Comment: След оценка на яркостта на кометата трябва ли да се използва редукционната формула за привеждане на блясъка към 6.78см апертура? М=m-a(D-D0)

Comment: Why has the object not yet receive a cometary designation by the Minor Planet Center? For the MPC, it is still 2013 UQ4, not C/2013 UQ4. Jean Meeus

Comment: I was looking at JPL's close approach data and from the observation made on 5-6-14 the close approach date is wrong. It will be closest to earth on 5/15/14 at 0.12 AU and further away on 5/29/14 it is 0.168 AU. I am not an astronomer and maybe I am confused on this.

Comment: Congratulations, Artyom and Taras! Now it looks that the period is only 491 years, so the comet isn´t new from the Oort cloud. I´m a bit afraid that the comet will be very diffuse when it will be close to Earth. But that doesn´t mind very much because it probably will be binocular object. I look forward to this comet. Congratulations again!

Comment: Yes I also observed it as a comet by iTelescope T17. The total R-band magnitude was estimated as 14.5 within a circular aperture of radius 12".8. The outer coma was not imaged on 6 stacked images of 30-sec exposure.

Comment: Excellent article. This comet is currently visible above northern horizon and does not set for northern latitude observers. Charles Bell
