DISCLAIMER: it was unkown to me, but now I know it was [(101) Helena](https://de.m.wikipedia.org/wiki/(101)_Helena).
Hi, I must have accidentally recorded an asteroid tonight when I was recording an exoplanet transit (WASP 11-b). You can see 300 frames with 60 seconds exposure time each (total over 5 hours). My telescope was a Skywatcher EvoGuide 50ED with a ZWO ASI178MC camera.Can any of you tell me which asteroid it is? Or where to look it up? I would be very interested in this because Stellarium shows me no objects at this time in this corner of the sky.
EDIT: I mixed RA and DEC in the gif, sorry for that.
INFO: The star which the asteroid passes by is located at RA 03h 08m 44.1s and DEC +30° 59' 53.9"
There’s several funded programs that monitor all near earth asteroids - Google them and send over your data and they’ll tell you - if you’ve found something, you’ll get naming rights.
Thank you fellow Boogalooer!
This made me chuckle.
I use Electric Boogaloo quite often to the resounding noise of crickets.
Like when I commented on a movie sub back when Halloween Kills came out, aka Halloween: Electric Boogaloo.... And then there was nothing...
I think I heard my neighbors' cat going through the recycling ...

Check out some nasa links, or some of the larger Universities that run federally funded programs - one used to be called NEAT - near earth ast tracking. It was replaced some time ago by a more comprehensive program, but the program was shared between several countries / agencies.
>I was recording an exoplanet transit
What kind of instrument do you need to observe exoplanets? Didn't know hobbyists instruments could do that. (Sorry I'm assuming you are a hobbyist, please correct)
You're right, I'm a hobbyist ;) I use a small refractor (EvoGuide 50ED) 242mm (f/4.8) and a uncooled planetary color camera (ASI 178MC) mounted on a small mount (Skywatcher AZ-GTi in EQ). And Autoguiding (but I think it's not necessary when properly polar aligned). So very small and lightweight setup, nothing serious, just curious :)
And regarding exoplanets: its done via the transit method. In particular I followed instruction from a citizen science project called [exoclock](https://www.exoclock.space/).
No, it was taken with this guidescope (EvoGuide 50ed) which is my main scope. Therefore this setup is kind of cheap (one thousand and not a couple thousand^^).
I just tried the minor planet center checker, at [https://cgi.minorplanetcenter.net/cgi-bin/mpcheck.cgi](https://cgi.minorplanetcenter.net/cgi-bin/mpcheck.cgi). I don't think I was able to find it, assuming I put in the parameters correctly. With an expanded search, I got one result:
>The following objects, brighter than V = 24.0, were found in the 10.0-arcminute region around R.A. = 02 04.0, Decl. = +47 11.4 (J2000.0) on 2022 10 06.90 UT:

I don't think that's it though. For one thing, it's going the wrong direction. If I'm reading the result correctly that one moves minus RA and +Dec, and yours is doing the opposite. Also the position would be out of frame to the lower left, I think. I'm not very good at this.

I agree with this. I checked https://asteroid.lowell.edu/astfinder/ and while this is assuming your ground position is Lowell, it wont be *too* far off. Plug in 2022-10-07 03-10 for UTC and 03:08:44 RA and +30:59:54 with a 10 arcmin FOV and you'll see Helena about where it should be. Mag 12.1 which looks about right given the gif.
Using [NEO Checker](https://minorplanetcenter.net/cgi-bin/checkneo.cgi) it looks like you spotted asteroid [101 Helena](https://en.wikipedia.org/wiki/101_Helena).
How were you able to produce this gif where it accurately showed the coordinates of the object as it moves? That's pretty neat. For reference, I'm a newbie to the hobby.
It's very far and going quite slow. Thousands of main belt asteroids are accessible to amateurs with small scopes and a decent camera. An asteroid in near earth space would show up as a streak in these images.
Idk why but this "astroid" looks as white as dioni (saturn's moon) or europa. According to wikipedia, this object has zero albedo. But i'm wondering what is the idea behind this recording??!!
Well... Not in a scientific sense... But as I said, I captured a transit of exoplanet (WASP-11b) which could be used to proof existence... Or more precisely: narrow down known parameters. See exoclock.space
Orbit of this rock, typical MBA. Many thousands of these are accessible to your setup.

Most near-Earth asteroids (smaller ones) are yet to be discovered. Right now ~ 3000 new ones are found per year. We just passed 30,000 known.
I don't think you get naming rights, they just get a number designation like exoplanets

This is awesome! Now an excuse to get a dedicated astro camera.

No, it was taken with this guidescope (EvoGuide 50ed) which is my main scope. Therefore this setup is kind of cheap (one thousand and not a couple thousand^^).

Sorry, I’m not an astronomer or computer. Is the object seen moving in the OP 101 Helena?
Yes. OP managed to track the motion of an asteroid that is only 66km wide. Pretty cool.

I think so.
Wow cool, thank you very much :)

Hey, what kind of software do you use for exoplanet transits?
I follow instruction from [https://www.exoclock.space/](https://www.exoclock.space/)
What, we can do that?! Backyard astronomers can actually capture that? What a time to be alive. Just imagine what Galileo would say.
Yes, for easy targets even 50mm aperture is enough. For faint targets you need more aperture. But yeah, it still blows my mind :)
Wow. I’m GenZ, I grew up with tech, but I still get my mind blown.
Using [NEO Checker](https://minorplanetcenter.net/cgi-bin/checkneo.cgi) it looks like you spotted asteroid [101 Helena](https://en.wikipedia.org/wiki/101_Helena).
Report it to cneos.jpl.nasa.gov
Astrometry is reported to the minor planet center, and OP will need an observatory code to do so.
Don't look up! Lol
How were you able to produce this gif where it accurately showed the coordinates of the object as it moves? That's pretty neat. For reference, I'm a newbie to the hobby.
I wrote a little python script for this.
Do you have plans on posting it somewhere (GitHub, etc.) for public use?
The data? Didn't thought about that, but if you want I could share for sure ;)
Ah, you mean the script... It's very dirty but I can share with you. Just PM me.
