This may be a once in a lifetime celestial event for Earthlings to witness. A sun-grazing comet, McNaught, is visible to the naked eye in broad daylight! If you have clear skies, you should step outside today and try to observe the comet.
SOHO also “sees” the comet, but it’s so bright in the sky it badly blooms the image.
