  CoRoT was the first space mission dedicated to exoplanet detection.
Operational between 2007 and 2012, this mission discovered 37 transiting
planets, including CoRoT-7b, the first terrestrial exoplanet with a measured
size. The precision of the published transit ephemeris of most of these planets
has been limited by the relative short durations of the CoRoT pointings, which
implied a danger that the transits will become unobservable within a few years
due to the uncertainty of their future transit epochs. Ground-based follow-up
observations of the majority of the CoRoT planets have been published in recent
years. Between Dec. 2018 and Jan. 2021, the TESS mission in its sectors 6 and
33 re-observed those CoRoT fields that pointed towards the Galactic
anti-center. These data permitted the identification of transits from nine of
the CoRoT planets, and the derivation of precise new transit epochs. The main
motivation of this study has been to derive precise new ephemerides of the
CoRoT planets, in order to keep these planets' transits observable for future
generations of telescopes. The TESS data were analyzed for the presence of
transits and the epochs of these re-observed transits were measured. The
original CoRoT epochs, epochs from ground-based follow-up observations and
those from TESS were collected. From these data updated ephemerides are
presented for nine transiting planets discovered by the CoRoT mission in its
fields pointing towards the Galactic anti-center. In three cases (CoRoT-4b, 19b
and 20b), transits that would have been lost for ground observations, due to
the large uncertainty in the previous ephemeris, have been recovered. The
updated ephemerides permit transit predictions with uncertainties of less than
30 min for observations at least until the year 2030. No significant transit
timing variations were found in these systems.
