  We report here the highest resolution near-IR imaging to date of the HD
141569A disc taken as part of the NICI Science Campaign. We recover 4 main
features in the NICI images of the HD 141569 disc discovered in previous HST
imaging: 1) an inner ring / spiral feature. Once deprojected, this feature does
not appear circular. 2) an outer ring which is considerably brighter on the
western side compared to the eastern side, but looks fairly circular in the
deprojected image. 3) an additional arc-like feature between the inner and
outer ring only evident on the east side. In the deprojected image, this
feature appears to complete the circle of the west side inner ring and 4) an
evacuated cavity from 175 AU inwards. Compared to the previous HST imaging with
relatively large coronagraphic inner working angles (IWA), the NICI coronagraph
allows imaging down to an IWA of 0.3". Thus, the inner edge of the inner
ring/spiral feature is well resolved and we do not find any additional disc
structures within 175 AU. We note some additional asymmetries in this system.
Specifically, while the outer ring structure looks circular in this
deprojection, the inner bright ring looks rather elliptical. This suggests that
a single deprojection angle is not appropriate for this system and that there
may be an offset in inclination between the two ring / spiral features. We find
an offset of 4+-2 AU between the inner ring and the star center, potentially
pointing to unseen inner companions.
