long tail projecting up from the horizon is a special view, one not
experienced too many times during a lifetime and unforgettable to most.
However to obtain a similar view of an astronomical phenomena we may not
have to wait lifetime. The recent discovery (by amateurs) of a form of
the Aurora (acronym STEVE) can have the same scale and diffuse
appearance that long tail comets can have. The sightings of these auror<span id="yui_3_16_0_ym19_1_1521811521036_9575">al
forms is becoming more common. The attached pictures show these simliar
appearances. The first picture is a combinbation of two images one of
STEVE taken by Gordon Mackie in Caithness Scotland last week and the
other the view of C/2011 W3 Lovejoy at is post perihelion best taken
from Australia. The second picture is one of my own taken of STEVE from
Tarbatness Highland Scotland in 2016. Make you own judgment about the
similarity of appearances. More information about STEVE can be obtained
