On April 10, Jupiter, still bright on an early spring evening, will be clearly visible to the naked eye, and to its right, just 3.5 degrees, 5 percent phase, a thin two-day crescent.
At 8:20 p.m., the pair is still 15 degrees high in the lower western sky. The announcement stated that it would be easy to see celestial bodies with the naked eye if the western horizon was clear and free of features.
As written, bluish-green Uranus — which lies just 2 degrees above Jupiter — will also appear in the sky as well as one of the most beautiful comets of the year, 12P/Pons-Brooks, which can be seen 3 degrees below the Earth's surface. Crescent moon.
According to information, it is useful to wait until the sky is completely dark in order to see the faint planet Uranus and the comet, which cannot be seen with the naked eye. At around 8:50 p.m., both celestial bodies could already be observed in the night sky, but by then, the pair of Jupiter and the Moon had fallen to an altitude of 10 degrees, and the comet to only 7 degrees. In order to see them, you need a clear sky and a larger, hand-held telescope.
Jupiter, now at the end of its visibility, returns to the morning sky in May 2023, but as it approaches the sun, it slowly disappears in the evening twilight. This is also the last chance to view Uranus.
Comet 12P/Pons-Brooks will reach perihelion, the closest point of its orbit to the Sun, on April 21, but will no longer be visible. It will then approach Earth again after 71 years. Like Jupiter and Uranus, 12P/Pons-Brooks will be visible during the evening.
A crescent moon about two days long with 5 percent illumination will still be visible. The announcement said that the glow of the unlit side of the moon, that is, grayish-gray light, would be clearly visible to the naked eye.
Between April 11 and 13, interested parties can also observe the craters of the ever-waxing vernal crescent at the Svábhegy Star Observatory, the summary said.
