1  KOBAYASHI 2023A found Parker-type bounds on magnetic monopoles with arbitrary magnetic charge based on the survival of galactic, seed, and primordial magnetic fields. Bounds are between $10^{-21}$ and $10^{-5}$ cm${}^{-2}$sr${}^{-1}$s${}^{-1}$ for masses between $10^{4}$ and $10^{18}$ GeV. Reported bound is the most stringent one.
2  Catalysis of nucleon decay.
3  ADAMS 1993 limit based on ``survival and growth of a small galactic seed field'' is $10^{-16}$ ($\mathit m/10^{17}$ GeV) cm${}^{-2}~$s${}^{-1}~$sr${}^{-1}$. Above $10^{17}$ GeV, limit $10^{-16}$ ($10^{17}$ GeV/$\mathit m$) cm${}^{-2}~$s${}^{-1}~$sr${}^{-1}$ (from requirement that monopole density does not overclose the universe) is more stringent.
4  Re-evaluates PARKER 1970 limit for GUT monopoles.
