Spin-Scan Auroral Imaging (SAI)
Photo Gallery

Thumbnail	Name	Size	Brief Description
	DE-1 & DE-2 Stack	124 kB (600x747)	A pre-launch photo of the DE-1/DE-2 spacecraft stack before being covered by their fairings and mated with the Delta launch vehicle. DE-1 is on the bottom. One of the three SAI instruments is visible in the center of DE-1 with the several different sized circular openings.
	Final Assembly Stack on Delta	146 kB (747x940)	A pre-launch photo of the DE-1/DE-2 spacecraft stack as they are being covered by their fairings and mated with the Delta launch vehicle. DE-1 is on the bottom.
	Delta Launch	54 kB (600x755)	A launch photo of the Delta launch vehicle with the DE-1/DE-2 spacecraft aboard.
	DE-1 & DE-2 Orbiting	141 kB (410x414)	An artist's painting of the two Dynamics Explorer satellites in orbit over Earth.
	SAI Photometers	73 kB (950x589)	A pre-launch view of the three SAI photometers prior to spacecraft integration.
	Great March 89 Aurora	99 kB (1024x768)	An example of a very large auroral oval time sequence over the southern polar regions that occurred 13 Mar 89 (89/072). The upper panel of images run from 1649 to 1813 UT, at 12 minute intervals. The large image on the right is the 1737 UT image. The large image on the left is an example of a quiet auroral oval for comparison from an earlier time period with the same viewing geometry.
	Great March 89 Aurora Re-Mapped	68 kB (1024x768)	The left image is an extreamly large aurora that occurred 14 March 1989 at 0151 UT over the southern polar regions and the right image is a re-mapping of that image along magnetic field lines to the northern polar regions. This is a close approximation of what the auroral oval probably looked like if DE-1 had been over the northern hemisphere at this time.
	Theta Aurora	211 kB (1024x768)	A long, breath-taking sequence of images showing the growth and decay of a Theta Arc feature first seen with the DESAI. This image sequence occured 8 November 1981 (81/312) from 14:12 UT in the first image in the upper left panel until 17:02 UT in the lower right panel. Each image is separated by approximately 12 minutes.
	City Lights	60 kB (249x716)	Low altitude image with the bioluminance filter (482M) showing some city lights visible in Central America and the southern portions of North America along the Baja California region on 27 Sep 81 (81/270) at 4:50 UT.
	Aurora Oval	92 kB (1024x768)	A bright auroral oval as seen from directly over the north pole. This image was obtained 23 Nov 81 (81/327) at 10:48 UT.
	Aurora Oval (with coast lines)	66 kB (635x746)	Same as above, except this image includes a coastline map overlayed on the SAI image. It also has the Magnetic and Geographic North poles marked as M and N, respectively.
	Panoramic View	85 kB (1024x768)	A full 360° image (in 3 panels) showing the VUV photometer's field of view of the sky. The galactic plane is clearly visible crossing the right-hand panel. The image was obtained 21 Jan 86 (86/021) at 19:40 UT.
	DE Orbits	75 kB (936x640)	Dynamics Explorer 1 & 2 Orbital Configurations. Full Caption
	Geocorona	74 kB (763x983)	Polar and Equatorial Views of Geocorona and Air Bands. Full Caption
	Auroral Crown	148 kB (641x723)	The Auroral Crown. Full Caption
	Auroral Crowns	85 kB (780x838)	The Auroral Crowns.
	Substorm	39 kB (809x780)	Late Stage of an Auroral Substorm. Full Caption
	Spatial Distribution	109 kB (699x702)	The Spatial Distribution of Aurora. Full Caption
	Theta Aurora 2	54 kB (656x649)	Theta Aurora over Antarctica. Full Caption
	Dynamic Aurora	114 kB (1094x829)	The Dynamic Aurora. Full Caption
	Great Auroral Substorm	98 kB (808x1012)	A Great Auroral Substorm. Full Caption
	Small Comet	182 kB (1030x838)	A Small Comet. Full Caption
