Europe's Largest Gathering of Solar Scientists Descend on Trinity College Dublin
The solar researchers will discuss some of the biggest questions in modern astrophysics, such as how solar storms cause 'space weather' impacts here on Earth.
Over 240 solar scientists will gather today for the beginning of 'the premier conference in Europe' in all aspects relating to the physics of the Sun. The School of Physics at Trinity College Dublin will play host to the scientists, who are here to discuss and debate the latest discoveries relating to our nearest star at the 14th European Solar Physics Meeting.
Solar physics addresses some of the biggest scientific questions in modern day astrophysics and is a truly 'composite science', requiring expertise and knowledge in physics, mathematics, computer science and engineering (all of the STEM subjects in one field) to answer difficult questions. Combining exciting cutting-edge science with the most advanced technology available, such as ESA and NASA satellites and new generations of ground-based telescopes, researchers unravel the mysteries of how the Sun works by detecting dynamic activity in the Sun's atmosphere. That is extremely important because solar activity causes 'space weather' (solar storms).
ESPM-14 is poised to deliver the latest developments in our understanding. Dr Shaun Bloomfield, Senior Research Fellow in the School of Physics at Trinity College Dublin, is the chairperson of the local organizing committee. He said: "The ESPM conference series is a rare occasion for all of the disciplines in the European solar research community to come together and take stock of our current understanding of the Sun and the challenges that we face."
Ongoing research in Trinity College Dublin's Solar Physics and Space Weather Research Group, led by Prof Peter Gallagher, has a particular emphasis in the study of space weather, which appears when conditions change in near-Earth space due to solar flares and energetic eruptions coming from the Sun. This thriving research group specializes in predicting the occurrence of solar activity and the arrival of solar storms at Earth.
"The Sun has the power to influence the near-Earth environment on a daily basis, causing major disruptions to Earth's protective magnetic shield. Adverse space weather can create things as beautiful as the Northern lights, but it can also impact our day-to-day lives in the form of satellite communication failures and radio blackouts," said Dr Shaun Bloomfield.

Public Lecture at TCD: "Seeing stars: science and education with big telescopes"
We are pleased to announce that Professor Paul Roche (University of South Wales) will give a public lecture on the evening of Thursday August 14th in the Joly Lecture Theatre in the Hamilton Building of Trinity College Dublin (see here for location of the venue).
Astronomy is a science that asks (and sometime answers!) the biggest questions in the Universe. Modern astronomers benefit from access to some of the most advanced technology on the planet, capable of detecting the gases in the atmospheres of distant worlds that might one day reveal the presence of life beyond our solar system. Combining exciting science with state-of-the-art technology like the massive European Southern Observatory facilities allows researchers to unravel the mysteries of the Universe - but also provides educators with amazing opportunities to inspire the next generation of scientists.
This talk will look at the development of big telescopes, and how schools are engaging with real science, and helping to make real discoveries.
The event is free and open to the public and doors open at 7:00 pm. The venue has limited seating so if you are planning to attend the public lecture we ask you to please register online using this form.

Trinity's New Observatory in Birr to Illuminate the Sun-Earth Connection
The Rosse Solar-Terrestrial Observatory - a Trinity College Dublin School of Physics teaching and research facility devoted to studying the Sun and its effects on Earth - will be officially opened with a ceremony at Birr Castle Demesne, Co. Offaly, on Saturday June 28th.
The Sun is an enormous ball of hot gas, which keeps our planet hot enough for life to flourish. From time to time though, huge clouds of hot solar gas can be flung into space at hundreds of thousands of kilometres an hour. These 'solar storms' can endanger astronauts and cause problems for telecommunications and navigation systems here on Earth. Scientists will use the observatory and its set of scientific instruments to work out when solar storms erupt from the Sun and when they hit the Earth's upper atmosphere and magnetic field. Scientists at Trinity have developed the observatory at Birr Castle in the midlands of Ireland to monitor the effervescent Sun's nearly unpredictable outbursts.
Director of the Rosse Solar-Terrestrial Observatory and Associate Professor in Physics at Trinity, Peter Gallagher, said: "We are delighted to reignite scientific research at Birr and to honour one of Ireland's greatest innovators of the 1800s, the 3rd Earl of Rosse, by naming the observatory for him."
Trinity has established links with Birr that stretch back over a century and a half. Indeed, the 3rd Earl was Chancellor in 1862-1867, the 4th Earl was Chancellor in 1885-1908 and the 6th Earl was Pro-Chancellor in 1949-1979.
The observatory will enable researchers to study the Sun and its effects on the Earth like no other facility in Ireland. A set of antennae will constantly monitor solar activity, while another antenna will monitor solar effects on a layer of the Earth's upper atmosphere called the 'ionosphere'. Ionospheric disturbances can cause drop-outs in high-frequency communications with aircraft.
An additional instrument, called a magnetometer, which is operated jointly with the Geophysics Section of the Dublin Institute for Advanced Studies, will continuously monitor disturbances in the Earth's magnetic field. These 'geomagnetic storms' can cause deflections in compasses and surges in electricity power grids.
Professor Gallagher added: "A facility like this will also enable Irish students to gain valuable hands on skills in programming, electronics, antennas, and cutting-edge scientific research at a working observatory. Physics graduates are in great demand in high-tech companies and end up working in a wide range of sectors including IT, finance, engineering, education, which are all areas of particular importance to the development of the smart economy in Ireland."

TCD Researcher Dr. Eamon Scullion and Colleagues Unlock Secrets of Solar Rain
Just like on Earth, the Sun has spells of bad weather, with high winds and showers of rain. But unlike the all-too-frequent storms of the UK and Ireland, rain on the Sun is made of electrically charged gas (plasma) and falls at around 200,000 kilometres an hour from the outer solar atmosphere, the corona, to the Sun's surface. And the thousands of droplets that make up a 'coronal rain' shower are themselves each as big as Ireland.
Now a team of solar physicists, led by Dr Eamon Scullion of Trinity College Dublin, have pieced together an explanation for this intriguing phenomenon, with imagery that shows a 'waterfall' in the atmosphere of the Sun. Dr Scullion will present their work at the National Astronomy Meeting (NAM 2014) in Portsmouth on Tuesday 24 June 2014.
The coronal rain is much clearer in a movie, and can be seen in the latter half of the CRISP movie available for download here. The rain appears to flow from the lower-right to the upper-left of the field of view.

TCD researchers use NASA Telescopes to coordinate best-ever flare observations
On 29 March 2014, an international team of scientists, including Dr. Paul Higgins (an Irish Research Council Research Fellow in the Trinity College Dublin Astrophysics Research Group), obtained the most detailed observations to date of an X-class solar flare. The huge solar eruption was recorded simultaneously from multiple telescopes on the ground and in space. The event is one of the best observed flares using modern instrumentation. The team's success was helped by Dr. Higgins, a flare prediction expert, who assisted the team in New Mexico by making an accurate forecast of the event and initiating a 'Major Flare Watch' hours beforehand, putting observatories around the world on high-alert.
A discussion of the event is set to air on NASA TV today, May 8th at 19:30 Irish Time.

Researchers at TCD and Zooniverse launch Sunspotters website
A new project lead by a team of researchers at ARG and Zooniverse has launched! Sunspotter is a new citizen science project which aims to give anyone with an interest in science the opportunity to get involved in frontier space research.
Guests of the website will be given the opportunity to classify the complexity of regions of strong magnetic field, called sunspots, which are located on the surface of the Sun. Complex sunspots are believed to be more likely to produce enormous explosions known as solar storms. These storms can have a strong effect on life on Earth, as they can be damaging to our power grids, GPS and communications satellites, and even astronauts during spacewalks. Therefore by helping to spot complex active regions, users can help scientists predict and prepare for these potentially destructive events.

- 17 Oct 2013: Trinity Researchers Tune in to the Radio Sun
The Sun gives light and heat that makes life possible on Earth. It can, however, have more sinister effects, sometimes unleashing huge eruptions of hot gas, called solar storms, which carry billions of tons of matter travelling at millions of kilometres an hour in Earth's direction. These storms can be accompanied by solar radio bursts, which can cause damaging effects on many of the technologies that we rely on in our everyday lives.
''Radio bursts from solar storms can have adverse effects on both satellite and terrestrial communications. In fact, mobile phone networks can experience increased dropped-calls during periods of increased solar activity,'' said Eoin Carley, Irish Research Council PhD student at the School of Physics, Trinity College Dublin and first author on a recent paper on this topic in Nature Physics.
Despite decades of study, the link between solar storms and solar radio bursts has remained unclear. This led Professor Peter Gallagher,a solar physicist at Trinity's School of Physics, to establish a radio observatory at Birr Castle in the midlands of Ireland to monitor solar radio bursts.
''What we have found is fascinating − a real insight into how solar radio bursts are created'', said Professor Gallagher. ''Using antennas at Trinity's Rosse Observatory in Birr Castle together with images from NASA's STEREO and Solar Dynamics Observatory spacecraft, we have identified a missing link between solar storms and radio bursts.''
The findings, which were published online this week in Nature Physics, show that solar storms create huge shock waves that race through the solar atmosphere at millions of kilometres per hours. As they do, they can accelerate electrons to huge energies, which then produce radio waves.
''Our results not only give an insight into the fundamental physics of explosions on the Sun, but enable us to better understand how the Sun affects the Earth and potentially its impacts on our daily lives'' according to Carley.
The full paper can be found here.
This research has been supported by the Irish Research Council which funds research and scholarship relevant to all aspects of social, cultural and economic development in Ireland. The authors would like to thank NASA for their open-access data policy.

- 29 April 2010: Summer Internship: "Development of A Smart Phone Application for Scientific Data Access" The Solar Physics Group needs to develop a smart phone app to access data from SolarMonitor.org. The initial target platform will be the iPhone, with the aim to allow subsequent support for Symbian, Blackberry and Android. The developer will need to be very aware of what the solar physics users want from the app. This project will result in an intuitive application for mobile devices, which will allow anyone to easily ascertain both the solar surface and space weather conditions in near realtime and on any day since 1996. A prime aim of this short project is to produce usable results. The results should be open source if possible, perhaps as a mobile web app. A student with expertise in developing applications for mobile devices will be hired for three months from June through August 2010. The student will be located in the Lloyd Instutute CAGlab, but will need to maintain very good communication with the Solar Physics Group. Please contact Dr. Peter Gallagher (firstname.lastname@example.org) for further details. This internship is supported by the Innovation Bursaries 2010 scheme.

- 14 September 2009: The launch of the second in the series of PROBA satellites has been confirmed for the beginning of November this year. PROBA2 will carry two instruments designed to study the Sun: SWAP and LYRA. These instruments will be used, not only acquire cutting edge observations, but also to validate new spacecraft technology. While the principle investigators of both instruments are based at the Royal Observatory in Belgium, the Astrophysics Research Group at Trinity College Dublin have played a significant role as co-investigators. Their contribution to the calibration of SWAP and the preparation of user-friendly software for both instruments has been vital to the pre-launch preparation processes. The satellite, one of
the most compact ever built by ESA, has recently arrived at Plesetsk Cosmodrome in northern Russia, where it is being prepared for launch. The launch, which has been delayed in the past to allow for Russian launches is now set for 01:50 am (corrected to Irish local time) with separation occurring at 04:50am. For more information, tune into Ireland AM on Wednesday 16th September at 9.15am to hear Dr. Peter Gallagher, PI of the TCD solar physics group discuss the details of the mission.
