  Blanco-Cano et al. (2018) intended to find a type of transient event in the
solar wind before the terrestrial bow shock using a special type of simulation.
However, the simulation results cannot reproduce the main features of the
event. Based on the remarks described below, I am sure that the features in the
simulations are not those type of events. The VLASIATOR code simulated
proto-SHFAs.
