Unknown Satellite (camera for videometeor recording) - help?

Satellites & Observations
1

Since 25/12/2024, I have been registering a satellite (?) on cameras designed for observing meteors, the number of recordings reaches 200 per night. A very small angular velocity is typical (and high apparent magnitude), the object moves towards the south on individual nights. I am attaching measurements from one station and also a stacked photo from the whole night. This field is out of my area of ​​expertise, but I would like to know what I have to delete from the cameras every night :slight_smile: Thanks in advance for your help…

Hi,

I converted your coordinates to IOD lines, and added your locations to my sites.txt. I used the first and last observation only, because these have 3 points. IOD lines:

s1.dat:
90000 24 001A   9920 E 20241226212625000 17 25 0437804-064099 37 S
90000 24 001A   9920 E 20241226214523000 17 25 0456093-055947 37 S
90000 24 001A   9920 E 20241227023244000 17 25 0937219+011561 37 S

s2.dat:
90000 24 001A   9922 E 20241226212625000 17 25 0437587-064132 37 S
90000 24 001A   9922 E 20241226214523000 17 25 0456060-060057 37 S
90000 24 001A   9922 E 20241227023244000 17 25 0937259+011452 37 S

Next I ran satfit of sattools GitHub - cbassa/sattools: Satellite Tracking Toolkit to identify it and both observations find 26666 as best match:

NORAD  diff MA  diff RAAN   RMS      file    TLE AGE
26666   -0.022   -0.004    0.014    s1.dat   -1.016
26666   -0.030   -0.002    0.015    s3.dat   -1.016

And 26666 is Turksat 2A:

0 TURKSAT 2A
1 26666U 01002A   24362.88819634 -.00000139  00000-0  00000-0 0  9997
2 26666   7.6342  67.1611 0008300 284.3549  70.4576  0.98209607 87014

Nice picture! :slight_smile:

Best regards,

Eelke.

That’s a defunct geostationary satellite in a graveyard orbit.
