NLC Season now in full swing

NLC 19/06/19 Andy McCrea

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.

Apollo 11

Wednesday 17th April marks the date of the 45th Annual General Meeting of the Association. The purposes of the meeting are to review the activities of the past year, elect a new Council for the coming year and for the Council to receive feedback from the membership on how they - that's you - would like to see the Association develop.

 

This year there will be two additional features to add to the formal business.

Lecture: Weds 3rd April - Prof Alan Fitzsimmons - "DART & Hera - Moving an Asteroid"

Prof Alan Fitzsimmons

Over the past few decades, our knowledge of how to handle the threat posed by Near-Earth Objects has increased enormously. Astronomers surveying the sky find over 150 new NEOs per month. We understand the gross characteristics of that population; how many there are, what they are made of, their overall structure and how their orbits change. Now the final stage of threat assessment is under way. In three years time, humanity will test whether it can move a small asteroid for the first time.
