For a regular immersion of schemes Z X and a cohomology theory of fs log schemes, we formulate the logarithmic Gysin sequence using the "logarithmic compactification" (BlZ X, E) instead of the open complement X-Z, where E is the exceptional divisor. We show that all A¹-invariant cohomology theories produced from motivic spectra and various non A¹-invariant cohomology theories like Nygaard completed prismatic cohomology admit logarithmic Gysin sequences.
