We present new CCD observations of nine Near-Earth
Asteroids carried out between February, 1999 and July, 2000.
The bulk of the data was acquired through an RC filter, while
the minor planet 11 405 was observed without filter.
We could determine synodic periods and amplitudes for 5
asteroids,
699: 
, 
;
1866: 
, 
;
1999 JD6: 
, 
;
2000 GK137: 
, 
;
2000 NM: 
, 
.
Based on observations taken at different phases, we could
infer a phase parameter m of 
for 1865 Cerberus.
An epoch-method yielded a sidereal period
of 
for this object with retrograde rotation.
The remaining 3 objects have only partial coverage, thus
no firm conclusion on their synodic period is possible.
Key words: solar system: general / minor planets, asteroids
