КомментарийC/2014 Q2 Lovejoy January 15th 00:16 UT 25X100 Binoculars 25X SQM 17.35 Alt 29.73 M1 3.9 During Storm Rachel yesterday , last night, today and now (almost over ) there was a break in the intense rain. Much to my surprise the sky cleared at about 23:30. or so. The wind was very strong and some of the gusts were scary. However I quickly gave in to curiosity and set up the binoculars in our patio. My binoculars weigh 4.5 kg (10 lbs ) and my tripod weighs 20 kg (44 lbs) so I was reasonably happy that the set up would not get blown over. Nevertheless I held on to it during the gusts . My first view of Lovejoy again revealed a hint of green , which this time lingered in the view. I placed 5 Tau at the bottom of my view as it was so orange and distinctive . C/2014 Q2 Lovejoy looked great in the same fov . As I looked closely ( ignoring the wind) I noticed a star very close to the condensed mass which seemed to be more toward the head of the comet than before. This star was a real pinpoint bright compared to the comets material . I wondered if the comet had occulted the star and it was remerging at just that moment ? It was difficult to make out if the star was within the edge of the coma or just on the edge of it . When I checked out the star later it turned out to be an 8.65 magnitude star . To me it looked really bright as it was close to the grey/ white particles of Lovejoy's coma. All together my view was both exciting and beautiful, the comet was briefly bright similar to my Jan 13th view but the conditions were atrocious. Temptations to drag out the telescope were also ignored as 45 minutes of wind bashing was enough for me. Still hoping to kidnap a friend to go somewhere dark ......soon.
