A RARE astronomical phenomenon will be visible across Warwickshire tonight (Wednesday), as the earth, moon and sun align for a solar eclipse. A solar eclipse is a momentary alignment that occurs when the moon passes in front of the sun and blocks its light, casting a small shadow on Earth. The advice for those wanting to view the eclipse is to never look directly at the sun without special eclipse glasses. Perseid meteor showersLater on tonight and tomorrow (Wednesday and Thursday), there will be the peak of the Perseid meteor shower will be visible tonight and tomorrow (August 12 to 13), when Earth passes through the debris left by comet Swift-Tuttle in its orbit. The conditions should be ideal for meteor watching, as the night is forecast for dark, moonless skies thanks to the eclipse.
