Clouds all night.

5 p.m.9 p.m.midnight3 a.m.6:54 a.m.
Sunset 5 p.m., sunrise 6:54 a.m. Fully dark from 6:38 p.m. to 5:16 a.m. Cloud (Euro, the larger of its total and highest layer): 7 p.m. 100%, 9 p.m. 100%, 11 p.m. 100%, 1 a.m. 100%, 3 a.m. 100%, 5 a.m. 100%. The moon, 30% lit, rises at 1:54 a.m.
Fully dark The sun 18° or more below the horizon, past astronomical twilight: its scattered light is fainter than starlight and other natural light. U.S. Naval ObservatoryTotal, high, middle and low: cloud cover (darker: more)Moon: its height in the sky, shaded by how much is lit
How to read the strip
The strip runs from sunset to sunrise: twilight (civil, nautical, then astronomical, the sun 6°, 12° and 18° down), then full dark. Clouds are the Euro model's total, high, middle and low cloud for each hour; the model runs every 3 hours here, 6 hours after 6 days, and Open-Meteo fills the hours between. The moon is drawn by its height above the horizon, shaded by the share of it lit. A smoke row shows when the PM2.5 forecast (Copernicus CAMS, through Open-Meteo) reaches 35.5 µg/m³, the bottom of the EPA's "unhealthy for sensitive groups" range: smoke may dim the sky. (The home page's air badge, which is about health, starts at the EPA's Moderate level, 9.1.)
Golden hour 4:18 to 5 p.m. (sunset); 6:54 to 7:36 a.m. (sunrise)
Blue hour 5:18 to 5:42 p.m.; 6:12 to 6:36 a.m.
Fully dark 6:38 p.m. to 5:16 a.m.
Lens Dew likely on the lens: low 49°, Dew point The temperature air must cool to before it is saturated. A higher dew point means more moisture in the air. National Weather Service glossary 49° (NWS)

Planets tonight
Three of the five bright planets are up tonight: Mars, Jupiter and Saturn.
MarsMagnitude How bright a star or planet looks in our sky. The scale runs backward: lower is brighter, and 5 steps is 100 times the light. NASA Marshall Space Flight Center 0.8Rises 11:42 p.m.; still up at sunrise.Climbing all night: 61° up in the south by 6:24 a.m.
Jupitermagnitude −1.9Rises 12:09 a.m.; still up at sunrise.Climbing all night: 58° up in the south by 6:24 a.m.
Saturnmagnitude 0.5Up at sunset; sets 4:04 a.m.Highest at 10 p.m.: 47° up in the south.
Too low to see tonight: Mercury and Venus (never 10° up between dusk and dawn).
Close together tonight: Mars and Jupiter, 4.5° apart at 6:24 a.m.
The planet hours tonight: 5:30 p.m. to 6:24 a.m. Computed here with PyEphem.
Space station
ISS orbit updated Nov. 2, 4:25 a.m.
The station makes two visible passes from tonight through Tuesday night, Nov. 10; the next is Wednesday, Nov. 4, at 5 a.m.
Wednesday, Nov. 4, 5 a.m.for 1 minute, magnitude −1.2From the south to the south; highest 13° up in the south at 5 a.m.Comes out of Earth's shadow 13° up in the south.Clouds then (Euro): 100%.
Tuesday, Nov. 10, 6:31 p.m.for 2 minutes, magnitude −1.9From the south to the south-southeast; highest 18° up in the south-southeast at 6:32 p.m.Fades into Earth's shadow 18° up in the south-southeast.Clouds then (Euro): 10%.
The International Space Station's orbit: Celestrak; computed here.
Aurora
SWPC updated 6:30 a.m.
NOAA Space Weather Prediction Center
Quiet. SWPC forecasts Kp A 0 to 9 index of how disturbed Earth's magnetic field is; 5 or more is a geomagnetic storm. NOAA Space Weather Prediction Center 2 at most tonight; Faribault needs about 7.
Solar wind The flow of particles and magnetic fields outward from the sun, typically near 350 km/s. National Weather Service glossary 342 km/s (765,000 mph); Bz The north-south direction of the interplanetary magnetic field. When it points south, opposite Earth's field, geomagnetic disturbances are much more severe. NOAA Space Weather Prediction Center glossary −3 nT, south, which favors aurora (12:30 p.m.)
Kp now 0, SWPC's estimate (12:29 p.m.)
OVATION The model behind SWPC's aurora forecast: where the aurora will be and how strong, 30 to 90 minutes ahead. NOAA Space Weather Prediction Center 0% chance of aurora overhead here, and at most 0% within 6° of latitude to the north (12:28 p.m.)
Kp through Thursday: highest 3.67, Thursday midnight to 3 a.m.

Moon
Computed here
The moon, 30% lit, rises at 1:54 a.m.
Waning crescent, 30% lit
Next moonset 2:25 p.m. today; next moonrise 1:54 a.m. Wednesday.
Next full moon Tuesday, Nov. 24, at 8:53 a.m.: the Beaver Moon. A supermoon: it is 97% of the way from its orbit's farthest point to its nearest, and NASA's definition takes 90% or more.
The moon, 53% lit, is up 6 of the 11 dark hours; moonlight will cut how many meteors you see.
The Radiant The point in the sky that a shower's meteors seem to come from. International Meteor Organization glossary rises at 11:04 p.m. and is highest, 68° up, at 6:34 a.m.
Best hours: 2 to 5:32 a.m.
The cloud forecast for these hours shows up here 7 days before the night.
The ZHR The number of a shower's meteors one observer would see in an hour with the radiant overhead and stars to magnitude 6.5 visible. International Meteor Organization glossary is a best case; real counts here will be lower.

The aurora log
Kp record updated 6:22 a.m.
Kp since 1932: GFZ Potsdam
Kp 7 or more on 387 nights since 1932; 35 of them since 1993 were clear here.
KFBL's reports settle 73 of the 85 nights since 1993; the rest have an hour with no report. The last clear Kp 7 night here was July 3-4, 2026 (Kp 7).
The log lists Kp and what the airport reported for the sky. It never says anyone saw an aurora.

The aurora log: a night counts when a 3-hour Kp of 7 or more (GFZ Potsdam's record, since 1932) falls in its fully dark hours. Since 1993 it is clear here when every report from the Faribault airport (KFBL) in those hours lists only clear skies or a few clouds, with a report in each full clock hour of them; any scattered, broken or overcast layer makes it "cloud reported", and a full hour with no report "no full record". The airport's sensor reports the clouds it can measure, so high thin cloud may not show.
