(CNN/NASA) - You may want to stay up late Friday night to watch the sky.
NASA is expecting a never-before-seen meteor shower this weekend. The agency is calling it the May Camelopardalid meteor shower.
Forecasters say it could rival even the Perseid meteor shower. Video above this story is time-lapse footage of that meteor shower last August.
But be prepared, NASA says the new meteor shower could put on a spectacular show or it could fizzle; scientists aren't sure.
"Some forecasters have predicted a meteor storm of more than 200 meteors per hour," said Bill Cooke, of NASA's Meteoroid Environment Office. "We have no idea what the comet was doing in the 1800s. The parent comet doesn't appear to be very active now, so there could be a great show, or there could be little activity."
It's expected to peak after midnight Saturday, between 2 and 4 a.m. ET.
