(From Spaceweather) -- The US Navy's first attempt to hit malfunctioning spy satellite USA 193 with a missile could come on Wednesday night during the lunar eclipse. This is based on an air traffic advisory warning pilots to steer clear of a patch of Pacific Ocean near Hawaii just when USA 193 is due to pass overhead. Until the satellite is shot down, it remains visible to casual sky watchers during evening passes over US and Canadian towns and cities; experienced observers say the decaying satellite is sometimes as bright as the stars of Orion, making it an easy target for unaided eyes and off-the-shelf digital cameras. Details, photos and more information are available at http://spaceweather.com
So if you are out looking at the eclipse Wednesday night and a gentle rain srarts falling, it could well be Hydrazine.
quote:
Hydrazine is the chemical compound with the empirical chemical formula N2H4. Its formula can also be written as (NH2)2. It is widely used in chemical synthesis and is a component in some rocket fuels. With an ammonia-like odor, hydrazine has a liquid range and density similar to those of water. (...)
Hydrazine is highly toxic and dangerously unstable, especially in the anhydrous form. Symptoms of acute exposure to high levels of hydrazine in humans may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, coma, and it can also damage the liver, kidneys, and central nervous system. The liquid is corrosive and may produce dermatitis from skin contact in humans and animals. Effects to the lungs, liver, spleen, and thyroid have been reported in animals chronically exposed to hydrazine via inhalation. Increased incidences of lung, nasal cavity, and liver tumors have been observed in rodents exposed to hydrazine

CBC Newsworld had the story this morning, along with an animated short showing exactly how the satellite would be shot down, and that a second effort would be made if the first effort failed. I don't recall anyone saying the satellite would be visible to the naked eye.
