Bright object in eastern sky was an ASTEROID?

For anyone who saw a bright object in the eastern sky(low on horizon) for the last 2 weeks it's gone now, my best estimate is that it was an asteroid, possibly 2012 TC4, but as of today i cannot see it, last night we had cloud cover so i'm not sure if it was visible, i did see it thursday night. I tried the internet but got Jupiter as the search results, this object had the brightness of an airplane landing light. I'm in Central California near the Sierra Nevada Mountains, anybody else observe this object?
