Dawn and dusk12/9/2022 These times are considered to be the best for photographers, with very little artificial light. Blue hour is a shorter time period between -4° and -6°. Golden hour refers to when the Sun is just dipping below the horizon, between 6° and -4°. You also may hear the terms golden hour and blue hour. So whilst all of these three periods of time are considered twilight, we still separate them from each other. This is astronomical twilight, and it’s when we can see the majority of stars and objects in our night sky clearly. You can still make out the silhouettes of trees on the horizon, but it’s too dark to see them properly.įor astronomers, we’re waiting for the time that the Sun is between 12° and 18° beneath the horizon. This is when the Sun is between 6° and 12° beneath the horizon. Things are still clearly visible around us, however it’s around the time you turn your garden lights on, and the street lights come on the side of the street.Īfter civil twilight comes nautical twilight, named because it was used as a navigational tool by seafarers who used the stars to help them navigate the seas. This is when the Sun is between 0° and 6° below the horizon. In the evening, first comes civil twilight. Twilight is separated into three different periods, depending on how far the Sun is beneath the horizon. So, let’s look at the stages of both and see how they’re different. This is a very simple explanation when nautical, astronomical and civil twilight occurs, and it’s the perfect time for astronomical observations. So, twilight directly transcends into dusk when the Sun is 18° beneath the horizon. Dusk is the period after twilight, when the sky is dark and the stars are easily visible. Twilight simply refers to the period of time after the sun sets beneath the horizon, and the sky begins to get darker for us. But how do you differentiate them from each other? Well, that’s what we’ll be defining the difference between twilight and dusk. Whilst they’re around the same period of time as each other, we generally refer to them as different periods of time when the Sun is falling below our horizon.Īnd when the Sun begins to drop beneath the horizon, these different twilight types begin to become noticeable. Animals such as possums, raccoons, and squirrels may not seem threatening, however, swerving to avoid hitting something in the road could have disastrous consequences.Many people get confused between the difference between twilight and dusk. Apply this same caution to driving in the city around dawn and dusk. If you have driven in rural areas, you’re probably used to watching roadsides for wildlife. Keep your eyes peeled as you drive through residential areas for anyone on foot or on a bicycle and slow down if you spot someone. Since the sky is still light, pedestrians may believe you can see them. Pedestrians and bikers are difficult to spot during these hours. #DAWN AND DUSK DRIVERS#Be aware that other drivers may be drowsy as well – so watch for vehicles that have trouble maintaining their speed or are swerving between lanes. If you find yourself distracted or having issues focusing on the road, pull over. Because the sun rises late and sets early this time of year, it’s likely you’ll be out driving during these times. Our brain is hard-wired to be sleepy when it’s dark outside. Be sure to do this only when you are parked or your car is not in motion, so that you are not distracted from driving. Make sure you’re still able to read the gauges when dimming the dash. Turning down your dash lights will help prevent the problem. Looking between the bright dash lights and the darkening road can make it difficult for your eyes to adjust in time to spot any issues. Use the switch to ensure your headlights are on and stay on throughout the drive. While many newer cars have daytime running lights and automatic headlight options, don’t take those for granted. In order to stay safe during these hazardous driving times, follow these tips: Turn on your headlights.Īlthough you may not need them to see where you’re driving, your headlights should be switched on to make your vehicle easy to see. The sun is often low enough in the sky to cause glare in drivers’ eyes, while deep shadows can make it difficult to spot changing road conditions. Both dawn and dusk are some of the most dangerous times to drive.
