And Vesta is at opposition.
April final fool! We’ve crossed the boundary from a 30-day month to a 31-day month. But the brightest asteroid really is crossing the boundary from the morning to the evening sky – directly outward from the Sun, on the midline of the midnight sky. Here is the finder chart from page 127 of Astronomical Calendar 2025.
It shows that that Vesta also happens to be crossing the boundary from Libra into Virgo. Vesta is shining at magnitude 5.6, just within the unaided-eye limit. Slightly brighter is the star Mu Virginis, magnitude 3.8.

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.
