☀️ Scientists using the @NSF Inouye Solar Telescope captured the sharpest view of solar flare “ribbons.” They saw tiny, dynamic hot spots—“ribbon blobs”—that show how magnetic fields snap & reconnect, giving clues to flares & better space weather forecasts https://t.co/oVJmYrCXJH

A recent study using data from @NSF Inouye Solar Telescope documents the unprecedented rotation of two small, dark features on the Sun's surface, known as pores, which are very small sunspots and appear to be linked to a less powerful C-class solar flare: https://t.co/To9VIqKC7y

Flare update!

The biggest flare (X8.79) in solar cycle 25 from active region 3664 !!!

[IIAstrophysics @IIABengaluru]

Intense aurorae were seen at latitudes as low as Ladakh this morning due to the strongest solar storm in 2 decades. And our cameras captured its glory!

Aditya-L1 has successfully entered the Halo orbit around the L1 point! 👏👏

[ISRO @isro]

Aditya-L1 Mission:
The SUIT payload captures full-disk images of the Sun in near ultraviolet wavelengths

The images include the first-ever full-disk representations of the Sun in wavelengths ranging from 200 to 400 nm.

They provide pioneering insights into the intricate details of the Sun's photosphere and chromosphere.

Aditya-L1 Mission:

The Solar Wind Ion Spectrometer (SWIS), the second instrument in the Aditya Solar wind Particle Experiment (ASPEX) payload is operational.

The histogram illustrates the energy variations in proton and alpha particle counts captured by SWIS over 2-days.

Aditya-L1 Mission:
HEL1OS captures first High-Energy X-ray glimpse of Solar Flares

🔸During its first observation period from approximately 12:00 to 22:00 UT on October 29, 2023, the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) on board Aditya-L1 has recorded the impulsive phase of solar flares.
The recorded data is consistent with the X-ray light curves provided by NOAA's GOES.

🔸Commissioned on October 27, 2023, HEL1OS is currently undergoing fine-tuning of thresholds and calibration operations. The instrument is set to monitor the Sun's high-energy X-ray activity with fast timing and high-resolution spectra.
🔸HEL1OS data enables researchers to study explosive energy release and electron acceleration during impulsive phases of solar flares.

HEL1OS was developed by the Space Astronomy Group of the U. R. Rao Satellite Centre, ISRO, Bengaluru. More:

Aditya-L1 off to Sun-Earth L1 point!👏👏👏

[ISRO @isro]

Aditya-L1 Mission:
Off to Sun-Earth L1 point!

The Trans-Lagrangean Point 1 Insertion (TL1I) maneuvre is performed successfully.

The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point. It will be injected into an orbit around L1 through a maneuver after about 110 days.

This is the fifth consecutive time ISRO has successfully transferred an object on a trajectory toward another celestial body or location in space.

[ISRO @isro]

Aditya-L1 Mission:
Aditya-L1 has commenced collecting scientific data.

The sensors of the STEPS instrument have begun measuring supra-thermal and energetic ions and electrons at distances greater than 50,000 km from Earth.

This data helps scientists analyze the behaviour of particles surrounding Earth.

The figure displays variations in the energetic particle environment, collected by one of the units.
