The Great January comet of 1910 or Great Daylight comet was a Great comet that in January 1910 upstaged the much-anticipated appearance of Halley's Comet in May of the same year. It was already visible to the naked eye when it was first noticed, and many people independently 'discovered' the comet. At its brightest, it was brighter than the planet Venus.
When Halley's Comet returned again in 1986, many older people's accounts of having seen it in 1910 clearly referred instead to the Great Daylight Comet.
