The moment is 13 hours by Universal Tim, which, by standard time, is 5 and 8 hours earlier in North America’s Eastern and Pacific time zones; but, by clocks still on the distorted summer time, one hour later than that.
It happens that I’m working on the “Uranus and Neptune” section of the Astronomical Calendar for next year (which should be available quite soon). It will be the year in which Neptune crosses the equator northward – a triple event, because of the planet’s apparent retrograde motion when we are overtake it. It will slide northward across the celestial equator, back south, then again n north, after which the two blue-tinted “ice giant” planets will both be in the north celestial hemisphere for the next 42 years.

ILLUSTRATIONS in these posts are made with precision but have to be inserted in another format. You may be able to enlarge them on your monitor.
One way: right-click, and choose ”View image” or ”Open image in new tab”, then enlarge. Or choose ”Copy image”, then put it on your desktop, then open it. On an iPad or phone, use the finger gesture that enlarges (spreading with two fingers, or tapping and dragging with three fingers). Other methods have been suggested, such as dragging the image to the desktop and opening it in other ways.
Sometimes I make improvements or corrections to a post after publishing it. If you click on the title, rather than on ‘Read more’, I think you are sure to see the latest version. Or, if you click ‘Refresh’ or press function key 5, you’ll see the latest version.

Could you explain your question more fully? Return to opposition?
