    "Sunrise" is a balloon-borne solar observatory that was launched for it's second flight in June 2013 from the Esrange Space Center near Kiruna, northern Sweden. The movie is a compressed recap of the final launch preparations of this exciting scientific experiment. The time-lapse sequences were captured by a colleague and myself during our involvement in the on-site launch preparations.

      Established by the bequest of Jane Arctowska in honor of her husband, Henryk Arctowski. Presented since 1969 to honor outstanding contributions to the study of solar physics and solar-terrestrial relationships. For elucidating fundamental issues in the physics of the solar atmosphere and solar wind, including revealing the “Solar Flare Myth”, discovering bi-directional solar-electron streaming and, in the last decade, finding reconnection events in the solar wind

        • Hazel Bain: The Sun - A Star in our Own Backyard

          Hazel Bain presents a public talk at UC Berkeley on March 17th, 2012, as part of the Science@Cal Lecture Series described at http://scienceatcal.berkeley.edu/lectures The stars in the night sky have always been a source of intrigue and wonder. With our very own star at the center of our solar system, the Sun offers us a unique opportunity to study the inner workings of these giant balls of plasma. Starting at the core, I will discuss the processes occurring at the different layers of the Sun: From sunspots observed in the photosphere, which vary characteristically with the solar cycle, to explosive flares and coronal mass ejections, which release huge amounts of energy into the corona. Finally I will talk about the effect these eruptive events have on the Earth's atmosphere, and how the particles accelerated at the Sun produce the displays of lights known as the Aurora Borealis and the Aurora Australis. Dr. Bain is originally from Scotland, where she obtained her undergraduate degree in Physics and Astronomy from the University of Glasgow. She stayed on in Glasgow to do a PhD in solar physics working with Dr. Lyndsay Fletcher. Upon completing her PhD she moved across "the pond" to start a postdoc with the RHESSI solar physics group at the Space Sciences Laboratory here at UC Berkeley. Her main area of research involves studying solar eruptive events such as flares, jets and coronal mass ejections, using both space and ground based instruments such as NASA's Reuven Ramaty High Energy Spectroscopic Solar Imager (RHESSI) and the Solar Dynamics Observatory (SDO) spacecraft, and the Nancay and Nobeyama Radioheliograph radio interferometers.

          • European Solar Telescope (EST)

            The European Solar Telescope (EST) is the future project for European ground-based solar astronomy. It is the main project for EAST (European Association for Solar Telescopes), an association with 15 member institutions from 15 European countries. The EST's main mission is to observe the Sun. Understanding it is crucial for many reasons: 1. There is a fundamental link between the earth and the Sun. The Sun is of primary importance because it maintains life on earth. Any change in conditions in the Sun could have dramatic consequences for us. Large amounts of energy can be transferred into the plasma, from where it is stored in the magnetic fields, in very small periods, between seconds and minutes. These transfers can accelerate the plasma to speeds of within a fraction of the speed of light and, if this accelerated plasma (in the form of an ejection of coronal mass) reaches the earth's magnetopause, it can give rise to fascinating events (auroras) and phenomena that are potentially dangerous for our environment (damage to satellites, overloading energy lines, excessive radiation exposure for space crews or the International Space Station etc). This means that it is essential for us to study all of these processes so that we can predict them. 2. The Sun is a fundamental physics laboratory (the interaction between the plasma and the magnetic field can only be studied in the Sun's extreme physical conditions). 3. The Sun is a fundamental model for understanding the rest of the Universe (all of the stars are suns). The EST will look at the fundamental solar processes at their tiniest scales, allowing us to analyse physical phenomena in the greatest possible detail.
