Patch 0.9.8.0e

I have a question. Is it possible to integrate the ephemeris file DE431 (lnxm13000p17000.431) in SpaceEngine? And if so, how?

The asteroid '3122 Florence (1981 ET3)', for example, has this ephemeris:

planetary ephem. DE431
SB-pert. ephem. SB431-N16

Can I integrate it somehow?

Jack is this the famous double moon near earth asteroid that was just discovered?
Also thanks for the shaders file it fixed the stars and now the textures on the water are also fixed ::0

I think so. But he has not been discovered just now. He'd been known for some time. Only that he has two moons has only been discovered now.

Thanks Jack- are the orbits accurate or do we have to wait for integration into the epheremis?
Also, I was wondering if the following systems are in SE or if there is an add-on to add them.

HD 40307 / HIP 27887 6 planets (to g)

GJ180 2 planets (to c)

Rho1 Cancri 3 planets (to d)

To see if that is possible.

Also, I was wondering if the following systems are in SE or if there is an add-on to add them.

These are all three in SpaceEngine.
If you enter HD 40307 or HIP 27887 in the search window, the names are not shown in the list for any reason. But if you click Goto, you will be taken there.

GJ 180 is as Gliese 180 in SpaceEngine.

Rho1 Cancri (Rho1 Cnc) or 55 Cancri is also in SpaceEngine. But it has, according to Wikipedia, 5 planets that even have names.

Thanks it would be good to get the ephemeris for this near-earth asteroid

About the exoplanets are all the ones discovered in the above list already in SE? If the names are not listed in the search window, how does one go there? Do I enter Goto in the console? Thanks Jack!

Yes.

If the names are not listed in the search window, how does one go there? Do I enter Goto in the console?

You can enter Goto HIP 27887 or Goto HD 40307 in the console. (Instead of Goto you can also write GotoFast.)

You can also type the name in the 'Find object' window and click 'Go to'.
If the star exists, you go there, whether or not it is displayed in the list.

Thanks Jack! And all the planets are included, they just do not have the names mentioned in wiki?

I have a question. Is it possible to integrate the ephemeris file DE431 (lnxm13000p17000.431) in SpaceEngine? And if so, how?

Yes, put it to data/ephemerides/, and specify path to the file in the config. I'm not sure that SE can handle it, I never tested it with this 2.5 GB file.

The asteroid '3122 Florence (1981 ET3)', for example, has this ephemeris:

planetary ephem. DE431
SB-pert. ephem. SB431-N16

Can I integrate it somehow?

No, the lnxm13000p17000.431 file contains only ephemerides of planets.

I'm not sure that SE can handle it, I never tested it with this 2.5 GB file.

well that was fast in latest beta:

This happens only because you have the file packed. This requires 2.5 gigabytes of memory, only to open the file.
You can also directly put the file in the 'data\ephemerides' folder.

But I get this error message. regardless of whether I set 'JPLEphemeridesT' to true or false.

I suppose this is a needless question to ask since I think I already know the answer (No)- but is there a realistic way to model solar flares? Over the last week we have seen more solar activity than in a decade and have seen northern lights down to Arkansas, Alabama and Oklahoma. As a matter of fact, another solar outburst just occurred 2 hours ago! Is there a way for SE to model auroral activity in real time and display it in the program when it is actually happening and in the right locations where it is happening (depending upon the orientation of the flare with relation to the earth- and perhaps also other planets?)

Oh... and travelling at 1c is still slow given the size of the Universe. Think about it — try travelling from Earth to Proxima Centauri at 1c and it will take you a little over 4 years to get there. You need to go much faster if you want to see stars whiz by à la Star Trek.

Yeah I just select Goto and I get that whizzing effect of the warp drive that Doc was talking about.
I'm talking more along the lines of say I am orbiting a planet or flying over a planet and want to explore the terrain below me. The terrain doesn't change no matter how fast I go.

Wait a minute, that doesn't sound right... how are you changing the velocity? Mouse wheel? That just changes the acceleration you will experience once you try and change velocity with one of the keys (arrows keys, num-pad 1 & 0).

You should see two numbers next to the clock at the bottom left, the top one is actual velocity, the bottom one is your current acceleration setting.

If this is blatantly obvious, my apologies, but I can think of no other reason you can travel from star to star, or planet to planet, yet once there cannot move relative to that planet.

I am using the arrow things at the bottom and clicking on them. Am I doing it wrong? I click on the on
I am using the arrow things at the bottom and clicking on them. Am I doing it wrong? I click on the one that says Increasing Velocity. I just sit in the same location no matter how fast I make it.

And since we are on the subject of the clock, how can time be set to a particular minute and second? I can get the date and the hour but it ignores me when I try to set it to the exact minute and second.

I don't know about any arrow buttons to click on, I'm talking about the actual cursor arrow keys. Up = accelerate forward; down = decelerate, or accelerate backwards; left & right = well, left and right; numpad 1 = accelerate vertically up; numpad 0 = down; Z key will cancel all movement.

For rotation, use the numpad keys 8, 2, 4, 6, 7, and 9. The numpag 5 key will cancel all rotation.

And how these affect the camera will depend on what mode you are in. The upper row number keys 1 to 3 will change how the camera reacts. (4 is to take control of a ship.)

Hope this helps.

Edit: Oh, and if you are a "gamer", the movement keys (and some rotation keys?) are duplicated on the left side of the keyboard, but I don't use them much, so don't remember what they are. You can assign any keys of your choice from the Main menu, Settings submenu, Controls option.

I just wanted to update this. I experimented with Trappist-1e using these controls, and using the number pad I can use it for moving left-right up-down etc (though sometimes it stops working and I just drag around the window with the mouse.) I have the bottom number (acceleration) set to 10,000 km/sec but to get the top number to change (the actual velocity) I have to use the up arrow key. It doesn't give me continuous movement- all it does is give me a "boost" in speed for the time I have the up arrow key pressed and then it goes back to 0.

Incidentally, pressing "Z" doesn't do anything, but since the velocity goes right back to 0 as soon as I lift my finger off the up arrow key, it isn't needed!

Followed on the ship? I'm not sure! The other thing I was wondering about is how do you "lock on" an object. Like let's say I am viewing an eclipse at a narrow FOV, and the sun and moon drift out of the field of view is there a way to keep them centered throughout the event?
Followed around the forum! I think I've finished reading new posts, I refresh the page, then I see there are more new posts! So back in I go...

To lock onto an object, there are choices: pressing "C" will center the currently selected object, but if you are moving, it will just drift out of view again. But if you right-click on it with the mouse, the bottom option will be "Track object". That will keep it centered. Just repeat the right-click to unlock the object.

Okay so if I want to fly over a planet, I can use those arrow icons to increase the acceleration but what would I use to actually move around at that speed?
Near as I can tell, you have to use the actual arrow keys on your keyboard as I outlined above. I think a joystick and throttle will be better, but alas, I am without any at the moment.

Thanks for all the help! You've been spot on. I was just viewing an eclipse at a very narrow FOV (1 degree) and the eclipse keeps drifting from view. Would you suggest I right click and track the sun or the moon to keep it centered in this narrow FOV? I was thinking right click and track the moon because the moon is what's doing the eclipsing

Incidentally is right clicking the object and clicking track better or is using the "Track" icon at the bottom and clicking on that better? In the case of the latter do I click on the icon a second time to "untrack"?
I am stationary (top number is 0) but of course the Earth is rotating, so celestial objects appear to move (and at 1 degree FOV rather quickly!) does this mean I can still use "C" to keep it centered?

I just pressed the "1" key continuously until I reached maximum velocity and got zoomed off into outer space! In the case of each of these controls, I have to keep the key pressed to reach maximum velocity and to keep it going, otherwise it goes back to 0 (same with rotation). Is there a way to cancel my last action (Undo) and go back to where I was before the last action? Or do I have to keep saving as a favorite just before performing an action

I wish I knew how to keep continuous motion ongoing and actually see it onscreen so I could make one of those cool videos I see on here sometimes, where the person is flying between mountains and through canyons! (edit- to do this I actually had to slow down acceleration to 1000 m/sec and keep the up arrow key continuously pressed- moving too quickly- even something like 10 km/sec pressing the up arrow key continuously, flies me right off the planet!), but I still don't know how people navigate in between narrow canyons and mountain ranges to make those spectacular videos!)
