Abstract. Limit length to one page. The text is single line spaces with Times New
Roman size 12 and the paragraph justified. Figures (see below) and equations are
welcome, but not required. References1 go to the bottom of the page as footnotes. The
solar Vacuum Ultraviolet (VUV; < 200 nm) radiation induces photoemission from the
surface of the Moon, Mercury and other airless celestial bodies. This process charges the
surface positively and generates a near-surface photoelectron plasma sheath. Solar
activity is highly variable in the 70-100 nm range where the photoelectron yield peaks.
Available data for high-resolution solar UV spectra and lunar grain photoelectric yield
are combined to calculate the variation of photoelectron emission with solar activity. The
results show that extreme solar flare conditions can increase photoelectron emission
several fold. The consequence of higher photoelectron current is increased surface
potential and stronger electric field that is likely to increase the electrostatic mobilization
of lunar dust.
