In June of the same year, Johann Fabricius published a page book De Maculis in sole observatis et apparente earum cum Sole conversione narratio in Wittenberg, in which he describes all the details of the discovery and credits his father with a due share.

De maculis in sole observatis: Description This short booklet of less than 50 pages all in all is the first published description of the phenomenon of the sunspots. It opens with a dedication to a Frisian politician and a laudatory epigram or short elegy to the author.

The work itself begins with a report of Fabricius’ discovery of the sunspots.

Solar rotation is able to vary with latitude because the Sun is composed of a gaseous rate of rotation is observed to be fastest at the equator (latitude φ=0 deg), and to decrease as latitude increases.

The differential rotation rate is usually described by the equation. where ω is the angular velocity in degrees per day, φ is the solar latitude and A, B, and C are constants. Several months later, he published his discoveries in a study called De Maculis in Sole observatis et Apparente earum cum Sole Conversione Narratio.

This first publication on such observations, was the work of Johannes Fabricius, a Dutch astronomer who was among the first ever to observe sunspots through a telescope. The English scholar Thomas Harriot was probably the first to observe sunspots telescopically as evidenced by a drawing in his notebook dated December 8,and the first published observations (June ) entitled “De Maculis in Sole Observatis, et Apparente earum cum Sole Conversione Narratio” ("Narration on Spots Observed on the Sun and their Apparent Rotation with the Sun") were by.

The son of the astronomer David Fabricius, Johannes used a camera obscura as well as a telescope Narratio prima (work by Copernicus).

The Fabricius correctly interpreted the day-to-day motion of sunspots as an indication of the Sun's axial rotation, and the young Fabricius completed in June of the same year a short account of their observations and interpretation, which was published in June under the title de Maculis in Sole observatis et apparente earum cum Sole.
