That keplerset is likely invalid by now and it is not being updated on celestrak

(the booster 43701 keplerset is revised every day)

... it's probably on the way home.

I've been retrieving the TLE from Spacetrack each morning, and indeed it may be quite close to it's parking spot (it was not far from GEO from what I saw of the numbers). That said, it was still approaching Earth, and lower than the GEO belt, so I guess maybe another orbit at least

pe1chl · Nov 20th 2018

Any idea why celestrak does not update the TLE?

Is there some kind of agreement about that?

g7iii · Nov 20th 2018

None. To be honest, SpaceTrack may not be either. I have a script that I run once a day to get satellite TLE's of interest to me

According to today's keps, Es'Hail-2 has started slowly moving east.

I8LYL former I0LYL · Dec 19th 2018

Es'hail-2 is in slight movement towards the east. Without further corrections January 13 will be at 25° and 27 January at 26° E

Everything as expected

TOKYO, November 16, 2018 Mitsubishi Electric Corporation (TOKYO: 6503) announced today that the Es'hail-2 communications satellite built by the company launched successfully from Cape Canaveral Air Force Station in Florida, USA at 5:46 a.m. on November 16 (Japan time). The satellite separated from the launch vehicle without incident at 6:18 a.m. Following completion of in-orbit tests, the satellite is scheduled to be delivered to Doha-based Qatar Satellite Company (Es'hailSat) in January 2019.

Probable, small maneuver of the Es'hail-2 apogee engines in progress.

The satellite has moved eastwards with a slight acceleration compared to the last few days.Now: 24.6902° E

Remember the Falcon-9 that put into orbit es'hail-2?

Well, the second stage that is visible in the QO-100 DATV beacon will re-enter the atmosphere within a couple of weeks.
