  • Comet Machholz 96P
    Comet Machholz was first discovered in 1986 then identified as a returning periodic comet in 1996 hence it's 96P designation.  It has a period of 5.29 years but it's highly inclined orbit means that it usually approached and recedes from the Sun along our twilight glow remaining invisible.  On this visit, it cis currently very bright but can only be observed by orbiting solar observatories.  https://soho.nascom.nasa.gov/data/realtime/c3/512/
