Query: Anomaly in the HTSC system (BiPb)2Sr2Ca2Cu3O10-{\delta} at the
  temperature 203.7K   Broadening of the electron paramagnetic resonance (EPR) line of the
paramagnetic probe decorated on the superconducting system surface was detected
at the temperature T>Tc. The source of the anomaly and the conditions of its
emergence were revealed. The analysis of the experimental results with taking
into account the literature data serves as the basis to consider that the
observed broadening of the EPR line of the paramagnetic probe at 203.7K
resulted from the transition of the system under study into the superconducting
state.
