Observations of an X1.5-class solar flare taken by Gerry Doyle, Eamon Scullion,
Chris Nelson and Aidan O'Flannagan in H alpha on the 10th June 2014 on the Swedish
Solar Telescope. Image [A] represents the initiation of the flare and was taken
approx. 30 mins before images [B-D] representing different spectral positions in the
scan of the H-alpha 656.28 nm line absorption profile (top left).

Noctilucent or "night shining" clouds, observed over Armagh on the night of
19th/20th June. The silvery, highly structured clouds take many forms: ranging
from delicate feather structures to streamers, ripples and waves, and are only seen
occasionally, always after dark, during the summer months May to August. Scientists
believe that they are caused by sunlight reflecting off ice crystals in the
mesosphere, a region of the Earth's atmosphere lying high above the stratosphere, at
a height of around 80 kilometres.

The war fronts between the hot gas emitted from the massive star Herschel 36 and the
dormant surrounding cold matter create spectacular celestial environments such as
the Hourglass nebula. The shockfront compresses the cold molecular gas, resulting in
star formation and setting the clock rolling on a new generation of stars through
the creation of the Hourglass.
