The Sky This Week - Thursday March 1 to Thursday March 8

The Full Moon is Friday, March 2.  Venus and Mercury are close together low in the twilight on March 4. Mars, bright Jupiter and Saturn form a line together with the bright stars Antares and Spica in the morning skies. Jupiter is now rising in the late evening skies and the Moon is close to Jupiter on the 7th (and morning 8th). Saturn is in binocular range of some interesting nebula and the globular cluster M22.

The Full Moon is Friday, March 2.

Evening twilight sky on Sunday March 4 looking west as seen from Adelaide at 20:15 ACDST (30 minutes after sunset). Venus and Mercury are close together low in the twilight.

Similar views will be seen throughout Australia at the equivalent local time (30 minutes after sunset, click to embiggen).

Venus and Mercury are very low in the twilight. You will need a flat unobscured horizon, like the ocean or the desert, and probably binoculars, to be able to see them both low on the horizon murk.

Morning sky on Saturday March 3 looking north-east as seen from Adelaide at 5:37 ACDST (90 minutes before sunrise). Mars is moving towards Saturn and Saturn is coming closer to the bright globular cluster M22.

The large inset is a simulated binocular view of Saturn.  Saturn is close the globular cluster M22.

Similar views will be seen throughout Australia at the equivalent local time (90 minutes before sunrise).

Venus  is low in the evening twilight. and is still very difficult to see, being just two finger-widths above the horizon 30 minutes after sunset.

Mercury is very low in the evening twilight just below Venus. You will need a flat unobscured horizon, like the ocean or the desert, and probably binoculars, to be able to see them both low on the horizon.

Jupiter  is rising before midnight, but it is still best to view in the morning sky, where it is high above the northern horizon. The waning Moon vists Jupiter on the evening ot the 7th (morning 8th)

 Mars is moving down the body of Scorpius the scorpion. Mars moves away from Antares (the rival of Mars) over the week but is still reasonably close to see the contrasts of the two different red objects. Mars is moving towards the Triffid and Lagoon nebulae and Saturn, and is passing many small faint deep sky objects over the week. Scanning with binoculars around Mars and Saturn will be very rewarding.

Saturn climbs higher in the morning sky. It is within binocular range of several attractive clusters and nebula. It is just within range of the Lagoon and Triffid nebulae and is coming closer to the  bright globular cluster M22.

Occultation of Delta1 Tauri by the Last Quarter Moon (23 February 2018)

-

Evening sky on Friday, February 23 looking west as seen from Adelaide at 20:58 ACDST (60 minutes after sunset). The waxing Moon is near the Hyades. Similar views will be seen throughout Australia at the equivalent local time (60 minutes after sunset, click to embiggen).

The inset shows the Moon at 23:21 ACDST, when the Moon is about to cover 𝛅1 Tauri. Timings for major cities are listed in the table below.

For many locations in Australia the First Quarter Moon occults the close pair of stars 𝛅1  and 𝛅2 Tauri in the Hyades star cluster. These are reasonably bright stars, readily visible to the unaided eye, but the occulation is close to the horizon. As the darf edge of the Moon covers the stars you should see them abruptly wink out.

Even if you do not have a clear horizon watching the Moon drift towards the pair of  𝛅1 and 𝛅2 Tauri in the beautiful Hyades cluster will be fascinating.

For many locations, especially on the east coast and central states you will need a flat clear horizon to see the occulation (example horizon views are shown below). This will mean that most telescopic observation will not be possible due to the low angle of elevation, and the dimming of the stars close to the horizon means the occultation may be best viewed with binoculars.

When and what you will see is VERY location dependent, so you need to use either Heavens Above or CalSky to get site specific predictions for your location, a small difference in location can mean the difference between the ISS passing over the Moon (or the stars in Orion's Belt) or missing it completely.
 
As always, start looking several minutes before the pass is going to start to get yourself oriented and your eyes dark adapted. Be patient, there may be slight differences in the time of the ISS appearing due to orbit changes not picked up by the predictions. Use the most recent prediction for your site.

[Aurora Alert] Geomagnetic warning and Aurora Watch (14-15 February)

The SWS has issued a geomagnetic warning and aurora watch for 14-15 February (UT) due to expected arrival of a CME from a recent solar flare. This is expected to arrive early in the UT day on the 15th (which is the early evening  of the 15th Australian time) and may persist unlit shortly after midnight.  The SWS predicts active conditions. The Space Weather Prediction Service and NOAA has Predicted a G1 storm on the evening of 15 February.

If these geomagnetic events occur and result in aurora they could be seen from Tasmania weather permitting. The Moon is new and will not interfere with aurora. Be patient, as the activity may rise and fall of the magnetic polarity of the wind may fluctuate significantly.

This event is unlikely to be as spectacular as those in last year, but still worth a look as viewing conditions are good.

Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.
As always look to the south for shifting red/green glows, beams have been reported consistently over the last few aurora, as well as bright proton arcs and "picket fences". A double arc,  blobs, and curtains were seen in Septembers aurora  last despite the moonlight.

Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
Cloud cover predictions can be found at SkippySky.  

A new aurora camera is being installed at Campania, Tasmania. A live feed of the images from this camera is still not available.

The asteroid 1 Ceres is relatively easily visible in binoculars until around the middle of this month, it fades during this time.

Ceres is relatively easy to find. It is above the northern horizon just before midnight , and is near Iota Cancerii (the bottom brightish star of Cancer. You may need to watch night to night as the asteroid moves to be sure of its identity.
 
Venus  is lost in the twilight.

Mercury is lost in the twilight.


Jupiter climbs still  higher in the morning sky and is moving away from Mars.

 Mars is moving down the body of Scorpius the scorpion. Mars moves away from Antares (the rival of Mars) over the week but is still reasonably close to see the contrasts of the two different red objects. Mars comes very close to several dim globular clusters. These are telescope only events and the brightness difference between Mars and the dim clusters will make to them to see, on the 20th Mars is nearly on top of magnitude 9 NGC 6235.

Saturn climbs higher in the morning sky. It is within binocular range of several attractive clusters and nebula, including the Lagoon nebula and the bright globular cluster M22.

The bright planets form a line in the morning sky  with the bright stars Antares and Spica, this will look quite attractive.

Nearly halfway over 1:12 ACDST (1 Feb)Totality just ending 00:42 ACDST (1 Feb) Canon IXUS with infinity-infinity focussing on telecope

After much anticipation (and organising of Moon viewing with friends) January 31 dawned cloudy. Skippy Sky, which had previously been optimistic, showed something like 90% cloud cover for the night.

None the less I got the 114 mm Newtonian reflector out, I thought there wasn't much point with the big reflector as there was a chance of rain, I could quickly move the small reflector into cover.

The Moon rose as a vaguely brighter patch in the cloud, hasty conference with friends and it was decided the Moon party was off. Checked occasionally but nothing to see until around 11:00 when my Beloved Life Partner, returning from Choir, pointed out a half eclipsed Moon peeking through the hazy overcast.Didn't see much of the  livestreams as I was popping in and out so much.

Got the cameras out, but the Moon played hide and seek until just after totality started. It was still covered with hazy cloud, but I could get some images with my mobile phone (just held to the 10 mm Plossl lens). Clouds thickened and thinned, but the sight of the ruddy Moon glowing through the haze was beautiful. MiddleOne came home late and I was able to show him the eclipsed Moon, he was impressed.

AS the eclipse came to the end, I had my canon IXUS set up with its special holder to image the end of the eclipse, I only got a couple of shots off before the battery ran out (drained from my attempts to image with uncooperative cloud).

I imaged the rest of the eclipse with my mobile phone again, most of the images are fuzzy because of the hazy cloud, but around halfway though the end of the eclipse a hole in the cloud came over and I was able to get a clear image. Then a huge bank of cloud covered the Moon, and I packed up the equipment and went to bed.

Despite the cloud, it was a beautiful eclipse, and the diminishing crescent playing hide and seek in the haze was a very different  atmosphere to any other eclipse I have seen. Well worth it all.

Southern Skywatch February 2018 edition is now out!

Evening sky as seen on February 12 at 5:13 ACDST, with the crescent Moon close to Saturn and globular cluster M22. The inset shows the binocular view. Similar views will be seen elsewhere in Australia at the equivalent local time (90 minutes before sunrise click to embiggen).

The February edition of Southern Skywatch is  now up.

This month  still sees most of the action move in the morning sky. Speedy Mercury  and Venus return to the evening sky, but Venus will be hard to see until next month.

 Mars and  Jupiter climb higher in the morning sky. Mars comes close to several faint globular clusters this month.




Saturn is close to the Triffid and Lagoon nebulas and several clusters this month.

 February 1; Mars very close to star beta1 Scorpii.

February 8; Moon close to Jupiter. February 9-10; Mars and Moon close.


February 11; Moon at Apogee. 

February 12; Saturn and crescent Moon close, with M22 nearby.

Feb 1-13; Asteroid Ceres visible in binoculars.
