Wednesday 28 September 2011

Weather: Clear but hazy
Time: 8:30-9:30pm approximately

It was a little bit disappointing tonight. It took me a while to align the telescope and there was this haze across various parts of the sky. Pretty much ruined it. Actually, the telescope is still out of alignment but I can compensate for that. It makes finding things a bit difficult though. The Southern Cross was partly behind the bush but I still managed to find the jewel box. I tried to find M7, just off the tail of Scorpius but was unable to due to the haze. Also, my arm really hurts as I have bursitis. I still saw some constellations. Hopefully it will be a clearer night next time.

Saturday 24 September 2011


Weather: Clear
Time: About 10:00pm
Location: Footbridge Lodge

I had the opportunity to view the night sky from Footbridge Lodge as it was the place of my brother's wedding reception. I didn't get much time to see anything but I did see a few things. The stars shone brightly and clearly, peeking out between the trees. Occasionally birds flapped overhead and doves cooed in the trees. Large pines poked into the sky like tent poles, holding up the great canopy of stars and obscuring some at the same time. Scorpius' tail stuck out cheekily, its head diving towards the horizon. Then to the left sat a hidden treasure, Corona Australis, the Southern Crown, twinkling jewels in a crown-shaped form.

I had difficulty finding the Southern Cross as it was obscured by cloud, but I did locate the pointers. In the evening, the Southern Cross is low on the horizon. At my house, you can't see it at all because it is behind the trees.

Also visible was the Triangulum and Eridanus, led boldly by Achernar.

After I left Footbridge I tried observing from my car window. This proved difficult for two reasons. First, I had to crane my neck to see anything and this was slightly uncomfortable and secondly, I would just be coming to grips with what was in the sky when the car would turn and I would be facing a different direction. However, being away from the city lights meant that the stars stood out and shone brightly.

Constellations

Scorpius: The Scorpion
Bright Stars: Antares (red)

Aquila: The Eagle
Bright Stars: Altair
Notes: In Greek myth, Aquila is the eagle that carries the thunderbolts of the god Zeus.

Triangulum: The Triangle
Notes: This triangle sits near the two pointers, Alpha and Beta Centauri, just below. It is worth locating because it can be used to help you find other constellations in the sky.

Centaurus: The Centaur
Bright Stars: Centaurus contains the closest star to Earth apart from the sun, Alpha Centauri. This star is only 4 and a 1/2 light years away. A light year is how far light travels in a year. Light travels approximately 5.88 trillion miles in a year. So it takes light from Alpha Centauri about 4 1/2 years to reach us. This means we are looking back 4 and a 1/2 years when we see Alpha Centauri. Alpha Centauri is really a group of three stars. If you look at Alpha Centauri through a small telescope you can see two stars.
Notes: Centaurus is the 9th largest constellation in the sky. This is in comparison with the Southern Cross, or Crux, which is the smallest constellation in the sky. A Centaur is a creature that is half human and half horse. I didn't really get much of a look at the whole constellation, only Alpha and Beta Centauri.

Corona Australis: The Southern Crown
Notes: This is such a beautiful constellation. It is one of my favourites. It is a few stars set in a semi circle, or crown shape. It is very difficult to see but if you have good eye-sight you may be able to make it out. You need a dark night to see it well. Another crown in the sky is the Corona Borealis or Northern Crown. This is close to Bootes, which you can't see at the moment. I guess the Coronas are like tiaras.

Eridanus: The Celestial River
Bright Stars: Achernar
Notes: Achernar was on form last night. It was very bright. It is the end of the river. Eridanus is the 6th largest constellation.

Phoenix: The Phoenix
Notes: This sits just above Eridanus and Achernar.

Notes: In Greek mythology, Scorpius killed Orion the Hunter with his stinger. Antares is a red star. Antares means "rival of Mars". It is known as the heart of the scorpion as it is near the middle of the scorpion. It is easy to make out the shape of the Scorpion in the sky.

I saw a satellite near Aquila around 8:00pm

Amateur Astronomer

Hi,

I'm an amateur astronomer from New Zealand. I enjoy looking at and studying the night sky above my house in Auckland. I've learnt a lot these past few years: The names of many constellations in the night sky and how to find them, the names of many important stars, and I've recently started learning the names of the stars and constellations in Maori, the indigenous people and language of New Zealand. I haven't studied astronomy at university or anything like that. I simply enjoy learning and reading about astronomy and related subjects. In this blog I want to record what I see in the night sky above my house and anything else that is interesting.
