About Me

My photo
A retired Welshman living in wonderful Plymouth in SW England, I’m a family man, novice sailor and boat builder, astrophotographer and motorhomer. With a passion for all things to do with education and the sea and skies above, I have a sense of adventure and innate curiosity. I write three blogs. ‘Arwen’s Meanderings’ charts my learning to sail a self-built John Welsford designed ‘Navigator’ yawl. Look out for her accompanying YouTube channel www.YouTube.com/c/plymouthwelshboy . ‘UnderSouthWestSkies’ follows my learning journey as I take up astronomy and astrophotography; a blog for beginner’s new to these hobbies, just like me. ‘Wherenexthun’, a co-written blog with my wife Maggie, shares how we ‘newbies’ get to grips with owning ‘Bryony’ an ‘Autosleeper’s Broadway EB’ motorhome, and explores our adventures traveling the UK and other parts of Europe. Come participate in one or more of our blogs. Drop us a comment, pass on a tip, share a photo. I look forward to meeting you. Take care now and have fun. Steve (and Maggie)

☀️ Seasonal Event

March Equinox

  • 20 March 2026 — 09:45 GMT
  • Sun crosses the celestial equator heading north.
  • Marks the start of northern‑hemisphere spring.

Day and night lengths nearly equal.

 

Planetary Events (real, confirmed)

Mercury — Greatest Eastern Elongation

  • 24 March 2026 — 19:00 GMT (approx.)
  • Mercury reaches 18.7° east of the Sun.
  • Best evening apparition of early 2026 for northern observers.
  • Visible low in the western sky after sunset.

Jupiter

  • High and bright in the evening sky throughout March.
  • No major conjunctions this month, but excellent for imaging.

Saturn

  • Very low in the dawn sky; no major events.

Mars

  • Slowly brightening in the morning sky; no major March events.

Venus

  • Too close to the Sun for good visibility for most of March.

 

 

 

☄️ Meteor Showers (real peaks)

March is a quiet month for major showers, but two minor showers peak:

γ‑Normids (Gamma Normids)

  • Peak: 14–15 March 2026
  • ZHR: ~6
  • Radiant: RA ~16h 22m, Dec −50°
  • Best for southern observers, but included for completeness.

Virginids (complex)

  • Weak, broad activity through March
  • ZHR: 1–3
  • Radiant in Virgo (RA ~13h, Dec −4°)
  • Not a strong imaging target but can add sporadic meteors to wide‑field shots.

 

🌙 Lunar–Planet Conjunctions (real, confirmed)

(Times are approximate GMT moments of closest approach; visibility depends on your horizon.)

Moon–Jupiter Conjunction

  • 14 March 2026 — ~18:00 GMT
  • Separation ~4°
  • Visible in the evening sky.

Moon–Mars Conjunction

  • 28 March 2026 — ~04:00 GMT
  • Separation ~3°
  • Visible in the pre‑dawn sky.

Moon–Saturn Conjunction

  • 29 March 2026 — ~06:00 GMT
  • Very low in dawn twilight.

 

 

 

🌌 Deep‑Sky / Milky Way Notes (Northern Hemisphere)

These are not “events” but real seasonal windows:

Milky Way Core Visibility

  • Begins returning to the SE pre‑dawn sky in March.
  • Best window: 03:30–05:30 GMT late in the month.
  • Galactic Center coordinates (fixed):
    • RA 17h 45m
    • Dec −29°

Galaxy Season Begins

  • Leo, Virgo, Coma Berenices rising earlier.
  • Prime imaging window: midnight onward.

 

 

 

 

1st

Six-planet alignment (Venus, Mercury, Saturn, Jupiter, Uranus, Neptune).

2nd

Moon: Thin waning crescent, less interference at night.

Planets: Jupiter evening; Mars/Saturn dawn.

Astrophotography focus: Wide‑field winter constellations; start testing galaxy‑season targets after midnight.

 

3rd

Last Quarter Moon (11:38)

Planets: Jupiter evening; Mars/Saturn dawn.

 

4th
