    Hi all,
    
    	These two satellites seem to have an interesting behaviour which should
    request further  observations.
    
    	ETS-6 :
    	for more than 4 years, the period has been decreasing but my last
    observations seem to show an slightly increasing period :
    
    	Date		Period	Std deviation
    	29-06-02	8.852		0.002
    	17-07-02	9.2		0.2
    	26-07-02	9.0		0.2
    	29-07-02	9.12		0.3
    	01-08-02	9.08		0.4
    	13-08-02	9.16		0.1
    	22-08-02	9.22		0.2
    	31-08-02	9.29		0.2
    	01-09-02	9.30		0.3
    
    	RADUGA 27
    	the same for this sat, but this fact is more usual :
    
    	Date		Period	Std deviation
    	01-06-02	56.58		0.02
    	17-07-02	54.77		0.5
    	27-07-02	55.00		0.12
    	22-08-02	56.99		0.05
    	30-08-02	57.85		0.1
    	01-09-02	58.08		0.2
    
    	Michel
