INTERIM REPORT ON NORTHERN EQUATORIAL REGION

John Rogers (British Astronomical Association), 2004 March 8

Summary

The northern equatorial region [EZ(N) and NEBs] is particularly active and interesting this apparition, and is in a similar state to that during the Voyager encounters in 1979.  Common features are:

1) Weak yellowish shading in EZ(N)

2) Prominent NEBs dark projections and bright plumes

3) A long-lived rifted region in NEB.

Moreover, two phenomena are being observed in 2004 which confirm discoveries made in the 1979 data:

4) NEBs dark projections are enhanced when passing the NEB rifted region;

5) In EZ(N), UV-bright areas are displaced from the corresponding visibly-bright areas.
