Objects observed: C/2014 Q2 (Lovejoy)

Comet C/2014 Q2 (Lovejoy) is now well visible in the night sky of Northern hemisphere. The comet is now dwelling in the constellation of Taurus, where it can be seen as a fuzzy 4th magnitude star with naked eye! Yesterday evening I went to observe this icy nomad by myself.

I was observing the comet with my 4” refractor. With my instrument, the comet appeared as a round, fuzzy ball of light. In the coma of the comet, there is a clear central brightening. The coma is getting gradually brighter towards the center. There is no visual tail visble with the comet. The apparent diameter of the coma of the comet is about 21′. The degree of condensation of the comet is about 6 in the scale from 0 to 9.

Degree of condensation is just a way to describe how the light of the comet is distrubuted in the object. If degree of condensation is very low, then the brightness distribution is very even, but if degree of condensation is high, then the coma of the comet is almost stellar in appearance.

I was also able to observe the comet with naked eye. With naked eye it appeared as a fuzzy, 4th magnitude star in the constellation of Taurus.
