sd
sc
sa
so
sba

Explanation:

The Hubble sequence classifies spiral galaxies by bulge size and arm tightness: Sa has large bulges/tight arms, Sc has smaller bulges/looser arms, Sd has very small bulges/very loose arms. S0 is lenticular (no arms), SB is barred. The galaxy here has a small bulge and wide loose arms, matching Sc.

Sc
