How far the aurora reaches Nova Olinda
- Geomagnetic latitude
- 0.8° N
- Geographic 7.6° S
- Kp needed to reach here
- only exceptional storms (beyond the usual Kp 9 line)
- Low on the northern horizon first; overhead takes more
- Tonight's line
- 63.8° · 63.0° short
- At Kp 1.3 (NOAA, 21:00 UTC)
Geomagnetic latitude, not geographic, decides how often aurora is seen: Earth's magnetic poles are offset from the geographic ones. Approximate (centered-dipole model, typically within a few degrees); clouds, darkness and moonlight still decide what you see. See the live map and NOAA viewlines for both hemispheres.

Where can you see the aurora right now?
Live NOAA auroral-oval data shows how far south the aurora is currently reaching.
The aurora is currently too far north
📍 Nova Olinda, Tocantins, Brazil · Current Kp: 1.3
Aurora is very unlikely at your latitude — even the strongest storms rarely reach this close to the equator.
Current visibility line: ~3876 mi north of you.
Kp measures the disturbance of Earth's magnetic field. Higher Kp generally pushes the auroral oval farther toward lower latitudes.
What this means for Nova Olinda, Tocantins, Brazil
Right now, the auroral oval is too far toward the pole to make the aurora likely from Nova Olinda, Tocantins, Brazil. A stronger geomagnetic storm would be needed for the aurora to reach this far north.
What else matters
Geographic auroral activity isn't the same as visible aurora — you also need dark skies and clear weather.

Nova Olinda, Tocantins, Brazil sits at about 0.9°N geomagnetic latitude. NOAA's scale lists 40° (a Kp 9, G5 storm) as the lowest latitude where aurora is typically seen, so sightings here are very rare.
Aurora is usually most active in the hours around local magnetic midnight, which for most places is within a few hours of local midnight. Geomagnetic storms are also more frequent around the March and September equinoxes (the Russell–McPherron effect), which is why those months are listed above, provided the sky gets properly dark.
Month-by-month darkness and Moon

| January | 9.0 h | 32% | — |
| February | 9.3 h | 36% | — |
| March | 9.5 h | 32% | Equinox |
| April | 9.7 h | 30% | Equinox |

| November | 9.1 h | 33% | — |
| December | 8.9 h | 35% | — |
Darkness = hours with the Sun more than 18° below the horizon on the 15th. Dim Moon = share of nights in 2026 when the Moon is under 25% lit at local solar midnight.
How often each storm level happens (NOAA)

Tonight's Sky Over Nova Olinda, Tocantins, Brazil
Right now, skywatchers near Nova Olinda, Tocantins, Brazil are tracking real-time space weather conditions overhead.
Current Environmental Conditions
The current planetary Kp index reads 1.3, with real-time cloud cover at 3% and the Moon at 6% illumination (Waxing Crescent).
Local Forecast Summary
Of the next 48 hours in the live forecast, 26 show cloud cover under 30% — a generally favorable stretch for clear-sky viewing.
Why This Happens
With Kp currently at 1.3, Earth's magnetosphere is in a relatively calm state — the aurora oval sits closer to the poles than it does during active storms.
Observation & Gear Tips
With skies this clear, a wide-field lens or naked-eye viewing will capture more of the sky than a narrow, high-magnification setup.
