Preliminary Nucleus Size Estimate for #Kreutz Sungrazer C/2026 A1 (MAPS): https://iopscience.iop.org/article/10.3847/2515-5172/ae5220 -> "JWST imagery of the approaching Kreutz sungrazer C/2026 A1 (MAPS) appears sufficient to distinguish the comet’s nucleus from the surrounding dust. Coma model fitting indicates the morphology is compatible with a ∼0.4 km diameter nucleus—likely larger than those of the minor Kreutz fragments routinely discovered with coronagraphs, and comparable to or slightly smaller than that of C/2011 W3 (Lovejoy). However, since C/2026 A1 is the only Kreutz sungrazer whose nucleus has been directly observed, these comparisons should be treated with caution" -> https://groups.io/g/comets-ml/message/35035 / https://scicomm.xyz/@qicheng@cometary.org/116245251072721081
