If you check out this page and go down to the IMF seaction the 3rd chart to the right is the imf azimuth. It is now at dusk

Hi Conor - the definition of the IMF Azimuth on the site you posted is:

(Derived) This quantity is the direction of the IMF perpendicular to the geomagnetic axis. This affects the details of solar wind-magnetosphere interactions; however, this is of tertiary importance compared to the IMF magnitude and polar angle. This quantity also depends on IMF components measured by ACE/MAG.

I'm not sure how it can be dawn, dusk etc ....

Cheers
