1. IAA Public Lecture Meeting, 2 November; "How We Tell The Time", by Dr David Malone, NUIM. The connection between astronomy and time is as old as astronomy itself, since the day and the year are determined astronomically, and the month has an obvious astronomical connection. But do you know that there are 5 different times for the length of a month, and of a year? And at least 20 different ways of measuring time itself? (AST, ET, DST, GMAT, GMT, GST, JD, LST, LST(2), MJD, MST, ST, TAI, TCB, TDB, TDT, TT, UT, UT1 and UTC. And you also have to allow for Delta T! And measurements must be made with respect to ICRF2 And, of course, it's all relative!
But don't worry - the talk won't be addressing all those, and it will be at a simple and popular level.
Why are there so many different 'types' of time, what are they used for (some are now obsolete, BTW), and how do we measure time anyway?
This lecture will throw some light on something we take for granted, but is in fact far from simple!
SYNOPSIS: Knowing the date and time is a question that is tightly tied up with astronomy, combined with some history, politics and a bit of physics. This talk will give a summary of how the calendar and clock we have today has changed from ancient times right up to 2016.
TIME: 7.30 p.m., Bell Lecture Theatre, Physics Building, QUB.
Free admission, including light refreshments. Free parking on QUB campus after 5.30 p.m. http://irishastro.org.uk/

4. Mayo Dark Sky Festival, 27-30 October. Congratulations to Ronan Newman of Galway Astronomy Club for arranging an excellent collection of speakers and topics at this event; and to Fiona Hopkins for looking after the arrangements and logistics in Newport; it was an excellent event, and well attended by both visiting amateur astronomers, and locals. Congrats also to Georgia McMillan for getting the Dark Sky Park initiative under way and seeing it through to completion. Thanks also to Stephen Kershaw of Ktec Telescopes who donated a telescope as the major prize for the raffle.
We had a dry weekend from Friday evening to Monday morning, and some Sun during the day, but unfortunately not enough clear sky at night to enable us to appreciate just how dark the skies are there.

10. Fly A Rocket: The European Space Agency is looking for students for its new "Fly a Rocket!" programme. ESA's Education Office is looking for twenty students to participate in an online course about rocketry. Following completion of the course, the students will have the opportunity to take part in a full launch campaign at the Andoya Space Center in Northern Norway, and to launch a rocket. The course is aimed at younger university students, and it is accepting applications from education, media, and management students, showing that careers in the space sector do not necessarily require a detailed technical or mathematical background. Learn more about the program here: http://www.esa.int/Education/
