Island residents are being urged by Maria Mitchell Association director of astronomy Vladimir Strelnitski to keep their eyes open for meteorites around Surfside and the south shore in the coming days following an unconfirmed sighting of a fireball blazing across the early-morning sky Friday, Feb. 20 at 4:30 a.m. Terry Galschneider was up early watching television when she said a dramatic orange fireball "lit up the sky" for five seconds. She said the fireball was too large and bright to have been a shooting star or a helicopter. Her full description to Strelnitski left him to "not exclude that it fell in the ocean, but maybe even on land."
