What is your location?

Twisst looks up the location you have entered in your Twitter bio. When you simply fill in your geographic location, you should be fine and Twisst will start alerting you to ISS passes at that location.

Twisst sends a warning through Twitter to users if it could not geocode their location. If you receive such a message, change the location in your Twitter bio here: https://twitter.com/settings/profile

If you are not sure what locations works for Twisst, have a look at these examples.



What absolutely works best, is a combination of city and country name, such as 'Sydney, Australia', or 'Latvija, Riga'.

Country names alone are a bit generic, but locations like 'India' and 'Belgium' also seem to work well.

Place names are ok too, but only if no other place with that name exists. Vilassar de Mar is no problem, but there are about twenty different Londons in the world.

Coordinates work too, even when prefixed. Both '51.84605562,5.86992801' and 'iPhone: 51.826385,5.910294' will work fine.



Here are a few examples of locations Twisst won't be able to send out alerts for.

'Houston (that's in texas)' (just the geographic terms please)

'Earth' (a bit too generic)

'Provincie Frie' (half-complete province name)

'Central PA or Coastal DE' (too cryptic when you're not from around)

Your location can't be resolved to one set of coordinates if you string together your usual whereabouts like this: 'US, UK, EU, Asia' or 'Groningen / Den Haag'. So choose where you want to be and stay there ;-) Alternatively, you could also change your location often - Twisst will regulary look for updated locations.

There is a chance of false positives: a set of coordinates Twisst thinks is good, but which is actually wrong. An example is 'Below sealevel', which got resolved to the coordinates for Sealevel, North Carolina, USA. One Twisst follower put 'Orbiting' in his Twitter profile and ended up at Orbiting Drive in a small town in Wisconsin :-)

Another one is 'The Jungle (Northern Virginia)' which was resolved to a neighborhood called 'The Jungle' in Florida, USA . Twisst will send alerts out to these users, but the alerts they get are only accurate if that user really is there.



Until Twisst came along, it didn't really matter what you had up in your Twitter bio. These are a few of the funny locations Twisst did not quite know what to make of.

Amazing!!! A bright golden ISS passed over my location Lusaka, Zambia at about 0355hrs GMT.
I am looking forward to another pass and I wonder how many times it orbits planet earth with that seemingly high speed.

One day we all will reach the stars, some of us sooner than others...

Haha, "The Harlem Valley, NY" somehow gets resolved to South Mountain, Arizona... rather strange I suppose.

Even though my twitter account clearly shows West Cornwall, UK, you keep sending me times for Conneticut USA...not much help really!

Hi gloaab, we update everyones location in our database every day. You can check on your personal page if we have the right coordinates for you.

Oh, bummer. Thank you kindly for responding.

Hi hjertebraaten, sending your location to @twisst doesn't help - our system only looks at your profile. It will be a feature on this website to set an alternative location, so you might want to return for that. Until then, unfollowing @twisst will indeed stop the alerts.

As suggested, I sent a message with my location to @Twisst but my location is still set incorrectly with Twisst. I will not be changing my profile and I haven't heard anything back from @Twisst. If I unfollow, will it stop the alerts?

De nada Ruth, glad you like it! Gracias!

es muy emocionante observar el paso de la ISS sobre mi casa, sobre todo cuando es muy brillante. y agradecer enormemente a twisst, por las facilidades que ofrece. un saludo y muchas gracias

Hi Michael,
Thanks...I did get to see them finally :) . Getting two more chances tonight...this is so much fun! Wow, these passes tonight are not quite 2 hours apart. That's so amazing that they're out there lapping Earth in under 2 hours. So much for 80 days, huh? That's really hard to wrap my mind around :)

Yeah, contact at last! No doubt about what I saw last night...they came directly out of the NW, passed directly over and then abruptly vanished into thin air shortly thereafter...I guess because they left my "visibility" zone? Ha, wasn't expecting that at all! That was SO COOL! How many are aboard currently? Our space program has always been fascinating and amazing but it's really incredible to actually get to wait and watch them fly over :). Thanks so much for my alerts...this is great!

Brenda - watch for what looks like a bright star moving across the sky. Ignore anything that's flashing, as that will be a 'plane. The time quoted is when ISS appears above the horizon, so look in the general direction and it should appear soon after. Keep watching!

Hi tjaap! Thank you for responding. I think I may have seen it last night...I saw something :) , just not quite sure what I'm looking for yet. Really jazzed about tonight since it's so clear and the ISS will be so bright and high. Beautiful night for viewing!

Hi Brenda, a heading is in the alerts. Something like 'it comes up in West-SW'. Also, when you click on the link in the alert, you'll find it under 'Where to look'.

I go wait and watch every time I get an alert and am so anxious to see the ISS but haven't ever spotted it. Is there a way to get a compass heading direction to better pinpoint where it will cross the sky? Tonight it comes up in the North...will it be coming South or SE?

Indeed (I'm Michael, btw). Given that there must be thousands of satellites up there, I guess I was just lucky to see two (three?) different objects pass over at the same time. I only went outside because TWISST told me the ISS was about to go over on a rare clear night here in SE England. But the main thing is, I saw something. And that's better than nothing.

Michael (Mel?),
The Grace satellites would have been moving on a more or less North-South line, while the ISS would have been moving more or less West to East (usually NW to SE or SW to NE or something in between), so that seems to rule out the Grace satellites for what you saw. Very interesting and I would really like to know myself, but as you said, I think you will probably never know.

It's no help, but the satellites I saw were going in the opposite deirection to ISS, (east to west) and looking up it was as if there was about an inch worth of distance between the lights I saw, which were travelling (apparently) at the same speed. I'll probably never know what I was looking at, but at least it was pretty!

I am not with Twisst and am just commenting here. I do not think I can answer your question specifically because I do not have easy access to past events. It might be out there somewhere but I don't know where. Most of the stuff available is predictions not historiocal data. And it would not be possible for anyone to tell you without knowing exactly when and where your observation was made. Because you say that two objects were following the ISS, it's hard to tell what you mean without some objective data (e.g., an estimate of how many degrees apart they were such as the distance between Betelgeuse and Sirius, or twice the width of the Full Moon... something like that). Given that the Grace satellites are not in the same orbit as the ISS (they are in polar orbits), it is unlikely that they would appear to follow the ISS for any length of time.

The ISS is in my sky at 6pm from the Southwest moving round to the West at the rear of my house then go's down towards the Northwest with the Orian star system following but tonight there were two bright lights following the Orian system are they the Grace satellites, I'm not sure can you confirm?

Actually, the Grace satellites are several hundred kilometers apart and would not appear very close together in the sky, at least not close enough to be confused as a single object. I'm also not sure how bright they are, but I am guessing that they likely can be seen. All things considered, they likely appear as two separate points of light with one following the other at a significant distance (I'm guessing no less than about 20 degrees, depending on height and their actual separation).

Thanks for the info - very interesting!

I had a great view of ISS tonight here in Sheerness, England. It came over from the west at about 17.30, and at the same time something went over the othe way, from the east. I would have thought it was just a normal satellite, but there were two points of light, apparently travelling together. Anyone got an idea of what this might have been?

Can anybody please tell me when I can see the spacestation here in Moscow?
I thought this was easy!

@18 If you change the location in your Twitter profile, it may take up to a few days to update our system. If that's not the case, let me know through @twisst so I can have a look.

My tweets from Twisst state my location as Carmarthenshire but my Twitter profile gives my location clearly as town, England. Why???

Receiving no alerts? I thought so to. Guess it's because I (we) follow @twisst and receive notifications from twisst00 trough twisst99 randomly.

Try checking your @reply. That's where I found my alerts. And yes, there are times even there are no messages. That is when ISS is not visible when passing over.

have changed my location, still haven't received updates.
looking forward to seeing this. thanks

Just to add my voice to this request

Northern Ireland is small enough to be counted as a single location, right?

i agree, can you do this please?

Too bad you can't pick up location from iPhone Tweetdeck app. Re other Twitter clients and web interface, this doesn't work for me since I am constantly traveling and all over the place in any given week. I'm disappointed. Boo hoo.

It would be nice if we could keep our humorous and vague locations and be able to send a direct message to twisst with our real location and have it remember that.

Then if we want to update it, we just send another direct message with our new location, and it's taken care of.

Yes, coffee and chocolate..... and maybe a snuggie or two or three... : )

Please Note me when the ISS pass by me
I am so excited to try this service
and can't wait to have that notification from you
Thanks a lot man , great work

I had my location listed as "Dantooine", an homage to the false location of the Rebel base in Star Wars. After I started getting reports of ISS passes over northern Argentina, I decided to change my location to a set of latitude and longitude coordinates closer to home.
