period of the 11-year solar activity cycle).

Space weather monitors: PUNCH (at near-Earth), Solar Orbiter (SOL), and STEREO-A (STA)
and heliospheric disturbances at the ecliptic from 2022-08-01 to 2022-08-31.

field lines.

Synthetic white-light images at PUNCH (right) and solar wind density at ecliptic (left) from 2022-08-01 to 2022-08-31.
Running differencing has 2-hour cadence.
Dashed-green lines show an extent of the combined FOV (elongations: 2.5-47.5 degs) and the solid green lines show elongations
at 20, 40, and 60 degs.
