≈ sea-level horizon · true-north bearings — why?
Local terrain — hills, trees, buildings — can shift the actual sunrise/sunset by a few minutes. Bearings are geographic true north: set your phone compass to True North so its reading matches (iPhone: Settings › Compass › Use True North · Android: enable true north in your compass app).
💡
Best observing window: typically mid-morning before ground heat creates atmospheric turbulence. Calculating optimal time...

Today's Active Regions — What to Point At
The most prominent active regions on the visible disc right now, ranked by area and flare potential. NOAA-classified magnetic complexity. Use these to plan your H-alpha or white light session.

Daytime Planet Visibility
Bright planets occasionally visible in daylight under exceptional conditions. Venus is most achievable; Jupiter rarely; Mercury never (too close to Sun — dangerous).
⚠️ Never sweep the sky with binoculars or scope while the Sun is up unless you have proper solar filtration — you can swing through the Sun by accident.

⚠️
One more time: Never look at the Sun through any optical instrument without a properly mounted, certified front-aperture solar filter. ND filters, exposed film, sunglasses and welder's glass below shade 14 are NOT safe. When in doubt, don't. Your eyesight is irreplaceable. Solar terms glossary →
