Lea gave a rhymed answer to this riddle
which is quite good. Here is the answer in prose.
>The heavens lie before me,
>but usually not as a sphere.
Usually an astrologer will look at a chart of the heavens.
This is two dimensional and not a sphere.
> I’m constantly moving,
> roving here and there.
Not only does the astrologer move around
his or her eyes also rove around the chart.
>I always need a day,
>can always use an hour.
To be able to do any accurate astrology
a date is necessary and usually available.
The exact time is also very helpful but not always given.
>By now you should know me.
>You’ve seen my starry eyes.
I am a stargazer. Or should be.
>Can you tell me who I am?
