64P/Swift-Gehrels @ February 9,2019 23:42 UT

Comet 64P/Swift-Gehrels photographed on February 9th 2019, a month after to beginning a drastic activity reduction shows a poor appearance since my previous image taken on January 5th. Its brightness has decreased from magnitude 9 to 11.5 and angular size of coma from 8 to 3 arcminutes. A couple of zones without stars reveal the presence of a pair dark nebulas in this region of Taurus constellation: Barnard 19 at left and Barnard 218 to right.

Acquisition details:
Telescope GSO 8" N f/3.8.
Camera Atik 383L+.
11 min. total exposure.
From Vallés, Valencia (Spain).
