"In the vicinity of a solar flare associated with a CME, most matter is moving away from the solar surface, but the tadpoles move downward at initial speeds between 30 and 600 kilometers per second (about 19 to 373 miles/sec.), something you don't expect," said Dr. David McKenzie of Montana State University - Bozeman, who has observed these features many times before at lower resolution with the Soft X-ray Telescope on board the Japanese Yohkoh spacecraft.
"Imagine a hot-air balloon lifting off the ground and stretching elastic tethers placed over its top," said McKenzie.

If all goes as planned, the telescopes will be launched between 8:30 and 9:30 a.m. Montana time on NASA's Solar Dynamics Observatory, said David McKenzie, an associate research professor at MSU.
McKenzie and Piet Martens, an MSU research professor, will be in Florida for the launch, but the public is invited to watch a live feed on the big screen in MSU's Studio 1080, McKenzie said.

If the flight is delayed, the viewing event will be rescheduled, McKenzie said. Updates will be available on the Montana Space Grant Consortium's Web page at http://spacegrant.montana.edu and on the MSU Solar Physics Group's Web page at http://solar.physics.montana.edu McKenzie and Martens helped design the telescopes with partners at the Lockheed Martin Solar and Astrophysics Laboratory and the Harvard-Smithsonian Center for Astrophysics, McKenzie said.

"It (the upcoming launch) is the culmination of a long wait," McKenzie said. McKenzie said the UV telescopes -- together called an Atmospheric Imaging Assembly, or AIA -- will spend at least three years collecting ultraviolet images from the sun's atmosphere. Each of the four telescopes will collect ultraviolet rays at two different wavelengths. Together, they will yield 1,000 gigabytes of information every day. "That's more than anyone can look at in a lifetime," McKenzie said. The information will be transmitted to computers in the Midwest and sent to MSU, Stanford University and Lockheed Martin for analysis, McKenzie said. He added that Martens has a grant, jointly with the Harvard-Smithsonian Astrophysical Observatory, to develop computer software for automatically recognizing features in the solar images returned by AIA. The main goal of the UV telescopes is to help scientists understand the physics behind the activity on the sun's corona, which drives space weather, McKenzie said. The ultimate goal is to use this information to develop advanced forecasting tools in NASA's Living With a Star program. The Atmospheric Imaging Assembly is one of three instrument packages that will be launched on the Solar Dynamics Observatory, McKenzie added. Ultraviolet rays cause sunburns, but they also affect the chemistry of the Earth's atmosphere, McKenzie said. UV rays relate to global warming, ozone layers and greenhouse effect. He added that the sun is a very active star. "We need to understand how it's producing these activities that affect us," McKenzie said. The Solar Dynamics Observatory is the first satellite to be launched in NASA's Living with a Star program, McKenzie said.
