Abstract
In this note we propose that recently discovered radio pulsar J0250+5854 with 23.5 sec spin period is presently at the Hall attractor stage. This can explain low temperature and absence of magnetar-like activity of this source together with its spin period and period derivative. We present results of calculations of the evolution of this source in a simple model of magnetic field decay. The neutron star could start its evolution as a magnetar with initial field $\sim 10^{14}-10^{15}$ G for realistic range of parameter $Q$ describing crust imperfections. Future measurements of surface temperature and age of this neutron star might help to probe this hypothesis.
