177P was originally discovered by E.E. Barnard using a 16cm refractor on 24 June 1889 and observed for about 6 weeks. Orbital solutions with the few positions available indicated that it had an intermediate period, likely to be in the range 128 -145 years and so would be due back in the Sun's vicinity early in the 21st century.

On 23 June 2006, one day short of 117 years after Barnard's discovery, the LINEAR survey reported a newly discovered 17th magnitude object at a declination of -27° moving at 2.5"/min, but travelling almost due north. It was put on the NEO Confirmation page later that day and within hours, Luca Buzzi from Schiaparelli Observatory in Italy was first to report that this new object was cometary in appearance, noting that the object showed a 6" circular coma with a strong central condensation in images taken with a 0.60-m reflector. Marsden quickly pointed out that this was a return of Barnard's periodic comet of 1889. He determined that the orbital period for the 1889 apparition was 117.36 years, while the period for the 2006 apparition was 119.64 years.  

This object was assigned as comet P/2006 M3 (Barnard) with IAUC 8726 issued on on 2006 june 26 and astrometry via  MPEC 2006-M38 : COMET P/1889 M1 = 2006 M3 (BARNARD)  and  MPEC 2006-M42 : COMET P/1889 M1 = 2006 M3 (BARNARD)
