In one week, Kreutz sungrazer C/2026 A1 (MAPS) will reach perihelion just 0.23 solar radii above the Sun's surface. Whether anything of it still exists by then remains to be seen. However, even if its nucleus fully disintegrates right now, the remnant will still rapidly brighten in the final hours before perihelion as intense solar heating turns the dust into a trail of glowing gas likely peaking in integrated brightness at around magnitude −2 about 10 hours before perihelion (Apr 4 ~04 UT). Solar coronagraphs will provide a near-realtime view either way; here's a diagram of the trajectory through the SOHO/LASCO and GOES-19/CCOR-1 fields.
