This picture is the sum of four 10s,
three 20s and five 5s exposures without filters. They were taken
from 5:12 to 5:19, from 5:22 to 5:26 and from 5:27 to 5:36 UT.
The field size is 5.2×5.2 degrees. The filaments visible
in the dust tail to the right are synchronic bands of material ejected at
the same time from the nucleus, first observed by Fukushima and collaborators (National
Astronomical Observatory of Japan) the 6th of March (see our section
dedicated to the latest news on comet Hale-Bopp). |
