The comet reached minimum elongation on 13 March, on 25°. [4] It reached its peak brightness in April. Jacobson spotted the comet with naked eye on April 18. David H. Levy reported that the comet had an apparent magnitude of 4.7 with the naked eye on April 24. In the end of April the tail of the comet was reported to be up to 2–3 degrees long.
The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek.

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [16] appearing every 72–80 years, [17] though with the majority of recorded apparations (25 of 30) occurring after 75–77 years.
Soon after the first orbital elements could be calculated, it was suggested that the comet would become "a bright object, that could be observed with unaided eye."It was found to combine three favorable characteristics that made it an exceptional comet for observation: a short perihelion distance, a short distance from Earth, and high intrinsic brightness.
