We attempted to detect the Earth-Moon libration clouds around L4 with a cooled CCD camera at Mauna Kea (4200m), Hawaii, on November 17 and 18, 1999. No significant enhancement of brightness larger than 1.5Sio© was found around L4. It seems that the brightness of the libration clouds in 1999, if it existed, would be fainter than that reported previously by Kordylewski  and Roach .
