Fig. 5.From: Solar wind electron interaction with the dayside lunar surface and crustal magnetic fields: Evidence for precursor effectsSelenographic map of the foot-point locations of electron observations (same data set as Figs. 1–3). Blue points indicate observations with no upward-going flux enhancement, green points indicate observations with apparent upward-going conics, and red points indicate observations with upward-going beams. Black contours show 10 nT, 20 nT, and 50 nT levels of surface crustal magnetic field magnitude.Back to article page
