How far the aurora reaches Mogi das Cruzes
- Geomagnetic latitude
- 15.2° S
- Geographic 23.5° S
- Kp needed to reach here
- only exceptional storms (beyond the usual Kp 9 line)
- Low on the southern horizon first; overhead takes more
- Tonight's line
- 65.2° · 49.9° short
- At Kp 0.7 (NOAA, 12:00 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.
Aurora Visibility Score
Mogi das Cruzes, São Paulo
At Kp 0.7 the aurora is not expected to reach this latitude, so clear skies and darkness cannot make tonight a good night. The score is held to 15 or less.

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
📍 Mogi das Cruzes, São Paulo, Brazil · Current Kp: 0.7
Aurora is very unlikely at your latitude — even the strongest storms rarely reach this close to the equator.
Current visibility line: ~2873 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 Mogi das Cruzes, São Paulo, Brazil
Right now, the auroral oval is too far toward the pole to make the aurora likely from Mogi das Cruzes, São Paulo, 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.

Mogi das Cruzes, São Paulo, Brazil sits at about 15.1°S 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 | 7.7 h | 32% | — |
| February | 8.4 h | 36% | — |

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.

Sources: NOAA SWPC Space Weather Scales (storm levels, latitudes and frequency); IGRF-13 geomagnetic pole; Moon and Sun positions calculated on this site. The Kp-needed figure below Kp 6 is an approximation. Storm counts are long-term averages that cluster around solar maximum, so any single year can differ a lot.

How the Aurora Visibility Score works and where the data comes from
The score (0-100) adds five factors: aurora strength 40%, cloud cover tonight 25%, darkness 15%, Moon phase 10% and the place's latitude 10%. Aurora strength compares this place with tonight's viewline from NOAA's Kp table, both in geomagnetic latitude, the same line shown in "How far the aurora reaches". Cloud, darkness and moon use the dark hours of tonight in this place's own time zone.
Two limits keep it honest: when the aurora is not expected to reach this latitude, or tonight is almost fully overcast, the score is capped below "Marginal"; and sky conditions can lift it at most 15 points above the aurora factor. It is a planning guide, not a promise: the real oval, local light pollution and the Moon's altitude are not modeled.

Tonight's Sky Over Mogi das Cruzes, São Paulo, Brazil
Mogi das Cruzes, São Paulo, Brazil's current space weather picture, updated from real NOAA and Open-Meteo data.
Current Environmental Conditions
The current planetary Kp index reads 0.7, with real-time cloud cover at 99% and the Moon at 13% illumination (Waning Crescent).
Local Forecast Summary
Of the next 72 hours in the live forecast, 0 show cloud cover under 30% — a mixed outlook, so it's worth checking back closer to your viewing window.
Why This Happens
With Kp currently at 0.7, 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 cloud cover this high, a higher-elevation spot outside the local cloud deck — or simply waiting for a clearer night — will make a real difference.
