Apart from regular monitoring by ASM , the compact object SS 433 was observed with RXTE several times last two/three years .
We present the first analysis of these observations .
We also include the results of the recent exciting TOO campaign made during donour inferior ( orbital phase \phi = 0 ) and superior ( \phi = 0.5 ) conjunctions which took place on Oct. 2nd , 2003 , and on March 13th , 2004 respectively , when the jet itself was directly pointing towards us ( i.e. , precessional phase \psi \sim 0 ) .
Generally , we found that two distinct lines fit the spectra taken on all these days .
We present some of the light-curves and the X-ray spectra , and show that the Doppler shifts of the emitted lines roughly match those predicted by the kinematic model for the jets .
We find that the line with a higher energy can be best identified with a FeXXVI Ly- \alpha transition while the line with lower energy can be identified with a FeXXV ( 1s2p - 1s ^ { 2 } ) transition .
We observe that the X-ray flux on March 13th , 2004 ( when the base of the jet is exposed ) is more than twice compared to that on Oct. 2nd , 2003 ( when the base is covered by the companion ) .
We find the flux to continue to remain high at least till another orbital period .
We believe that this is because SS 433 was undergoing a weak flaring activity during the recent observation .
