button will transition from green to red, providing an immediate visual warning of
severe weather.
Pota: When this is enabled, clicking on a tree icon will display information about the POTA station.
Understanding the Analemma
If you were to record the position of the Sun at the exact same time every day for an entire year, the points would form a distinctive figure-eight pattern in the sky. This curve is called an Analemma.
Why does it form an “8”?
The shape of the analemma is caused by two primary factors of our planet’s movement:
Earth’s Axial Tilt ($23.5^\circ$): Because the Earth is tilted, the Sun appears higher in the sky during summer and lower during winter. This creates the vertical length of the figure eight.
Elliptical Orbit: Earth does not travel around the Sun in a perfect circle. Our orbital speed varies—moving faster when we are closer to the Sun and slower when farther away. This causes “Solar Time” to either lead or lag behind our consistent “Clock Time,” creating the horizontal width of the pattern.
The Equation of Time
The horizontal displacement shown in the analemma is known as the Equation of Time. It represents the difference between
Apparent Solar Time (what a sundial shows) and Mean Solar Time (what your watch shows). At different points in the year, the Sun can be up to 16 minutes “fast” or 14 minutes “slow.”
Analemma in HamVision Chrono
In our software, the analemma helps you visualize:
Solar Declination: The Sun’s latitude at noon.
Seasonal Transitions: Clearly identifying Solstices (top and bottom) and Equinoxes (near the crossing point).
Propagation Planning: Understanding solar position is key for predicting gray-line propagation and signal paths.
Box 9: Aurora 24-Hour Forecast 🌌
What it is: This panel provides a 24-hour lookahead at the likelihood of auroral
activity.
Why it matters for Hams: * VHF/UHF Fun: Strong auroras create a “radio mirror,”
allowing for Auroral Backscatter—a unique way to bounce signals o the aurora
to make distant contacts.
o HF Warning: A high aurora forecast often means HF propagation might be
disrupted or “fluttery” due to ionospheric disturbances.
Box 10: Planetary Kp Index (Scale 1–9) 📈
What it is: The “Planetary K-index” is a 3-hour average of Earth’s magnetic field
stability, measured on a scale from 0 (Quiet) to 9 (Extreme Storm).
How to read it:
o Kp 0–3: Green light! The magnetic field is stable, generally meaning great
conditions for HF DXing.
o Kp 4: “Unsettled” – you might notice some signal fading.
o Kp 5 or higher: Red light! We’ve hit “Storm” levels (G1–G5). While this is
bad for standard HF, it’s the “Magic Moment” for Aurora hunters.
Box 11: DX Cluster
The DX Cluster module provides a live feed of global station activity, allowing you to
identify active DX stations and their frequencies in near real-time.
Live Spot Activity
Real-Time Updates: The list refreshes automatically to show the most recent
“spots,” including the station’s callsign, country flag, and exact frequency (e.g.,
14.081 MHz).
Timestamping: The header displays the total number of spots and how recently
the data was updated (e.g., 20s AGO).
