Sun activity for November 28, 2023: One more sun-stuff blast into space
Today’s top news: Sun activity level is low during the past day with only C flares and low flaring production. But after yesterday’s huge rope of plasma and magnetic fields, a filament, coronal mass ejection (CME) producer, the sun blasted another big burp of solar material. It occurred at around 11:58 UTC on November 27 and produced almost simultaneously forming a line of exploding filaments on the north hemisphere. Distinctively it produced a coronal mass ejections (CME) that are under modeling and analysis to determine any Earth bound component. Same as yesterday, if this CME is heading toward Earth, this could mean disturbances in Earth’s magnetic field – aka geomagnetic storms – and that would mean more auroras. Don’t put up your cameras and lenses! Auroras may return during the next days. Keep tuned.
Last 24 hours: Only eight C flares produced by the sun during the past day means sun activity is at low level within the last 24 hours (11 UTC yesterday to 11 UTC today). The largest blast was a C6.7 from AR3500 at 18:52 UTC on November 27. There is an incoming active region on northeast unnumbered yet that could be considered the lead flare producer of the period. It blasted 2 flares. The rest of the six C flares were exploded individually by different active region, one each. The sun has 10 active regions on its Earth-viewed side. Region AR3500 reduced its magnetic complexity to a beta-gamma configuration, the same as AR3499. The rest of the active regions show alpha and beta configurations.
Next 24 hours: Today’s forecast is a 95% chance for C flares, a 35% chance for M flares, and a 5% chance for X flares.
Next expected CME: The filament eruption at 6 UTC on November 27 we reported yesterday, after modeling and analysis, the resulting coronal mass ejection (CME) was found a component south of Earth’s orbit. A glancing blow will reach us on November 30. There is one more emission of sun-stuff that may come similar as the one just mentioned, southerly bound to Earth’s orbit. It was observed in LASCO C2 imagery at 20 UTC on November 27 and is associated with the C3.8 flare at 18:37 UTC on November 27. Analysis and modeling of this event continue. We will report the results as soon specialist come out with final conclusion.
Current geomagnetic activity: The geomagnetic field is quiet at the time of this writing (11 UTC on November 28). Quiet to unsettled conditions are expected over the rest of the day and tomorrow as the effects of CME impact and high-speed solar wind from a coronal hole wane but an increase of geomagnetic activity is anticipated by November 29, late, as the glancing effects of the CME hurled by the sun on November 27 will start to provide its effects.G1 (minor) geomagnetic storm is possible with chances for a G2 (moderate) storming. Alert for aurora chasers.

We invite you all to send us your beautiful recent photos of sunspots and auroras. Naturally, we love receiving your photos! And to those of you who’ve already posted a photo to our community page, thank you.
Bottom line: Sun activity for November 27 is low. A blast of solar material may be heading our way and that could mean more auroras!
