There’s no denying that the occultation or close pass (depending on your location) event with the Moon and Jupiter on 17 May will be hard to observe, as it takes place during daylight hours.
However, given clear skies, Jupiter can definitely be seen in a blue sky, either using binoculars or through a telescope.
A good challenge is to go one further and try to photograph the planet.
In this guide we’ll show you how you can capture the close pass or – if you’re in the right location – the lunar occultation of Jupiter on 17 May.
A daylight sky will greatly reduce contrast in the visible spectrum, but as long as you can locate Jupiter, switching to an infrared pass filter combined with an infrared-sensitive camera should make it possible to improve the view.
If you don’t have such equipment, don’t worry.
It’s still possible to get an unfiltered shot of the planet using a DSLR, but you may need to work a bit harder to separate its dim, low-contrast disc from the sky.
Find out more in our guide to DSLR astrophotography.
The event on 17 May will have the benefit of the Moon being nearby, but even this may be challenging.
With a waning crescent phase at 7% illumination, the Moon too will appear quite indistinct against the blue sky.
There are various ways to locate the Moon during daytime. The easiest is to catch it earlier as it rises in darker skies.
On 17 May 2023 this will happen around 04:30 BST (03:30 UT) from the centre of the UK.
Using a polar-aligned equatorial telescope mount, you’ll need to set the drive to its lunar rate, then centre the view on the Moon’s disc.
If you’re unsure about the precision of the polar alignment, you’ll need to schedule in periodic checks.
Another method is to estimate where the Moon will be at a set time and try to locate it that way.
At 11:24 BST (10:24 UT), the Moon will appear at an altitude around 47° due south.
This should give you enough information to get into the general area.
As ever, take great care when looking as the Sun will be up and relatively close by.
Observing from safely inside the shadow of a building so the Sun can’t be seen is a good strategy to keep safe.
Viewing the Sun with the naked eye is extremely dangerous, so care must be taken at all times.
Once you have managed to locate the Moon, Jupiter should be a lot easier to find.
Just be prepared for its disc to be extremely low in contrast, almost a ghost of its nighttime self.
Use the Moon as your focus target, taking care to focus as accurately as possible.
The sky can be bright, but don’t allow it to over-expose or you won’t be able to recover the planet.
Once taken, adjust the levels of the image using your favourite image-editing program (have a look at our list of the best free astronomy software), darkening the sky with the mid-point slider and tweaking to bring out weak Jupiter at its best.
Watching the celestial event safely is possible with the right equipment and some preparation.
With the upcoming total solar eclipse on April 8, 2024, the New England College of Optometry (NECO) urges the general public to observe this celestial phenomenon safely. Solar eclipses are rare events that spark widespread interest and excitement. To ensure everyone can enjoy the eclipse without risking their vision, NECO is sharing crucial guidelines for proper viewing.
“Solar eclipses present a wonderful opportunity for communities to engage with astronomy, but it’s vital that safety is a priority,” says George Asimellis, PhD, Msc, MBA, Professor of Vision Science at NECO. “Viewing a solar eclipse without appropriate protection can result in solar retinopathy, which can cause lasting damage to the eyes. You must take proper precautions to view the eclipse.” PLEASE NOTE: NECO recommends that individuals who have recently undergone eye surgery or who have chronic eye conditions should refrain from viewing the eclipse.
NECO will host an eclipse viewing party on Monday, April 8, from 2:00-4:00pm at their main campus located at 424 Beacon Street in Boston’s Back Bay. Media are welcome to attend and receive a free pair of eclipse viewing glasses. Faculty will be present to talk about the science behind safely viewing an eclipse.
The map below (courtesy of NASA) shows the eclipse’s path of totality.
For those who reside outside the path of totality: The Boston area is outside the eclipse’s path of totality. However, we will be able to view a partial eclipse starting at about 2:10pm. Our area will experience moderate darkness and a drop in temperature during the partial eclipse, which will last two hours. Eclipse glasses must still be used to protect your eyes from the harmful rays of the sun, even during a partial eclipse!
Our vision experts are available for comment and additional information on eye care during this astronomical event. Please contact our Marketing Department by calling (617) 587-5609, or email [email protected].

One of the largest studies on wildlife activity—involving more than 220 researchers, 163 mammal species and 5,000 camera traps worldwide—reveals that wild animals react differently to humans depending on where the animals live and what they eat.
Bigger herbivores—plant-eating animals like deer or moose—tend to become more active when humans are around, while meat-eaters like wolves or wolverines tend to be less active, preferring to avoid risky encounters.
Urban animals like deer or raccoons may become more active around people, as they get used to human presence and find food like garbage or plants, which they can access at night. But animals living farther from cities and other developed areas are more wary of encountering people.
The new study, a collaboration across researchers from 161 institutions, used data from before and during the COVID-19 lockdowns to examine wildlife behaviour amid changing human activity levels.
“COVID-19 mobility restrictions gave researchers a truly unique opportunity to study how animals responded when the number of people sharing their landscape changed drastically over a relatively short period,” said lead author Dr. Cole Burton, an associate professor of forest resources management at UBC and Canada Research Chair in Terrestrial Mammal Conservation.
“And contrary to the popular narratives that emerged around that time, we did not see an overall pattern of ‘wildlife running free’ while humans sheltered in place. Rather, we saw great variation in activity patterns of people and wildlife, with the most striking trends being that animal responses depended on landscape conditions and their position in the food chain.”
In Canada, researchers monitoring areas such as Banff and Pacific Rim national parks, Cathedral, Golden Ears and South Chilcotin Mountains provincial parks, and the Sea-to-Sky corridor in B.C. found that carnivores like wolverines, wolves and cougars were generally less active when human activity was higher.
In several of these parks, and in cities such as Edmonton, large herbivores often increased their activity but became more nocturnal with the presence of more humans. Large carnivores were notably absent from the most human-dominated landscapes.
These findings highlight the importance of measures to minimize any detrimental effects of human disturbance on wildlife, including reducing overlaps that might lead to conflict.
“In remote areas with limited human infrastructure, the effects of our actual presence on wildlife may be particularly strong. To give wild animals the space they need, we may consider setting aside protected areas or movement corridors free of human activity, or consider seasonal restrictions, like temporary closures of campsites or hiking trails during migratory or breeding seasons,” said study co-author and UBC biologist Dr. Kaitlyn Gaynor.
She added that strategies must also fit specific species and locations. In more remote areas, keeping human activity low will be necessary to protect sensitive species. In areas where people and animals overlap more, such as cities, nighttime is an important refuge for wildlife, and keeping it that way can help species survive. Efforts may focus on reducing human-wildlife conflict after dark, such as more secure storage of trash bins to reduce the number of animals getting into human food sources, or use of road mitigation measures to reduce vehicle collisions.
The findings are particularly useful amid the surge in global travel and outdoor recreation post-pandemic, Dr. Burton added.
“Understanding how wildlife respond to human activity in various contexts helps us develop effective conservation plans that have local and global impact. For that reason, we are working to improve wildlife monitoring systems using tools like the camera traps that made it possible to observe animal behaviours during the pandemic.”
