==Motion==
A reporting of motion of the LF was common among astronauts who experienced the flashes.<ref name="Fuglesand2006" /> For example, [[Jerry Linenger]] reported that during a solar storm, they were directional and that they interfered with sleep since closing his eyes would not help. Linenger tried shielding himself behind the station's lead-filled batteries, but this was only partly effective.<ref name="Linenger2000">{{cite book |title=Off The Planet: Surviving Five Perilous Months Aboard The Space Station MIR |publisher=[[McGraw-Hill]] |first=Jerry M. |last=Linenger |date=13 January 2000 |isbn=978-0-07-136112-5 |url-access=registration |url=https://archive.org/details/offplanetsurvivi00line }}</ref>

The different types of directions that the LF have been reported to move in vary across reports. Some reported that the LF travel across the visual field, moving from the periphery of the visual field to where the person is fixating, while a couple of others reported motion in the opposite direction. Terms that have been used to describe the directions are "sideways", "diagonal", "in-out" and "random".<ref name="Fuglesand2006" /><ref name="Sannita2006" /> In Fuglesang ''et al.'' (2006), it was pointed out that there were no reports of vertical motion.<ref name="Fuglesand2006" />
