Partial Solar Eclipse 2021
Join I-LOFAR and DIAS Dunsink Observatory to watch the partial solar eclipse live from two locations in Ireland.
The partial annular solar eclipse on 10 June 2021 will be visible from Ireland! In Dublin, the eclipse can be seen from 10:01 until 12:21, with maximum at 11:08. In Birr, Offaly it will be seen from 09:58 until 12:19, reaching a maximum at 11:06.
Join researchers at I-LOFAR in Birr Castle Demesne (Offaly) and DIAS Dunsink Observatory (Dublin) LIVE from 10:00 Irish time on Thursday 10 June. We have solar telescopes with cameras set up at both locations and will be live streaming a close up of the Sun so we can see the eclipse as it happens! We will be chatting with some of Irelandâ€™s leading solar physics researchers, Peter Gallagher and Aoife Ryan, to understand what we are looking at, what happens during a solar eclipse, and why it is important to study the Sun, our closest star.
This free event is open to all and will be live streamed online via YouTube, which includes an opportunity for attendees to comment and ask questions to the solar physics researchers.

To get ready for this eclipse, we chatted with some of the solar physics researchers at DIAS Astronomy and Astrophysics working with I-LOFAR to learn more about what will be happening…
What is an annular eclipse?
When the Sun, Moon, and Earth are exactly in align an eclipse will occur. From Earth the light of the Sun appears to be blacked out by the disc of the Moon. However the orbit of the Moon is not a perfect circle- at different times it is closer and further away. When the Moon is closer to the Earth it doesn’t block out all of the Sun’s disc and it looks like a bright ring around the dark disc of the Moon. This is called an annular eclipse.
How often do eclipses occur?
Eclipses occur 2-4 times a year. However most of these are not observable for us because they happen over oceans, which make up 2/3 of Earth’s surface. Most places on Earth will only see a total or annular eclipse once every few hundred years.
Why are eclipses interesting for research?
Solar eclipses are an invaluable tool for scientific research. When the Moon blocks out the Sun’s disc the outer layers of the Sun’s atmosphere, called the solar corona, are revealed. These are not normally visible as the lower layers of the Sun’s atmosphere are so bright. In addition, the conditions on Earth (such as temperature changes) can be monitored during the eclipse.
Why do we study the Sun?
The activity of the Sun, our closest star, can have an immense impact on our daily lives. The effects of large and violent explosions on the Sun can be observed at the Earthâ€™s magnetosphere, most noticeably as aurorae or disruptions to telecommunications and power grids. This demonstrates the importance and necessity of solar physics research, especially into the drivers of space weather.
This event is organised and hosted by DIAS Dunsink Observatory and I-LOFAR through the AstroLands programme, an initiative of Trinity College Dublin supported by Science Foundation Ireland and ESERO Ireland.
