The Sky This Week - Thursday February 6 to Thursday February 13

The  Full Moon is Sunday, February 9. Venus is prominent in the evening sky well after twilight. Three bright planets are now visible in the morning skies. Mars is visible in the morning sky below the body of Scorpius the Scorpion moving through the heart of the Milky Way.  Jupiter is visible below Mars and above Saturn. The Red Giant star Betelgeuse in Orion is still dim.

The  Full Moon is Sunday, February 9.  The Moon is at perigee, when it is closest to the Earth, on February 11.


Sky at 21:17 ACDST on Saturday, February 8 (60 minutes after sunset) looking west as seen from Adelaide. Venus is prominent in the sky. The inset shows the telescopic view at this time.





Similar views will be seen elsewhere in Australia 60 minutes after sunset, click to embiggen.


Morning sky at 5:42 ACDST facing east as seen from Adelaide on Saturday, February 8, 60 minutes before sunrise.

Three bright planets are now visible in the morning skies. Mars is now well above the horizon and is below the body of Scorpius the scorpion. Mars is in some interesting binocular territory as it crosses the milky way and heads towards the triffid and lagoon Nebulae. The inset is the binocular view of Mars and the nebulae on the 13th.

Jupiter is higher above the horizon and Saturn appears below it.

Similar views will be seen elsewhere in Australia at the equivalent local time. (60 minutes before sunrise, click to embiggen).

Evening sky looking north-east at 21:52 ACDST on Saturday, February 8 (90 minutes after sunset). Similar views will be seen elsewhere in Australia at the equivalent local time. Orion is readily visible. Betelgeuse is the bright red star below the "saucepan" of Orion. Red Aldebaran is almost the same height above the horizon as red Betelgeuse, making brightness comparisons easy.

Betelgeuse is a red giant star which forms a distinctive part of the Constellation of Orion. It is a variable star, with small fluctuations in brightness not visible to the casual observer.

Betelgeuse has dimmed substantially and is now reportedly around magnitude 1.6, it is visibly dimmer than magnitude 1 Aldebaran and roughly as bright as Bellatrix. The next brightest star just to the north of Betelgeuse. Keep an eye on this historic dimming event, observing hints and stars for magnitude estimation are given here. The waxing and full moon will  interfere with estimates of  Betelgeuse' brightness during the week.

Venus is prominent above the western horizon in the early evening sky. Venus is now readily seen up to 90 minutes after sunset.

Mercury is lost in the twilight.

Three bright planets are visible in the morning sky.

 Mars is visible high in the morning twilight. It is below the scorpion, Scorpius, this week. Mars is in some interesting binocular territory as it crosses the milky way and heads towards the triffid and lagoon Nebulae.

Jupiter climbs higher in the morning sky.

Saturn climbs higher in the morning twilight.
