Narrative:
Shortly after takeoff the master warning light and chime went off and an engine low oil pressure warning was displayed. After several seconds the warning disappeared; only to reappear moments later. The captain (pilot monitoring) elected to divert to our planned takeoff alternate airport; and declared an emergency. The warning disappeared again and did not reappear for the remainder of the flight. After going through the QRH the captain decided not to shut down the engine; as it was then indicating within normal limits; although the oil pressure was fluctuating. I continued flying and he communicated with the dispatcher (to the best of my knowledge). After just 18 minutes aloft I landed the aircraft (overweight). I was asked to file this report in case we did not communicate our diversion with our dispatcher. To the best of my recollection the captain did contact the dispatcher. Our landing was at our takeoff alternate.
