(meteorobs) Comets of 1668 and 1843

[Pat Branch]

If the comets of 1668 and 1843 are the same (period of 175 years versus 170 year period calculated for 1843 long ago)...then there should be a repeat in late Feb 2018.
Is it too early to start looking for that comet in large telescopes? If we assume they are the same, then we can correct the rough orbit of 1843 with the predicted 2018 passage time and get a rough current location.
Are we still 2-3 years away from being able to spot it?
