What\u2019s coming up in the northern hemisphere\u2019s night sky in the week of 11th to 17th July.<\/p>\n\n

Transcript<\/h1>\n
Ezzy Pearson <\/strong>Greetings listeners and welcome to Start Diary, a weekly guide to the best things to see in the Northern Hemisphere\u2019s Night Sky. In this episode, we\u2019ll be covering the coming week from the 11th to the 17th\u00a0 July. I\u2019m Ezzy Pearson, the magazine\u2019s news editor. And I\u2019m joined on the podcast today by reviews editor Paul Money. Hello, Paul.<\/p>\n
Paul Money <\/strong>Now then, as a how are we doing?<\/p>\n
Ezzy Pearson <\/strong>I\u2019m doing well. But let us know what your recommendations are for the coming week\u2019s night Sky.<\/p>\n
Paul Money <\/strong>Well, last week we did mention the moon. And when it\u2019s in the evening sky, it is the obvious object to actually observe. But on the 13th, it\u2019s full. Now, yes. Deep sky observers. Sorry, but the moon\u2019s full but it is light nights, so. So you\u2019re not exactly going to be seeing much in the way of deep sky. I always think Deep Sky is a case of what you call deep sky, Double stars. They don\u2019t need very dark skies sort of thing. So they\u2019re well worth looking at. And the moon doesn\u2019t need dark skies, does it? Sort of thing. And when it\u2019s full this is your chance to pick out a lot of the ray features. Now, we did mention that the Rays of Copernicus<\/a> were beginning to appear last week as the Terminator was sweeping across Mare Imbrium and Copernicus hadn\u2019t quite appeared into the daylight on the moon\u2019s surface. Well, now it has. When we\u2019re full, we get a chance to see the Rays. Now a lot of people go for the most popular ones, and that has of course the typical Tycho<\/a>, Copernicus<\/a>, Kepler, Aristarchus. By the way, if you\u2019re Aristarchus, have a little side note sort of thing and look out for Schroter\u2019s Valley nearby. I mean, it\u2019s winding a ways. It\u2019s actually one of the most obvious valleys, I think more obvious really than Hadley Rille. Hadley really takes a little bit more observing skill to actually pick out. But Schroter\u2019s Valley definitely a lot easier, but there are a few others as well, and it\u2019s worth having a look out on the sky sort of thing to on the moon to actually see these and I always think Messier twin streaks, so I mean, messier isn\u2019t deep sky objects alone. There is a crater Messier actually on the moon as well in mare Fecunditatis. So have a look at the two\u2026 It\u2019s very strange because it\u2019s the only one I know that\u2019s got twin streaks coming out of it, so there are others as well because I say the obvious ones, we always go for them. But there\u2019s Menelaus. There\u2019s some streaks coming out from that and Aristillus as well. So, you know, there are other subtle ray features, but they take a little bit more careful observation, working out where they are and then following those streaks. There\u2019s several streaks over Oceanus Procellarum as well, and they\u2019re coming from a crater. I\u2019m not sure which crater I have to say because it\u2019s on the lunar limb. Very difficult to see which crater it is. But so perhaps our listeners would like to pop in. Even I readers, sort of thing, when they get the magazine, might want to comment on that and see if they\u2019ve seen these faint rays crossing Oceanus Procellarum from the right on the limb. So I\u2019d like to know which one it is. I\u2019m not a big lunar observer, so that\u2019s something. I\u2019ve only spotted them a few times, so I\u2019ve never really paid a lot of attention. But somebody thought, why not have a look? I can do something different out of your normal routine sort of thing. So this is the time to do it. This is when the ray features are really at their best. I would say don\u2019t just stick to the main obvious one. There are a few others as well. When we get to July the 16th, now the moon, this is the interesting thing is the moon is below Saturn. Yes, Saturn is in the evening sky now. It\u2019s actually rising around about 11:00 ish. In fact, just before 11:00. So by midnight on the 16th, it\u2019s actually a well above the horizon. It finds it almost above due south east. So we\u2019ve got in actual fact, Saturn. But Saturn also formed a bit of a triangle with two of the stars in Capricornus. So it\u2019s above delta Capricorni and forming a triangle with Gamma Capricorni as well, which is just to the right of them. So you\u2019ve got this lovely little triangle of Saturn and these two other stars and then hanging below them, we\u2019ve actually got the moon as well sort of thing. So this is the 16th, so around about two or three days after full moon to look over towards the east as well. Because if you got Saturn and the moon at about midnight, incredibly, Jupiter is just rising. Now we haven\u2019t yet reached oppositions. We\u2019re going to get to them later on in the year. But it just shows you that they are becoming better placed to observe and that it won\u2019t be long before they\u2019re even the evening sky. A lot easier to observe. And to be fair, more people will look out for them. Because let\u2019s face it, when things are in the evening sky and especially the early evening skies you get towards the end of the year, then a lot more people tend to notice these planets and the moon, etc. So these are for the dedicated astronomer. Those of us who like to get will stay up late and observe these things. So ironically, the minor world Vesta<\/a> is also up because it\u2019s in Aquarius as well. So we\u2019ve got a few of the planets that we usually class in the morning parade. They are now beginning to creep into the evening sky, but late evening sky. So just before midnight. Now, I mentioned Vesta because on July 17th and we\u2019re looking around about ironically 17 minutes past midnight. So on the 17th, there we are. So Vesta is now easier to spot and it is actually around about magnitude 7.4. So, you know, it\u2019s well worth having a go at Vesta because binoculars will actually show it. But the moon is nearby on the 17th, in fact its to the left of Vesta. But there\u2019s a bit more to it, because as the moon rises, this is why I mention it, at 17 minutes past midnight on the 17th, the moon will be well up and you\u2019ll see a star to the right. We\u2019ll start earlier. Keep a lookout on the horizon and watch the moon rise because the moon is occulting this star and this star is Tau Aquarius. So it\u2019s being occulted. So we don\u2019t see the start, which would have been on the bright limb anyway, is always a lot harder to view that, but it\u2019s always easier to see the sudden reappearance of the star. And it can be quite startling because one minute you\u2019ve got this dark limb, you can just probably see a little bit, probably not a gibbous moon. So there\u2019s very little earthshine, but with a telescope you might get a hint of something, but it\u2019s basically the dark side. And then suddenly this dot light appears on the edge. And is that instantaneous? Because the stars are pinpoints of light to us. Unless they\u2019re doubles, it has some doubles were discovered Ezzy, whereby an the occultation took place. Suddenly one saw a bit and then the next. And they suddenly rise. It wasn\u2019t a single event. There was actually two. So there is Tau Aquarii appearing from behind the Moon and to the left of Vesta, so you can use Tau as a guide to Vesta itself, and so can find a minor planet, you\u2019ve got the moon, the two solar system objects and of course a star, which is an Aquarius as well. So there we are by 17 minutes past midnight. It will definitely be visible that star. But keep watching from when it rises. The moon rises and you\u2019ll see the reappearance of Tau Aquarii. So I always love these this sudden apparent sort of thing, these stars. And they, you know, that they can be quite startling, to be fair, you know, because it is such an abruptness to it. But you\u2019ve got this dark space. And then suddenly \u2018bing\u2019 there is it\u2019s in view. The only time it\u2019s different is when it\u2019s greys in the north or southern horizon of the moon, you get a graze in occultation. And then I\u2019ve only seen a couple because its usually cloudy with the rest. Wherever these events are happening its cloudy isn\u2019t it? But hopefully we have clear skies. But it\u2019s quite something to see the star flit in and out, pruning the valleys of the moon brace as you get this star flickering and what you\u2019re really seeing is the mountains. The moon\u2019s getting in the way and block it, occulting the star briefly. But that won\u2019t happen this time. But yeah, there are various occultations and great occultations throughout the year because the moon course goes around the whole of the earth and a month and throughout the year, you know, we see a whole range of different stars nearby to the moon and some occulted as well. So there we\u2019ll finish the week with an occultation, but the reappearance of Tau Aquarian.<\/p>\n
Ezzy Pearson <\/strong>That does sound like a particularly striking event to end this week on. So thank you very much for taking the time today, Paul, to tell us all about what we can see this week on the night sky.<\/p>\n
Paul Money <\/strong>My pleasure.<\/p>\n
