Aurora visibility threshold for Changchun. At a geomagnetic latitude of 34.9°, the minimum Kp giving a realistic chance of visible auroras above Changchun is about Kp ≥ 9. The current equatorial Dst index is 0 nT — the magnetosphere is in a quiet phase. Dst complements Kp by showing how long and how deep a storm's main phase has been — useful context when checking whether auroras are likely tonight.

Weather and atmospheric pressure in Changchun right now. Temperature +21.3°C, atmospheric pressure 736.8 mm Hg (982.3 hPa), cloud cover 63%, humidity 41%, wind 20.5 km/h. During G1+ geomagnetic storms, swings in atmospheric pressure tend to amplify symptoms for weather-sensitive people: those with hypertension often notice blood-pressure spikes, and readings below 1000 hPa combined with Kp ≥ 5 frequently bring headaches and fatigue. That is why the Changchun page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
