Noctilucent Clouds
Boher, Limerick. 3AM
09.06.07
These noctilucent clouds, also known as polar mesospheric clouds, are bright 'cloudlike' atmospheric phenomena
visible as the name suggests, at night. Tipically seen in the summer months around midnight.
The phenomena is thought to be caused by various particals in the mesosphere bieng illuminated by the sun, long after sunset.
It was once thought that they were composed of volcanic or meteoric dust,
but they are now known to be primarily composed of water ice (confirmed by UARS).
They appear to be a relatively recent phenomenon—they were first reported in 1885, shortly after the eruption of
Krakatoa
and it has been suggested that they may be related to climate change.
At least one researcher, Dr. Michael Stevens of the United States Naval Research Laboratory,
believes space shuttle exhaust may contribute to the formation of noctilucent clouds.
