Impact of Light on Environment and Health

Fast large aperture photometers directed at the zenith on clear nights near Minneapolis have recorded many light pulses in the millisecond time range, but aside from man‐made events these were almost entirely due to Rayleigh scattered distant lightning, with a residual very low rate (<0.1/hr) of unidentified pulses. We believe that 1 ms light pulses seen in several previous experiments (FAP's) may also be mostly Rayleigh scattered lightning, rather than fluorescent light due to electron precipitation from lightning‐induced whistlers as previously discussed.
