N2 - The sunspot numbers and polar faculae are analyzed to demonstrate that the current solar activity is close to the Grand minimum. Notably protracted Cycle 23 is found to be similar to the cycles on the eve of the Dalton and Gleissberg–Gnevyshev minima. The polar faculae as proxy of the polar field replicate variations of the sunspot cycle amplitude over the last 100 years. The weak sunspot activity of Cycle 24 is assumed to result in the weak polar field.
