My first shot of comet Schwassmann-Wachmann 3 has positioned in central region of Virgo. Component C in left flame has a visual brightness of 13th magnitude and a tail with its length of 3 arc minutes in west direction. And component B in right has positioned about 45 arc minutes north west of component C. You can detect a very small light spot in center of the flame with its brightness of 16th magnitude and an indistinct tail stretched toward west.
