The observation of protons in lunar wake by SARA experiment on Chandrayaan-1, for one orbit on 18 July 2009 when the IMF was parallel to solar wind velocity. a The top panel shows the energy-time spectrograph of the observed protons where the population marked ‘A’ is the one observed in the lunar wake. Middle panel shows the solar zenith angle, and the bottom panel shows the IMF orientation during the observation. b The trajectories of the observed protons back-traced from the location of observation [from Dhanya et al. (2013)]
