abstract
The "standard candle method" for Type II plateau supernovae produces a Hubble diagram with a dispersion of 0.3 mag, which implies that this technique can produce distances with a precision of 15%. Using four nearby supernovae with Cepheid distances I find Ho(V)=75+/-7, and Ho(I)=65+/-12.

Sub-luminous Type IIP SN 2024abfl as a result of a significantly low energy Fe-core collapse
SN 2024abfl is a sub-luminous Type IIP event from a compact progenitor exploding with energy at most 0.05 foe and nickel mass 0.003 solar masses.
