This is an image obtained with the 0.91-meter Spacewatch Telescope
of the University of Arizona Observatories on Kitt Peak in Arizona by Jim
Scotti, on 1993 March 30 at a mid-time of 07:26:13 UT. The total
integration time was 440 seconds. North is to the right and East is at
the top with the frame label properly displayed in the top left corner of
the border. The field of view is 9.2 arcminutes square. Note the various
structures visible in this image. Namely, the train of individual nuclei
aligned along a position angle of 77 to 257 degrees. Approximately 11
nuclei are visible in this image of the train, spread out over 51
arcseconds (or about 170,000 kilometers). A tail extends from each of the
nuclei approximately 1 arcminute towards p.a. 285 degrees, with a brighter
component extending from the brightest nucleus out to about 1.2
arcminutes. Dust trails extend more than 10 arcminutes in p.a. 260
degrees and 6 arcminutes in p.a. 75 degrees. Notice also that the
southern margin of the dust trails is relatively sharp while the northern
margin is more diffuse. This may be due to smaller particles being blown
off by the solar wind.
