An ISS pass is a pretty common event. Its orbit ensures that it will pass over at at pretty regular intervals. But many passes are frequently not visible or occur at low angles.
What is unique about this pass is that it is nearly overhead and occurs right around sunset. The station will be visible for a comparatively long time and will still be brilliantly illuminated in full sunlight just as we're getting dark down here on earth.
It will be a pretty spectacular sight. Just look to the northwest sky starting at 6:46pm. As it appears, it will become by far the brightest object in the sky and appear as a steadily moving bright unblinking light travelling nearly vertically across the sky. Venus might be a tad brighter, but it will be very low in the southwest sky about to set as this pass happens.
For tracking the pass in real time, I like the Heavens Above app.
As an amateur radio operator, I sometimes also like to try and communicate with the ISS during good passes like this. That station is equipped with a packet data repeater that allows for the sending and receiving of short messages, and from time to time, the astronauts themselves are even active on voice communications.
Sorry, I suck at this because I learned my constellations the old fashioned way off a paper chart with a red-light flashlight. (And I still highly recommend people learn their constellations over looking at a cell phone screen- your eyes adjust much better!)
The one I do recommend to everyone though is Sputnik! which is a free iOS app to track the space station. I'm playing around with Satellite Tracker right now to see if I like it, as it has more, but that's a subscription based one so I'm not sure yet. Otherwise, if you're not on iOS definitely get the heavens above Android app- frankly I wish they had an iOS version of that anyway as the website is great, and that's usually where I go to look up what satellite I saw!
Vista anche l'altra sera, grazie alla segnalazione di Astronomia Pratica su Twitter
Io come app uso Heavens Above, penso che sia simile alla tua
Merci tu m'as appris deux trois petites choses, c'était une lecture intéressante !
Sinon pour les applis je te recommande Heavens Above qui est un équivalent de Sky Map qui répertorie également les trajectoires des satellites et les étages de fusées dans le ciel ainsi que les horaires de passage de l'ISS.
Il y a également un peu de données scientifiques qui aident à l'observation comme l'orbite autour de la Terre, les coordonnées et la magnitude.
L'appli est moins précise que Sky Map pour s'orienter dans le ciel mais ça reste utilisable sans problème !
yeah try to gaze on new moon days or days close to new moon. apart from light pollution, moon is the biggest thing thats gonna stop u from seeing galaxies n clusters on binoculars. but even when the moon is there, u can gaze at the moon
plus u need to let ur eyes adjust to the dark (for about 20 mins) so it becomes sensitive to the weak light from the sky. even using ur phone on medium settings will ruin ur eyes sensitivity. I always used to turn on red filter for my phone n bring the brightness all the way down if I was gazing with a companion app.
ps: try looking for iridium flares if u are using binoculars. they're super predictable(but doesn't last long) and binoculars are perfect for them.
There should have been another one around that time but I think it was pretty low in the sky. The one I saw was right around 8pm EST, where it took about 6 minutes to go straight across from SW to NE. It looks pretty much like a star (no blinking) but moving like a jet.
My boss turned me onto an app called Heavens Above where you can easily track what might be above you at any given time, including the ISS.
>Korzystając z naprawdę dobrych warunków do obserwacji dzisiaj
Zazdroszczę. Nie wiem, gdzie mieszkasz, ale pozdrawiam z małopolski, gdzie spod smogu nawet słońca nie widać.
Nie mam dużego doświadczenia w obserwowaniu nieba, ale jeśli ktoś chciałby sobie ogarnąć widoczne gołym okiem satelity, flary iridium albo wiedzieć, kiedy zobaczyć ISS to polecam apkę Heavens-Above

I've heard the heavens above app is one of the better ones (you don't want a link to the app I use, it's for a windows phone, which I am almost 100% certain you don't have.) I dont' have any personal experience with the app, but just looking at the screen shots I see it's similar to the website, and the inclusion of the specific sky map is a very nice touch (the app I use, frustratingly doesn't have that feature!)
I've also always used the www.heavens-above.com website as it's pretty comprehensive and easy to use. There is a /r/heavensabove subreddit which is apparently more about the app than the website since the two stickied posts at the top are about using the app.
Download it tonight! It's a good chance to see the ISS, but I think most places in the US will dry up for ISS predictions until the beginning of September or so. But you'll always be able to catch an Iridium Flare, which is usually more impressive anyways.
I use Heavens Above for ISS and alerts for lots of other orbiting items. There is an Android app also.
And if that piques your interest for with watching generally, I can recommend Heavens Above for alerts and help spotting the International Space Station and other satellites etc.
If your in Android, this app will show you the satellite/ rocket fuel tank/ space junk passing over you. Ive spent many nights with my kids watching stuff pass overhead. It's a pretty cool feeling when you see them
Heavens Above shows you everything visible to you (satellites, ISS, booster debris, etc) at any given moment, as well as upcoming passes or events. Also gives estimations on how bright they'll be and where in the sky they'll be brightest.
Does it blink red and green? Aeroplane
Does it move up and down close to the horizon whilst standing on a beach? Ship
Does it look like a star but moves over the nightsky? Satellite
Also this might help. ;)
You could also check out this app. It is called Heavens above and has access to an extensive database of satellites and debris of which we know the orbits. It even shows you where in the sky to look to see satellites flying by. They even indicate the brightness in magnitudes (the common unit for brightness in astronomy) which is negative for very bright ones. The limit of what you can see with naked eye in the darkest areas of the earth is 6 magnitudes. So depending on where you live you might not see these faint satellites. However many satellites are very bright and can be of magnitude 1, 0 and even negative values. (Yes that is correct, the brighter the object the smaller the number).
With this info happy satellite hunting.
The Heavens Above website is great for satellite passes like Starlink and the ISS. https://heavens-above.com/
They do have an Android app but I'm not sure about iOS. I'm sure there are some good alternatives though.
The key thing with the Heavens Above site is to set your location (top right). You'll probably want to create an account so that it remembers where you are on subsequent visits. Mobile apps will use GPS to do this for you.
If you want some help on how to decipher the times, coordinates, brightness (magnitude), etc, then feel free to message me and I'll see if I can talk you through it.
You can check this app if you have Android. The app can use your GPS to show you almost the exact time and direction etc for your current location. It also shows the apparent
magnitude of the satellite (6.5 and below is visible to naked eye). Search for STARLINK-1400 and put a notification for it.
Otherwise go to this link:
Once you see one satellite, you'll start seeing satellites almost every night you go out and look up at the sky for a few minutes. I use the "Heavens Above" app to help find them. You'd be surprise by how much stuff is flying across the sky and how much of it you can plainly see with the naked eye.
Tip! Download de app Heavens Above. Daarin kan je alle satelliet passages zien. Hoe lager het getal voor de helderheid, hoe beter hij te zien is. https://play.google.com/store/apps/details?id=com.heavens_above.viewer
Managed to catch them myself.
I've seen satellites passing overhead before, but it's surreal seeing a whole string of them.
For Android users, I recommend the Heavens Above app. It shows the satellites in realtime.
Here is a short guide to Keplerian elements. This is the data that satellite prediction engines to forecast the location of satellites.
There are several phone apps that will show satellite locations. Try Heavens above if you are using Android.
>how not far the ISS is
If you've never done it, I'd highly recommend looking up your location on here, with the possible assistance of a mobile app like this or this, and going outside to see the thing fly over. All you need is a clear night, even in and around major cities. It's quite bright, and pretty easy to spot (it'll be the thing that looks like a bright star, moving at a constant and surprisingly quick rate across the sky). Blows my mind every time.
I use Heavens above
Yep on the app thing, I enjoy sitting outside looking up just about every clear night while
enjoying a "vape pen", its my happy hr instead of the bar.
Here my three favs.
Link to Google Play
I use heavens above mobile app.
Android app: https://play.google.com/store/apps/details?id=com.heavens_above.viewer
Try https://heavens-above.com/main.aspx or the app https://play.google.com/store/apps/details?id=com.heavens_above.viewer&hl=en_US
I also like the program orbitron.
Most expensive object ever made, orbiting at 17,100 mph through the thermosphere, current crew .
Heavens- above site lets us track the station in real time, set London as location here or use what3words as location, and an app for android if you're mobile.
Watch the space stations view of earth
Or use the star charts to visualise the objects real time position and trajectory relative to constellations from the ground (which seems about as unlikely as any of us Londoners getting out to space ourselves any time soon:)
Heavens Above is really cool if interested in satellites.
Do podglądanie satelit polecam Heavnes-above na androida .
At December 21st the Earth's north pole is tilted 23° degrees away from the sun, this is the point where the tilt is the furthest thus the Sun's movement will go back up again. So, around this period of time, the Sun goes down, "stops" (at the 21st), and then goes back up again, which obviously results in less declination over this period of time. This also happens on June 21st but reversed. This explains why there is more declination from Aug to Oct than Oct to Dec.
Btw, it seems like you are a programmer just as I am, and I don't think you are a scientist and neither am I. We both had to learn about space from the internet, books, etc..
But it seems like you don't believe how the solar system (and beyond that) works. That is why I ask you to actually start researching some proper material instead of searching for the denial (like this TYCHOS book).
Here is some material to get you started:
Also, I'd like to point out a few applications which use formulas created by scientists to predict where planets, stars, asteroids, meteors and (man-made) satellites are. You can check if they are right by looking up at the night sky!
And one final thing, get a telescope! I bought one myself too, and it is so much fun watching the planets, moon and other deep sky objects!
Heavens Above is good for tracking satellites, including ISS
This one is really great too for Android!
Isso não é incomum. Sugiro o Heavens Above pra saber dos próximos.
They have a very nice Android app as well.
There are many ways. NASA provides a service that will email/text you when it is going to be viewable:
ISS Detector for android is very good at notifying you and you can customize when you'll be notified (only at certain times (not too late) and only if it's bright enough (it varies in brightness depending on angle with the Sun):
Heavens Above is another one that has many more satellites you can monitor but its notification features aren't as good in my experience
They also have a website: http://heavens-above.com/
That should get you started!
EDIT: Just got an email from spot the station. If it's not raining tonight or cloudy where you are you might be able to see it cause it's gonna be overhead:
Time: Wed Jun 03 8:53 PM, Visible: 6 min, Max Height: 61 degrees, Appears: WSW, Disappears: NE
It's called heavens above. It's only for Android phones at the moment
My app of choice is Heavens-Above. They also have a great website if you wish to use that as well.
Well, you can find out where they are at any point using Heavens Above if you use Android.
I just got corrected (and rightly so), technically iridium flares only apply to a specific array of satellites that have been retired. I've been using "Iridium flare" as a catch all term for so long for all visible man made objects but I should be saying "Satellite Flare" . It's a bad habit I need to break.
But there's so many you can see, if you have android you can grab one of the sky tracker apps like Heavens Above or Satellite Tracker or ISS Detector (my personal favorite) from the app store and it'll tell you when they're going to be visible to you down to the second, tell you which direction and where to look in the sky, the duration of visibility (sometimes you'll get like an awesome one that'll last for like 30 seconds or more and streak across the whole sky!) and how bright it will be. Most of them do satellites, the ISS, the planets and other cool stuff like meteor showers and comets.
You can see stuff like this video Starlink satellites all with the naked eye! It's so freakin' cool.
Crew Dragon ist aber nicht in der App, sonder nur auf der Website https://heavens-above.com (Standort auswählen!)
Genaue Uhrzeit aller Ereignisse wird angegeben und man kann sich mit dem Handy grob zum Himmel ausrichten.
Jeg foretrækker den her: https://play.google.com/store/apps/details?id=com.heavens_above.viewer
Den har flere satellitter end bare ISS og Iridium.
Handy app for android, available on iPhone also afaik.
There is no reason to piss him of, only because he is wrong.
But if you want to help him, suggest to do some experiments together. Here are some things you could do:
And if you (or your cousin) have any questions about this, feel free to ask me, I am a physics student and arguing with flatearthers is one of my hobbies :D
Se você mora em São Paulo, tem um iridium flare amanhã (25/3 18:49:59) e outro depois de amanhã (26/3 18:43:57). Horário de Brasilia. No Rio só amanhã as 5:15 AM.
Heavens Above - Sao Paulo
Heavens Above - Rio de Janeiro
Tem o app para android. Lembrem-se que os mapas dos site são celestiais. Você tem que olhar pra cima com o tablet acima da sua cabeça e alinhar o top do tablet com o norte geográfico.
Os iridium flares são mais raros. Dá pra ver o ISS várias vezes por semana e uns 3-5 satélites a olho nu. Isso na cidade. Se você estiver no campo, acho que dá pra ver uns 15-20 por noite.
Lots of easy Sat predictions for Androids or iphones... https://play.google.com/store/apps/details?id=com.heavens_above.viewer
