![]() ![]() Solar Wind The ever-present expansion of the Sun’s hot outer atmosphere into the solar system, which carries space weather within it. Photos taken by the Mars Reconnaissance Orbiter reveal the surface of Mars has flowing liquid Source: NASA/Getty Images. NASA News: Here Are Some of the Biggest Space Discoveries of 2015. Measured in units of nano-Tesla (for the strength of the field) or in degrees (direction of the field). Below are some of the biggest discoveries of the year to sum up just how brilliant space exploration has been throughout 2015. Magnetogram The variation, minute by minute, of the strength and direction of the Earth’s magnetic field. High Speed Stream A fast moving stream of solar wind, responsible for magnetic storms. Glossary BGS The British Geological Survey is one of the Natural Environment Research Council's Research Centres.Ĭoronal Hole A region in the Sun’s outer atmosphere (corona) where hot material can flow unrestrained by its magnetic fields out into space.

Keep an eye on current geomagnetic conditions using the links below and if things start to kick off again and the sky is clear where you are (particularly at high latitudes), maybe go outside and have a look to the North. This is a bit further north on the solar disc than the one currently bathing the Earth, but could still cause appreciable disturbance, especially when the heightened activity levels of the past week are taken into account. The effects of a second coronal hole are expected to make themselves known by 13 September. The Twins Study helps the agency begin to grapple with these potentially difficult and complex issues, including how to archive this type of genetic information, mine it responsibly, and develop and implement policies. The coronal hole high-speed stream is likely to affect the Earth's magnetic field for the next 24-48 hours. (NASA) NASA is examining how to handle omics data and privacy concerns from the perspective of medical ethics. While the IMF has since retreated northwards, further geomagnetic storms and resulting auroral displays are possible, particularly if the IMF turns southward again. This morning, due to the influence of a high-speed solar wind stream from a large coronal hole, geomagnetic storm conditions were observed when the interplanetary magnetic field (IMF) within the solar wind slipped strongly southwards.
