Kelso). It includes daily values of Kp indices (8 three-hour values per day), Ap indices, F10.7 solar radio flux, and other solar/geomagnetic parameters essential for: - **SGP4/SDP4 orbit propagation** — atmospheric drag modeling - **Atmospheric density models** — JB2008, NRLMSISE-00, DTM - **Conjunction screening** — collision avoidance maneuver planning - **Space weather research** — solar cycle analysis, geomagnetic storm studies ## Schema | Column | Type | |--------|------| | `date` | datetime64[us] | | `bsrn` | int64 | | `nd` | int64 | | `kp1` | float64 | | `kp2` | float64 | | `kp3` | float64 | | `kp4` | float64 | | `kp5` | float64 | | `kp6` | float64 | | `kp7` | float64 | | `kp8` | float64 | | `kp_sum` | float64 | | `ap1` | float64 | | `ap2` | float64 | | `ap3` | float64 | | `ap4` | float64 | | `ap5` | float64 | | `ap6` | float64 | | `ap7` | float64 | | `ap8` | float64 | | `ap_avg` | float64 | | `cp` | float64 | | `c9` | float64 | | `isn` | int64 | | `f10_7_obs` | float64 | | `f10_7_adj` | float64 | | `f10_7_data_type` | str | | `f10_7_obs_center81` | float64 | | `f10_7_obs_last81` | float64 | | `f10_7_adj_center81` | float64 | | `f10_7_adj_last81` | float64 | ## Quick stats - **25,245** daily records - Date range: **1957-10-01** to **2041-10-01** - **31** columns ## Usage ```python from datasets import load_dataset ds = load_dataset("juliensimon/celestrak-space-weather", split="train") df = ds.to_pandas() # Recent space weather print(df.tail(10)) # Plot F10.7 solar flux over time import matplotlib.pyplot as plt fig, ax = plt.subplots(figsize=(14, 4)) ax.plot(df["date"], df.get("f10_7_obs", df.iloc[:, -1]), linewidth=0.5) ax.set_xlabel("Date") ax.set_ylabel("F10.7 (SFU)") ax.set_title("Solar Radio Flux (F10.7)") ``` ## Update frequency Updated **daily at 12:00 UTC** via GitHub Actions. ## Data source [CelesTrak Space Data](https://celestrak.org/SpaceData/) (Dr. T.S.
