Astronomy Guide February 2023

Dear Stargazer Friends,

Comet C/2022 E3 (ZTF) will remain visible through early February and will later be observable from the southern hemisphere. On 9 February, it should be visible near Mars. 

Venus has become much more prominent since early January. On 22 February, look for Venus, Jupiter and the waxing crescent Moon at around 19:00 h (W). Saturn will not be observable until May 2023. 

The constellation of Orion moves across the meridian (meridian transit; the meridian is an imaginary circle that passes through the celestial poles and an observer’s zenith) much earlier now (around 22:00 or earlier). In the East, the constellation of Leo – herald of Spring – is now already visible. For observation and astrophotography, the constellations of Cancer, Canis Minor, Monoceros and Gemini offer many fascinating celestial objects. In the early pre-dawn mornings, the constellations of Scorpius (SE) and Cygnus (NE) are visible again 

Clear Skies and best wishes,

Comet C/2022 E3 (ZTF)

C/2022 E3 (ZTF) had its closest approach to Earth on 1 February 2023 but remains visible all night in early February. It has increased in magnitude. From a dark site, it should be observable with the naked eye. With binoculars, you should be able to see it also from more light polluted areas.

Phenomena not to miss in February

The transit of the constellation of Orion is now already around 22:00 h or earlier. At the same time in the eastern part of the night sky, the constellation of Leo with its brightest star Regulus can now be observed – a herald of Spring. For observation and astrophotography, the constellations of Cancer, Canis Minor and Monoceros offer many interesting celestial objects, from Nebulae (Rosette nebula aka Caldwell 49 in Monoceros) to Open star clusters such as Praesepe in Cancer (Messier 44). In the constellation of Gemini watch out for the Open star cluster Messier 35, and Double Star Castor (a Gem). In Canis Minor, Double Star Procyon (a CMi).
