Both Aditya-L1 and Chandrayaan-2 have made observations on recent solar eruptive events and their signatures have been analysed.

On spacecraft impact:
No significant degradation in the NaVIC service, no major upsets observed in any of the 30 GEO spacecrafts. No single event upsets were seen.
Momentum Wheel speed deviations seen on some sats.
Spacecrafts with one-sided panel required frequent momentum dumping.

"The 6-meter long magnetometer boom on the Aditya-L1 satellite has been successfully deployed. It is deployed in the Halo orbit at the Lagrange point L-1, on January 11, 2024. The boom had been in stowed condition for 132 days since the Aditya-L1 launch."

"Halo-Orbit Insertion (HOI) of its solar observatory spacecraft, Aditya-L1 was accomplished at 16.00 Hrs (approx) on January 6, 2024 (IST). The final phase of the maneuver involved firing of control engines for a short duration."

Small correction for #AdityaL1 on its way.
https://www.isro.gov.in/Aditya_L1.html
"A Trajectory Correction Maneuvre (TCM), originally provisioned, was performed on October 6, 2023, for about 16 s. It was needed to correct the trajectory evaluated after tracking the Trans-Lagrangean Point 1 Insertion (TL1I) maneuvre performed on September 19, 2023. TCM ensures that the spacecraft is on its intended path towards the Halo orbit insertion around L1"

🛰️☀️ #AdityaL1, en route vers le point de Lagrange L1 Soleil-Terre, est désormais à 920 000 km de la Terre, en dehors de la sphère d’influence gravitationnelle de la Terre.
-
The #AdityaL1 mission travelled 9.2 million km. It is now said to be outside Earth's sphere of influence, as of 30 September 2023.
Aditya L1 becomes the second ISRO spacecraft after Mars Orbiter Mission to achieve this feat.

🛰️☀️ #AdityaL1 est désormais vraiment en route vers le point de Lagrange L1 Soleil-Terre ! La manœuvre d'insertion "translagrangienne" du point 1 (TL1I) a été effectuée avec succès.
L'observatoire spatial sera placé sur une orbite autour de L1 grâce à une manœuvre après environ 110 jours de croisière -
#AdityaL1 has performed the Trans L1 Injection burn successfully on 2 September 2023 at 2 am (IST).
The spacecraft is now on a 110 day journey towards the Lagrangian point L1.

After 4 orbit-raising maneuvers, the Aditya-L1 solar observatory has finally "slipped the surly bonds of Earth" and is now headed towards its destination, a halo orbit around the Sun-Earth Lagrange point L1.
ETA - about 100 days from now.https://www.isro.gov.in/Aditya_L1.html

🛰️☀️ Pour #AdityaL1, la quatrième manœuvre pour échapper à la Terre (EBN#4) a été réalisée avec succès.
La nouvelle orbite atteinte est de 256 km x 121973 km.
La prochaine manœuvre sera pour l’injection vers le point de Lagrange L1 et aura lieu le 19 septembre 2023 -
#AdityaL1 successfully completed its 4th Earth-bound Maneuver successfully.
The new orbit attained is 256 km x 121973 km.
The next maneuver is the Trans L1 Injection on September 19 at 2 am (IST).

India has launched its first spacecraft to study the Sun and space weather, called Aditya-L1. The spacecraft will orbit a point between the Earth and the Sun, where the gravitational forces are balanced. This will allow it to observe the Sun’s corona, solar flares, and coronal mass ejections, which can affect Earth's communication systems and power grids.
