  We prove Moderate Deviation estimates for nodal lengths of random spherical
harmonics both on the whole sphere and on shrinking spherical domains. Central
Limit Theorems for the latter were recently established in Marinucci, Rossi and
Wigman (2020) and Todino (2020) respectively. Our proofs are based on the
combination of a Moderate Deviation Principle by Schulte and Th\"ale (2016) for
sequences of random variables living in a fixed Wiener chaos with a well-known
result based on the concept of exponential equivalence.
