Three SIR events during March 2016 near comet 67P. The panels show, from top to bottom: solar wind proton density (log-scale), solar wind proton temperature (log-scale), solar wind proton speed, solar wind velocity component parallel to the Sun–comet line, ion counts (color bar is in log-scale showing the exponents for the counts), electron (El) counts, plasma density from RPC-MIP active (nonsmoothed as blue and moving median as black), and passive (red) modes as a function of time. In panels a and b, the black dots show nonsmoothed plasma densities and red points are 50-point moving median. In panel e, the signal near 1 keV is caused by solar wind protons while the signal below 100 eV shows the cometary ions. The green vertical lines delimit the SIR intervals. Time axis format is [YY/MM/DD].
