2000 UVI stories

March 2: Polar Substorm - Last week, an interplanetary wind storm hit our planet with a gale of energetic particles from the Sun. During the storm, a strong gust of solar wind triggered aurora captured by the Ultraviolet Imager on NASA's Polar satellite.

1999 UVI stories

December 29: The Warp and Woof of a Geomagnetic Storm - Using a team of three satellites, scientists are studying what happens when a solar coronal mass ejection strikes the Earth. This story includes a new Quicktime animation of a coronal mass ejection and the aurora borealis.

October 22: Aurora Alert - A blast of solar wind from the sun on October 21 is creating strong geomagnetic storm conditions a day later.

August 17: Cassini & Polar Join Forces to Study Earth - A bit of interplanetary luck allowed two separate space missions take advantage of each other's instruments Tuesday evening for coordinated measurements of Earth's magnetosphere.

June 1: How do gusts in solar wind stir the aurora? - NASA Scientist studies data from 3 satellites to figure out what stirs up Earth's Northern Lights.

1998 UVI stories

Dec 8: Solar Wind blows some of Earth's atmosphere into space - The northern lights are more than beautiful; they are indicators of powerful storms strong enough to drive some of Earth's upper atmosphere right into space!

October 27: Seeing the invisible - New data on Earth's magnetosphere is slowly turning the invisible into the visible, revealing more about space weather.

October 16: Surprising gap in auroral oval puzzles scientists - Opening in the nightside aurora borealis may be linked to events in space.

May 28: Aurora Borealis acts up: Odd Auroral arc seen crossing the north pole, leaving scientists with a puzzle no model explains.

March 1: The best of UVI and the '98 eclipse: To help print publications (and anyone else) covering the Feb. 26, 1998, eclipse, we are posting some image guides.

February 23: Watching the Moon's shadow: While most eyes turn skyward to watch Thursday's solar eclipse (with the appropriate filters to protect your eyes) one satellite will look earthward to watch the moon's shadow race across the globe.

1997 UVI stories

December 31: Stormy Space Weather NASA/Marshall scientists were instrumental in following the eruption of two coronal mass ejections (CMEs) of material from the Sun. (from the 1997 Space Sciences Laboratory science highlights story)

December 9: Comet Rain debate continues Review of data indicates that the cause is noise.

December 9: Other views of small comets debate The following press releases were issued by the Universities of Iowa, Arizona, and Washington in connection with papers being presented Tuesday, Dec. 9, at the American Geophysical Union meeting in San Francisco.

November 7: Solar Flare may spark Earthly aurora this weekend UVI and its companion, the Visible Imager (VIS) will have the best view of the aurora borealis (northern lights), if it occurs, as they look down on Earth's arctic regions.

June 17: Hale-Bopp and UVI Watching comet Hale-Bopp through UVI

April 15: Aurora in the Sky with Diamonds - Scientists at NASA's Marshall Space Flight Center watched the Northern Lights in real-time with the Ultraviolet Imager Experiment aboard the POLAR spacecraft.

April 9: Here Comes the Sun... - Scientists at NASA's Marshall Space Flight Center will be watching the Earth's aurora in real-time with the Ultraviolet Imager Experiment aboard the POLAR spacecraft.

1996 UVI stories

December 31: All the Aurora, All the Time With UVI, the aurora borealis now can be seen in both day and night, year-round. (from the 1996 Space Sciences Laboratory science highlights story)

December 13: MSFC Earth-Sun Studies Featured at AGU - UVI, included in three sessions at AGU, extends the busy season by letting scientists see what happens during the day. Doing this has been a challenge because the atmosphere's ozone layer reflects solar ultraviolet light that blinds most sensors.

June 25: New Instrument Images Daytime Aurora: The Ultraviolet Imager (UVI) uses a specially designed camera to filter out all of the light except that emitted by the aurorae themselves.
