    Hi everyone.

    With the Noctilucent Cloud season fast approaching hopefully in 5 to 6 weeks time I presented a wide ranging talk to Astronomy Ireland at Trinity College Dublin entitled “Clouds at the Edge of Space: An Insight to their History, Formation & link to Solar Minimum”    see http://www.astronomy.ie/lecture201904.php

    During the talk I started with alleged NLC observations in the mid 19th century and went on to examine the volcanic eruption of Krakatoa in 1883 and how this affected the upper atmosphere as well as examining NLC’s and there connection to greenhouse gases & Climate change. 

    Other topics I included was how the Solar cycle affects NLC formation, a possible upcoming Deep Solar minimum, similar yet strange high atmospheric phenomena and finally a look at how observations of NLC displays were recorded at meteorological stations throughout and the Republic of Ireland from 1965 to 1975. I also used photos and data from a huge collection of newsletters and NLC/Aurora manuscripts that I found in my local meteorlogical station recently with some going back to the 1950’s.  

    You can view the full 70 minute presentation although not in HD at https://drive.google.com/open?id=1yhDrFB8gFEuzk1NLkkj59f3smWvrUQWx

    Hope you enjoy the talk despite my west of Ireland accent.

    Great. 

    I gave a similar, though much less detailed talk to my local society a few years ago, I would loved to have been able to listen to your talk in advance of that to help me prepare. Sandra is always very helpful though so I picked her brains for ideas and images.

    Thanks for sharing. Great stuff.

    James
