As mentioned by Martin, the IUAA had their General Assembly in Dublin in 1978. Also there, Patrick Moore gave a public lecture in the Mansion House. I remember it well, as this was my first time to attend an astronomical talk! I am afraid I cannot remember the actual title of Patrick’s talk. I did not attend the excellent IUAA event itself as I had not yet joined the IAS.
Quite a few of the IAS members were involved with the IUAA. My memory was that James Kelly, Ciaran Kilbride, Eamonn Ansbro & Vincent Deasy were the IAS representatives.
The IAUU had very laudable ambitions of setting up worldwide observing sections. However, one problem was they were overlapping (in part) with organisations like the BAA and the AAVSO etc which were already doing a good job.
