Optical observations of the Phoenicid meteor shower were made in North Carolina, USA, with seven video cameras and two digital cameras over a period of about 5 hr between 22:30 UT on 2014 December 1 and 04:00 UT on December 2. Activity of the Phoenicids was confirmed during this period, including the predicted maximum around 00 h UT on December 2. The activity level was not high, considering that 29 Phoenicid meteors and 109 non-Phoenicid meteors were detected. A gentle peak in the activity was recognized between 01:00 UT and 03:00 UT on December 2. The compact radiant of the Phoenicids agreed well with what was predicted. A comparison of the observed and predicted peak times, radiant position, bright meteors' dominance, and radiants' spread revealed that the observed meteors originated from the dust trails formed by comet 289P/Blanpain at the perihelion passage in the early 20th century. This indicates that the parent body of the Phoenicids, comet 289P/Blanpain, was still active as a comet in the early 20th century and provided meteoroids, although its activity level was significantly weaker than that at the beginning of the 19th century.
