Am fotografiat in aceasta seara cometa C/2013 X1 (PanSTARRS) in Pegasus.

Comparand-o cu o imagine din 4 decembrie 2015 se observa coama mai dezvoltata:

Buna imagine. Acum am o intrebare. Dupa opinia ta, a mai crescut in luminozitate, sau a inceput deja sa scada?

Inca e in crestere, conform si http://www.cobs.si/analysis
Eu am masurat-o in 2015-12-04 ca avand 17N si in 2016-01-14 13.8N.

Citat de pe siteul lui Seiichi Yoshida http://www.aerith.net/comet/weekly/current.html


"It brightened in outburst in early January. Now it is very bright as 8.0 mag (Jan. 8, Maik Meyer). It will pass close to the earth from spring to summer, and it is expected to brighten up to 4-5 mag. In the Northern Hemisphere, it will be unobservable in late February. It will appear in the morning sky again in late April, but it locates low in the south around the high light. In the Southern Hemisphere, it will be unobservable soon. But after appearing in the morning sky again in mid April, it will be observable in excellent condition."
