Quadrantids Meteor Shower
Avoid using binoculars; you'll want the widest field of view (your naked eyes) to catch fast streaks. While Jamul has some skyglow, the moderate Class 5 conditions at Palomar Observatory are still excellent for the brightest phases of this event. Look for the crisp windows between winter storms when the air is scrubbed of all dust and haze. A drive out of Jamul toward Palomar Observatory will significantly improve your chances of spotting the fainter details of this event.
Optimal Window
Jan 3–4, roughly 2:00–6:00 AM local time
Recommended Gaze
North to northeast sky, away from city lights
Wolf Moon Supermoon
Try to catch the moonrise or moonset to see the 'Moon Illusion' making it appear massive against the horizon. For Jamul observers, this Moon Event will be visible at Palomar Observatory, which offers a reliable escape from the most intense local glare. Coastal mist can be a challenge; choosing a site with even a few hundred feet of elevation is a tactical advantage. Getting away from the urban dome and heading toward Palomar Observatory will make this celestial roadmap truly pop.
Optimal Window
Evening through dawn
Recommended Gaze
Rises in the east, sets in the west
Jupiter at Opposition
This is the best time for high-magnification viewing. Use a 2x Barlow lens if you have one. For Jamul observers, this Planetary Opposition will be visible at Palomar Observatory, which offers a reliable escape from the most intense local glare. The marine layer provides a natural 'heat sink,' resulting in exceptionally steady planetary views for coastal observers. For the best experience, Jamul observers should aim for Palomar Observatory to escape the most intense local glares.
Optimal Window
Sunset through sunrise
Recommended Gaze
East after sunset, south at midnight
Moon & Mars Conjunction
A rare photo opportunity. Use a tripod and a 2-3 second exposure to capture both objects clearly. This is a resilient event; while Orosco Truck Trail's skyglow is present, the target's magnitude will cut through the light. The marine layer provides a natural 'heat sink,' resulting in exceptionally steady planetary views for coastal observers. A drive out of Jamul toward Orosco Truck Trail will significantly improve your chances of spotting the fainter details of this event.
Optimal Window
Shortly after sunset
Recommended Gaze
Southwest sky
Six-Planet Evening Alignment
This parade of worlds is best viewed 45 minutes after sunset before the lower planets set. For Jamul observers, this Planetary Alignment will be visible at Palomar Observatory, which offers a reliable escape from the most intense local glare. Coastal mist can be a challenge; choosing a site with even a few hundred feet of elevation is a tactical advantage. For the best experience, Jamul observers should aim for Palomar Observatory to escape the most intense local glares.
Optimal Window
30–75 minutes after sunset
Recommended Gaze
West to southwest sky along the ecliptic
Total Lunar Eclipse
Watch the colors shift from copper to deep blood-red as the Earth's shadow fully consumes the lunar surface. For Jamul observers, this Eclipse will be visible at Palomar Observatory, which offers a reliable escape from the most intense local glare. Coastal mist can be a challenge; choosing a site with even a few hundred feet of elevation is a tactical advantage. Getting away from the urban dome and heading toward Palomar Observatory will make this celestial roadmap truly pop.
Optimal Window
Late night Mar 2 into early morning Mar 3 (best in western U.S.)
Recommended Gaze
South to southwest sky
Moon, Venus & Pleiades Grouping
This is a great 'naked eye' event, but 10x50 binoculars will reveal the color contrast between the objects. While Jamul has some skyglow, the moderate Class 5 conditions at Palomar Observatory are still excellent for the brightest phases of this event. Colder offshore winds can sharpen celestial focus, though watch for rapid dew accumulation on your tripod. For the best experience, Jamul observers should aim for Palomar Observatory to escape the most intense local glares.
Optimal Window
30–90 minutes after sunset
Recommended Gaze
West-northwest sky
Lyrids Meteor Shower
Look about 45 degrees away from the radiant point for the longest, most dramatic tail streaks. The regional Class 5 baseline at Palomar Observatory is perfectly suited for observing this celestial alignment. Coastal mist can be a challenge; choosing a site with even a few hundred feet of elevation is a tactical advantage. For the best experience, Jamul observers should aim for Palomar Observatory to escape the most intense local glares.
Optimal Window
Late night Apr 21 through dawn Apr 22
Recommended Gaze
Northeast sky
Eta Aquarids Meteor Shower
Patience is key—meteors often come in 'bursts' followed by quiet lulls. For Jamul observers, this Meteor Shower will be visible at Palomar Observatory, which offers a reliable escape from the most intense local glare. Coastal mist can be a challenge; choosing a site with even a few hundred feet of elevation is a tactical advantage. A drive out of Jamul toward Palomar Observatory will significantly improve your chances of spotting the fainter details of this event.
Optimal Window
May 5–6, roughly 3:00–5:30 AM local time
Recommended Gaze
East to southeast sky
Venus & Jupiter Conjunction
A rare photo opportunity. Use a tripod and a 2-3 second exposure to capture both objects clearly. This is a resilient event; while Orosco Truck Trail's skyglow is present, the target's magnitude will cut through the light. Nighttime inversions near the coast often trap steady air, making this a prime window for high-magnification moon study. For the best experience, Jamul observers should aim for Orosco Truck Trail to escape the most intense local glares.
Optimal Window
Just after sunset
Recommended Gaze
West-northwest sky
Mercury, Venus & Jupiter Alignment
Start from the brightest planet and use it as a 'jumping point' to find the fainter ones in the line. While Jamul has some skyglow, the moderate Class 5 conditions at Palomar Observatory are still excellent for the brightest phases of this event. Haze is common in the warmer months; use a light-pollution filter to gain back contrast for these types of events. Getting away from the urban dome and heading toward Palomar Observatory will make this celestial roadmap truly pop.
Optimal Window
20–45 minutes after sunset

Northeast sky
Partial Lunar Eclipse
During totality, the stars nearby will become much more visible as the Moon's glare vanishes. For Jamul observers, this Eclipse will be visible at Palomar Observatory, which offers a reliable escape from the most intense local glare. Summer transparency usually peaks around 2 AM when the day's rising heat has finally radiated away. Getting away from the urban dome and heading toward Palomar Observatory will make this celestial roadmap truly pop.
Optimal Window
Late evening into early morning
Recommended Gaze
South to southwest sky
Saturn at Opposition
Wait for the planet to reach its highest point in the sky to minimize atmospheric 'shimmer'. While Jamul has some skyglow, the moderate Class 5 conditions at Palomar Observatory are still excellent for the brightest phases of this event. The marine layer provides a natural 'heat sink,' resulting in exceptionally steady planetary views for coastal observers. For the best experience, Jamul observers should aim for Palomar Observatory to escape the most intense local glares.

Four-Planet Morning Alignment
This parade of worlds is best viewed 45 minutes after sunset before the lower planets set. The regional Class 5 baseline at Palomar Observatory is perfectly suited for observing this celestial alignment. Coastal mist can be a challenge; choosing a site with even a few hundred feet of elevation is a tactical advantage. For the best experience, Jamul observers should aim for Palomar Observatory to escape the most intense local glares.

Mars & Jupiter Conjunction
A rare photo opportunity. Use a tripod and a 2-3 second exposure to capture both objects clearly. Even with the Class 6 glare near Orosco Truck Trail, the brightest parts of this Conjunction will still be visible to the naked eye. The marine layer provides a natural 'heat sink,' resulting in exceptionally steady planetary views for coastal observers. For the best experience, Jamul observers should aim for Orosco Truck Trail to escape the most intense local glares.
Optimal Window

December Supermoon
Even in a bright city, a Supermoon provides enough contrast for great smartphone photography through an eyepiece. We recommend Jamul residents head to Orosco Truck Trail and look toward the darkest part of the horizon to maximize visibility. Look for the crisp windows between winter storms when the air is scrubbed of all dust and haze.
