Sarychev Peak Volcano eruption [Kuril Islands Russia northeast of Japan] on June 12 2009 sends sulphur cloud into atmosphere that soon circles the northern hemisphere including Europe causing beautiful sunsets/ sunrises seen here from SW London. The blue noctilucent cloud seen about this time is a summer solstice phenomena from high latitudes unrelated to the volcano's eruption.
Nice video, 5 stars.
