Passing mid-level cumulus
This image is a shorter exposure version of my October 4 posting. It shows the planet Jupiter (bright object just above the roof) located in the eastern sky just SE of the zodiac constellation Aries as seen from Brentwood Drive NE in Cedar Rapids, Iowa around 9:45 PM, Monday October 3, 2011. The exposure settings for this shot was: 20 seconds at f/3.5, 800 ISO and an 18mm focal length. Jupiter held an apparent magnitude of -2.86. The planet is the fourth-brightest object in our skies.
Iowa State University meteorology student and storm chaser Sam Schreier walks hurriedly back to his vehicle while keeping an eye on a developing wall cloud (upper right) as it prepares to cross 210th Street a couple miles west of Ute, Iowa around 7:10 PM, Saturday, April 9, 2011. Note the rain shaft in the distant background. In about five minutes the wall cloud would drop a tornado, eventually growing in strength to an EF3, and would significantly damage the town of Mapleton about 15 minutes later. Shortly after this photo was taken our chase teams jumped back into our two vehicles and headed north, staying just outside the storm's SE flank but coming no closer than five miles of Mapleton, where we had actually driven through the town from the west about a half hour earlier. This view looks southwest.
A dark gray bank of cumulus clouds in the sky contrasts sharply with the vibrant autumn color and sunshine on the ground as seen from Bowman Woods Park in Cedar Rapids, Iowa around 4:25 PM, Friday, October 14, 2011. The clouds were moving in an ESE direction. This view looks northeast.
A tornado churns the ground northwest of the town of Arthur (city lights) in western Iowa around 8:28 PM, Saturday, April 9, 2011. The track of the storm was to the northeast, between the towns of Ida Grove and Arthur. This view, a video frame capture, looks NNW from along County Highway M31, about one mile south of town. Our two-vehicle chase team was stopped on the road after having followed the twister, which minutes earlier had a wedge shape. The brightness of this image was made possible by a flash of lightning.
The planet Jupiter (center) withstood the bright onslaught of a full moon as seen here looking east from Bowman Woods Park in Cedar Rapids, Iowa around 10:12 PM, Tuesday, October 11, 2011. The apparent magnitude -2.88 Jupiter is in actuality 41 times larger than the moon, but is also about 460 million miles farther away. The 2.06 magnitude variable star Algol ("The Demon Star"), in the constellation Perseus, is seen at upper left. Clear skies of eastern Iowa were a contrast to the rainy skies in western Iowa at this hour and mild conditions prevailed (58 degrees F). The silhouetted tree in the foreground at left is an European Larch. This image is a composite of the background sky and the moon. The background was an 18-second exposure at f/6.3, 200 ISO and an 18mm focal length. The moon, 1/2,000-second exposure at f/5.6, 640 ISO and a 200mm focal length.
