Results of long time observations of the pulsar B0950+08 are given. These observations were carried out at the LPA radiotelescope at the frequency of 111 MHz from January of 2016 to May of 2019 (450 days). A strong variability in emission ofthis pulsar has been detected with changes of signal to noise ratios hundreds of times. In addition to the main pulse (MP)and interpulse (IP), this pulsar has “the bridge” and “the precursor” (Pr) located between MP and IP [1]. We detected theunusual IP and Pr radiation on August 1, 2017. On the base of strong 65 interpulses we found the correlations betweenenergies of IP and Pr and between the phase of IP and the distance Pr-IP. It is shown that the observed peculiarities ofthis pulsar can be explained in the frame of the aligned rotator model.
