Spring apparently means clear nights!

Well, this is Melbourne, so when I say 'clear nights' I really mean 'one clear night amongst the many murky ones.' Nonetheless: today it hit 20C for the first time in many months, there were lovely clear blue skies for most of the day - I sat outside and read! - and it stayed clear for the evening.

We started off looking at Venus, which was a delightful thin crescent. Then, waiting for the sky to darken at least a little, over to Alpha Centauri; split beautifully.

It didn't ever really properly darken tonight; probably we didn't leave it quite late enough. Anyway, Antares (the anti-Ares, ie Mars; cool!) was a lovely reddish colour, and I discovered that beta Scorpius, aka Graffias, is a double: a pair of whiteish-blue stars. Another of the Scorpius stars is also a double, but I did not split it - although it did look quite bulbous, so perhaps I was close.

Close to Scorpius is M7, which I managed to find all by myself - at exactly the same time that J found it through Copernicus, which was quite funny. It's a lovely open cluster, with a nice scatter of stars. Close to it is M6, but I did not manage to find it, which made me a little grumpy. To make up for it J pointed me towards Cr316, which I'd been thinking of finding anyway. It too is an open cluster, but (optically at least) much tighter than M7. Through the 35mm lens, it was quite spectacular.

Testing out just how good my eyes are, and how light the sky was, I next looked at the star G Scorpius, because next to it is a globular cluster, 6441: very faint from here, and you'd just assume it was a smudge if you weren't looking for it. In fact, my next target - M22 - I didn't even see even though I was looking for it. I got - ahem - a little petulant; J had a look to see where I was at... and it was there, in the eyepiece, I just hadn't noticed. Too faint!! - it's another globular cluster.

Really, all of this was a prelude to the main event, which was Jupiter. In order to get the earliest view possible, J decided he needed to do some gardening: bits of a climbing rose were waving about too high. Up a ladder, with secateurs, with only a red headlamp for light... awesome. Anyway, it was a totally classic view of Jupiter tonight. All four Galilean moons lined up, nicely spaced out. Jupiter itself still looking kinda weird with only one dark belt of clouds.

It was a great night's viewing, in all, and not even too cold. Also, not many insects! I'd like to observe in conditions like this all year rounf!

Clear skies are here again

It's been a while. Tonight, for the first time in a while, we had both clear skies and the energy to do something with them. Here's hoping Melbourne gives more of the same! - after the rain that's forecast for the end of this week, in any case.

Anyway, given the skies and the fact that even when the sun was barely down I had a good view of crescent Venus, I messaged some friends just down the road that they should bring their kids over for a look - I'd been meaning to do so for ages. They promptly arrived with two in tow, the eldest being sensible and staying home, feeling sick. We trooped out the back and had a good look at Venus, and Mars - just a blob these days - and had a chat about planets. Then, because the stars were coming out and they were enthusiastic, J decided to show off and show them the Jewel Box; I met that with Alpha Centauri, which split beautifully and particularly excited the youngest. All of which was very pleasing.

We went back out a few hours later, because it amazingly remained clear. Sagittarius and Scorpio are back to being high in the sky - it's like seeing old friends! It wasn't particularly dark, but J hopped around some clusters in the two - M4, M6, and M7; M20 and M21 - the Triffid, looking pretty awesome even with the light pollution. Right when we thought we were ready to pack it in, J had a last look all round the sky. And there, my friends, at -2.5 mag, was dear old Jupiter! I can't tell you how ridiculously exciting it was to see it hanging there so brilliant. Io, Europa and Callisto were nice and obvious, as was the one dark band of clouds that it has left. J thought he might have caught sight of the Red Spot, but I am unconvinced. I stared at that disk for quite a while before achey eyes drove me inside.

Praise the Lord for clear skies

For the first night in a while, we have a delightfully clear night - so far, anyway. It's also almost warm! Which is exciting.

We started viewing at about 8pm, when by no stretch of the imagination could it be called dark. But I wanted to see what Jupiter looked like without a black background. Answer: like Jupiter against a dark blue background. There's three moons out right now, but having checked Stellarium I know Europa is coming out of occlusion right now. So excuse me while I go see if I can see it happen...

Some time later...

Well, we eventually did see it come out - which was cool. I don't know why, given the other three moons are just pinpricks in our eyepiece, but for some reason I was expecting to see a bulge in Jupiter's side! Instead, at first we thought it was us seeing what we expected to see, and then we knew it was there: a little pinprick moving slowly away from Jupiter's mass. By the time we went inside it was still quite close to Jupiter, and fainter than the other moons. I also some a meteor while looking at the planet - presumably part of the Orionid mob.

Meanwhile, waiting for Europa, we looked at other stuff too. We're learning our way around the sky, so we figured out which stars were Altair, Formalhaut, and Antares - three of the brightest stars up at the moment; we already know alpha and beta Centauri (the Pointers, of course); the other bright stars aren't visible from our high-fenced courtyard.

We'd figured out some interesting objects to try and see, from an October sky map, but we hadn't really taken magnitudes into account. M6 looked impressive - diffuse but big clump of stars; M7 was a bit faint. M8 - one of my favourites when we were in Ballarat! - was quite disappointing; took some imagining to see the Lagoon at all, although the stars were impressive enough. M20 was also a bit disappointing, while M22 was a very faint blob of nebulosity. (The Messier Icon Sheet is a quick and easy way to figure out what I'm talking about!) We totally failed to see several other objects we had hoped to see in that same area of Sagittarius. We did manage to see NGC 6231 - it's very reliable, and one of J's favourites. At least partly because you can actually see the whole clump of stars in the finder scope so you know when you've found it!

As well as scoping out the sky we also counted the stars - part of a project to map light pollution around the world. You have to find the Teapot (part of Sagittarius) and count how many of the stars you can see (there's a guide sheet). Our back yard is mag 4; J claims he could just see the stars that would make us mag 5, but I'm not convinced.

Eventually came inside at about 9.50! My eyes were pretty sore by then - I was having trouble focussing on Jupiter, which is what I looked at most. But it was a very, very awesome night of observing. Pity it's meant to cloud over this evening...

Second night's viewing!

Not as cold tonight as last, which was a relief; or perhaps I was better rugged up. At any rate, we stayed outside for maybe an hour and a half, and only my nose got a bit chilly. Also, we decided to take the laptop out, set up on a stool under the tripod, with Stellarium loaded up so we could have a go at finding some stuff.

Firstly, Jupiter - again. I might have seen three bands this time; certainly two dark bands were quite visible. Io and Europa quite close in; I was rather hoping that if we stayed up long enough we'd see a transit, but J looked it up and apparently they will pass behind. This has therefore become a goal - to view a moon transiting Jupiter. Can't be that hard, surely? A matter of diligently reading the ephemeris when Jupiter is clearly visible, I presume.

Next, we swung over west to have a look for some stuff in and around Scorpius and Sagittarius. I've never been very good with constellations; it was very exciting for me when I learnt to pick out all of Orion, a few years ago. One of my big achievements for the evening therefore is now being able to pick out Scorpius! He's very obvious when you know where it is, and actually makes sense as a scorpion's tail. I can roughly pick Sagittarius, too - although he doesn't make nearly as much sense as Scorpius. And Capricorn, which I basically made out because Jupiter was in it, is just bizarre as a goat.

Tonight we had a look at a number of Messier objects: the Butterfly Cluster (M6; not entirely positive we saw this one, actually - we tried hard thoguh), M7, the Lagoon Nebula (M8), the Eagle Nebula (M16), the Omega Nebula (M17), the Trifid Nebula (M20 - I think I saw dust lanes, but I'm not positive), M21, M22 and M28 (both of the last two are globular clusters; M22 was quite bright and I could pick a few stars in it). Some of these objects were smaller than I had expected, but some were quite lovely. I'm not always sure exactly what I'm looking at, so I may not be getting the full effect, but still the view - all 2 degrees of it in the eyepiece - was generally well worth looking at anyway. I guess it will be worth looking at these again when I'm more used to looking through the eyepiece, and at picking up details... and when there are fewer lights going on at random intervals in the house next to the 'scope (argh).

Also, saw one - possibly two - meteors. Perhaps this is just a factor of actually being out there and actually looking. I'm really looking forward to being out during a good meteor shower, now. Finished with Jupiter, again, because it's just too good to go past right now.
