An excellent display of Noctilucent Clouds was visible from Northern Ireland in the early hours of Tuesday 18th June. As befits the Solar Minimum, this iwas a very high and bright display and an encouraging sign for a good season. This generally runs from the beginning of June until early August. There is some belief that the emission of Greenhouse Gases into the atmosphere is amplifying the displays, paradoically by making the mesosphere colder as less infrared is radiated upwards having been absorbed by Greenhouse Gases.
Keep an eye out to the Northern sky anytime after Sunset and before Sunrise. As the sky darkens theses amazing clouds will make themselves know,
