The sunline on the lunar horizon

~Lunar horizon glow looks eerily similar to the sunline on Arctic Earth

                      Surveyor 6 , November 6 1967 lunar sunset on the Western horizon.
There is something very familiar about this,  of course its the sunline.   But wait there is
apparently no atmosphere on the moon.   The theory suggesting electrically charged dust causing a sunline is questioned here.  Of all EH2r records from a significant database of Earthly sunsets (from polar and temperate zones),  none have given a sunline due to dust,  it does not happen.   Sunlines are a pure atmospheric optical refraction effect.  

      To the untrained eye, it is hard to say which of these two pictures is from the moon or Earth,  the moon shot (left) should have a pitch black sky, and the Earth's brighter atmosphere gives away the polar sunset (right).  There is no doubt about moon dust on the lunar picture (left) given by the small aureola, similar to haze or dusty horizons on Earth.   But the sunline is unmistakably identical.  The rocky lunar surface is very similar to the sandstone Arctic gravel hill 3.5 km away from camera:

Arctic hill sunset October 14, 2014.  Remarkable
refraction effect caused a few km away,  not through a long distance of atmosphere.  But caused by air less than half a meter above the gravel hill.  It took very little gaseous molecules to cause this effect.

There was a very faint or negligible corona  because there was no dust or ice crystals (it was too warm for crystals to form).  There was light winds as well,  frozen ground reduced dust levels greatly almost completely.

   The absence of dust here contradicted the presumption that sunlines
are caused by dust.  They exist because of gas.  Until a dust sunline can be replicated,  a dust sunline is simply an un-observed theory on Earth.

    There is an unmistakable structure with any sun line,  if you zoom you will see red line layered below the brighter yellow which can be at times blue or green.  The red has to be below because there is less bending of red light,  it is a refraction effect.  Consider the same photo with no significant atmosphere and the line would appear greatly brighter than background.

  A careful look reveals almost identical sun line between Earth and moon,  the difference is of course in part due to different optical equipment utilized.  The moon's aureole was illuminated by moon dust,  but the sunline is a totally distinct feature.  Has nothing to do with dust as seen on the edges of the moon's sunline especially at left,  where the aureole dust above hardly makes a glow.   There is also a photonic disturbance below the main brighter moon sunline suggesting a red imprint of course not recorded as such.
     The actual physics of dust bending light uniformly would be quite exotic,  unless unique to the moon,  dust scatters light when photons are present.  The theory suggesting
that light gets bent,  creating a later sunset, indeed introducing focused photons making a layer of the micro horizon bright  has nothing to do with particulates.

       It is not inconceivable that the moon may have some daily outgassing similar to comets during their celestial orbits approaching the sun.   On the lunar surface there is a daily very steep rapid change in temperature,  a heat cycle familiar in the Arctic,  where micro surface thermal variations are responsible for great photon redirecting.  There is also an atmosphere on the moon,  said to be very weak,  13 degrees of magnitude weaker than on earth,  perhaps not always the same or uniformly everywhere on its surface. WD October 15-16, 2014
