If skies are clear at dusk in Western Europe and the UK on Tuesday, 19 February, be sure to glance up at the full Moon in the constellation of Leo. If the lunar orb seems a bit larger than usual then you’d be right, for this is the closest full Moon of 2019. Since it occurs just 6¾ hours after lunar perigee, it’s also a supermoon. And if it’s cloudy, you can watch online!
Grab your binoculars to catch a glimpse of speedy Comet C/2018 Y1 Iwamoto over the coming week before the glare from a full Moon on 19 February drowns it out. Potentially attaining magnitude +6, the comet passes closest to Earth on 12 February when it can be found traversing Leo at a rate of 7.2 degrees/day. Don’t miss C/2018 Y1’s close enounter with galaxy NGC 2903 on 13 February – by eye, camera, or live online.
Have you ever seen planet Uranus? If skies are clear in the UK and Western Europe on the evening of Sunday, 10 February, see this icy gas giant less than 2 degrees (or four lunar diameters) from Mars and 6 degrees from the 5-day-old crescent Moon. In fact, you’ll see all three in a single view of wide-angle binoculars like 7×50s.
Have you ever seen the International Space Station (ISS)? It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 450-tonne, 109-metre-long spacecraft over the British Isles and Western Europe this week.
Skywatchers in the UK and Western Europe should look low to the south-southeast an hour before sunrise on 31 January to see a beautiful naked-eye conjunction of Venus, the old crescent Moon and Jupiter, all within a span of 8½ degrees. But if you have a telescope and live in just the right place, you can also see the Moon hide a double star.
While you may not relish the prospect of waking up in the small hours most Monday mornings, observers in the British Isles and Western Europe will want to set their alarms no later than 5am GMT on 21 January to see this month’s showstopper celestial event — a total lunar eclipse of an unusually close ‘supermoon’. The total lunar eclipse is also visible in its entirety (weather permitting) from the Americas.
As dusk fades to dark on Thursday, 17 January, observers in the British Isles and Western Europe can see the rising 10-day-old Moon less than 1 degree away from first-magnitude star Aldebaran in the constellation of Taurus. Grab your binoculars to enjoy the sight of the gibbous Moon amid the Hyades open star cluster too.
Observers should direct their gaze to the southern sky at dusk on Saturday, 12 January to view the 6-day-old waxing Moon in the constellation of Pisces. Look a little closer around 6pm GMT in the UK this night to see Mars as a magnitude +0.6 orange-coloured ‘star’ above the lunar crescent. If you own wide-angle 7× or 8× binoculars, you can see the Moon and Red Planet in the same field of view.
Brilliant planet Venus attains its greatest elongation almost 47° west of the Sun at dawn in the UK on Sunday, 6 January. Find a location that offers you a view down to the southeast horizon around 7am GMT and you may catch a glimpse of Jupiter too. The planetary duo is currently 14 degrees apart, but drawing nearer for a close conjunction on 22 January.
