  We describe a new quiet-Sun phenomenon which we call "Quiet-Sun Ellerman-like
Brightenings" (QSEB). QSEBs are similar to Ellerman bombs (EB) in some respects
but differ significantly in others. EBs are transient brightenings of the wings
of the Balmer H-alpha line that mark strong-field photospheric reconnection in
complex active regions. QSEBs are similar but smaller and less intense
Balmer-wing brightenings that occur in quiet areas away from active regions. In
the H-alpha wing we measure typical lengths of less than 0.5 arcsec, widths of
0.21 arcsec, and lifetimes of less than a minute. We discovered them using
high-quality H-alpha imaging spectrometry from the Swedish 1-m Solar Telescope
(SST) and show that in lesser-quality data they cannot be distinguished from
more ubiquitous facular brightenings, nor in the ultraviolet diagnostics
currently available from space platforms. We add evidence from concurrent SST
spectropolarimetry that QSEBs also mark photospheric reconnection events, but
in quiet regions on the solar surface.
