Astrophysical MHD is real, but so is my anime backlog , crying like Aqua every time my simulation diverges, Research Scholar at @cessi_iiserkolJoined October 2024
the CME is expected to trigger moderate to strong geomagnetic disturbances, its effect may increase if it catches up with an earlier transient. Auroras are expected, along with minor to moderate impacts on LEO satellites and space-reliant services.
The CME is projected to reach Earth on 1 September at approximately 11:00 UT (uncertainty of plus minus 8 hours with a speed of around 822 km/s (uncertainty 600 km/s to 1200 km/s). Based on the magnetic field orientation at arrival near Earth +
|| 🚨CESSI CME ALERT || 31 AUGUST 2025 //
On 30 August the Sun launched a coronal mass ejection (CME) associated with an M2.7-class solar flare from a region near the central meridian. Our analysis indicates the CME is Earth-directed with a very high probability of impact.

AR 4197 currently possesses a "delta spot" - an area where positive- and negative-polarity umbrae are within the same penumbra. This is sometimes called a "magnetic knot" in sunspots.
You can see the delta spot indicated in this screenshot which I have annotated. This is the…
The Earth's magnetic field is an invisible protector.
A quiet and fascinating phenomenon occurs at the poles of our planet. The Earth's magnetic field, like an invisible director, directs the streams of charged particles flying from the Sun.

Multiple active regions are currently visible on the solar disk, with a few flagged as flare-productive by CESSI AI/ML flare forecasting system.
A link to India's Astronomy Mega Science Vision is below. From the translational perspective, it was important for me to ensure space weather research for 1) the benefit of humanity and 2) protection of our space reliant technologies feature prominently.

Any CME associated with a potential flare from this region would be Earth directed. A coronal hole is observed on the southern hemisphere of the west limb. This coronal hole may expand over the next week.
