Northern Lights Aurora Borealis Seen Over New Jersey
May 11, 2024
ROBBINSVILLE, NJ (MERCER)–Aurora Borealis, also known as the Northern Lights, was seen over New Jersey early this morning after skies cleared last night. Pillars of light in purple, red and green were observed this morning just before dawn.
According to NOAA we are experiencing the aurora because of large Coronal Mass Ejections (CMEs) on the Sun. They are large expulsions of plasma and magnetic field from the Sun’s corona.
If you missed this morning’s aurora you should have another opportunity tonight.
MidJersey.news has had reports of the aurora seen as far south as Florida.

Large sunspots can be seen on the sun this morning causing X-class solar flares and Coronal Mass Ejections (CMEs) creating conditions for the aurora.
According to NASA, Flares happen when the powerful magnetic fields in and around the sun reconnect. They’re usually associated with active regions, often seen as sun spots, where the magnetic fields are strongest. Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest. X-class flare like that can create long lasting radiation storms, which can harm satellites and even give airline passengers, flying near the poles, small radiation doses. X flares also have the potential to create global transmission problems and world-wide blackouts.
YET ANOTHER X-CLASS FLARE!

According to NOAA Space Weather Prediction Center:
Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona. They can eject billions of tons of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar wind interplanetary magnetic field (IMF) strength. CMEs travel outward from the Sun at speeds ranging from slower than 250 kilometers per second (km/s) to as fast as near 3000 km/s. The fastest Earth-directed CMEs can reach our planet in as little as 15-18 hours. Slower CMEs can take several days to arrive. They expand in size as they propagate away from the Sun and larger CMEs can reach a size comprising nearly a quarter of the space between Earth and the Sun by the time it reaches our planet.
The more explosive CMEs generally begin when highly twisted magnetic field structures (flux ropes) contained in the Sun’s lower corona become too stressed and realign into a less tense configuration – a process called magnetic reconnection. This can result in the sudden release of electromagnetic energy in the form of a solar flare; which typically accompanies the explosive acceleration of plasma away from the Sun – the CME. These types of CMEs usually take place from areas of the Sun with localized fields of strong and stressed magnetic flux; such as active regions associated with sunspot groups. CMEs can also occur from locations where relatively cool and denser plasma is trapped and suspended by magnetic flux extending up to the inner corona – filaments and prominences. When these flux ropes reconfigure, the denser filament or prominence can collapse back to the solar surface and be quietly reabsorbed, or a CME may result. CMEs travelling faster than the background solar wind speed can generate a shock wave. These shock waves can accelerate charged particles ahead of them – causing increased radiation storm potential or intensity.
Important CME parameters used in analysis are size, speed, and direction. These properties are inferred from orbital satellites’ coronagraph imagery by SWPC forecasters to determine any Earth-impact likelihood. The NASA Solar and Heliospheric Observatory (SOHO) carries a coronagraph – known as the Large Angle and Spectrometric Coronagraph (LASCO). This instrument has two ranges for optical imaging of the Sun’s corona: C2 (covers distance range of 1.5 to 6 solar radii) and C3 (range of 3 to 32 solar radii). The LASCO instrument is currently the primary means used by forecasters to analyze and categorize CMEs; however another coronagraph is on the NASA STEREO-A spacecraft as an additional source.
Imminent CME arrival is first observed by the Deep Space Climate Observatory (DSCOVR) satellite, located at the L1 orbital area. Sudden increases in density, total interplanetary magnetic field (IMF) strength, and solar wind speed at the DSCOVR spacecraft indicate arrival of the CME-associated interplanetary shock ahead of the magnetic cloud. This can often provide 15 to 60 minutes advanced warning of shock arrival at Earth – and any possible sudden impulse or sudden storm commencement; as registered by Earth-based magnetometers.
Important aspects of an arriving CME and its likelihood for causing more intense geomagnetic storming include the strength and direction of the IMF beginning with shock arrival, followed by arrival and passage of the plasma cloud and frozen-in-flux magnetic field. More intense levels of geomagnetic storming are favored when the CME enhanced IMF becomes more pronounced and prolonged in a south-directed orientation. Some CMEs show predominantly one direction of the magnetic field during its passage, while most exhibit changing field directions as the CME passes over Earth. Generally, CMEs that impact Earth’s magnetosphere will at some point have an IMF orientation that favors generation of geomagnetic storming. Geomagnetic storms are classified using a five-level NOAA Space Weather Scale. SWPC forecasters discuss analysis and geomagnetic storm potential of CMEs in the forecast discussion and predict levels of geomagnetic storming in the 3-day forecast.

Blacksmith Triangle, the site of a former gas station at the corner of North Olden and Lawrence avenues in Trenton, has taken on a new life as the city’s latest green space.
New Jersey Conservation Foundation (NJ Conservation), in partnership with the City of Trenton and other environmental and community organizations, worked to transform the site into a forested park addition over the last two years. Improvements included site clearing and grading, seeding, new sidewalks, bollards, a brick-paved entry plaza, and 14 honey locust trees. The project’s completion was celebrated in May.
The City remediated Blacksmith Triangle years ago to clean up the contamination left behind from its former use as a gas station. But until recently it remained covered with concrete and asphalt and was often used as a de facto parking lot. In 2024, NJ Conservation received a grant from the Licensed Site Remediation Professionals Association Foundation to plant trees on the site, which spurred conversations with Trenton officials about turning the lot into a forested plaza and gateway to George Page Park and the Assunpink Greenway. Construction began in December 2025, thanks to a significant financial contribution from the City of Trenton and additional funding secured by NJ Conservation from private donors.
With this new green space, project leaders aim to increase shade for city residents, who are experiencing disproportionate impacts of climate change. Trenton neighborhoods are dealing with the ‘heat island effect’ that causes higher ambient temperatures in urban areas than in suburban and rural areas.
“Excessive heat is deadly in our communities, and this work will help future generations of Trentonians cope with the rising temperatures that will come with our new climate realities,” said Jay Watson, NJ Conservation’s Senior Fellow for Conservation Justice. “New Jersey Conservation Foundation is proud to do this green infrastructure work in our capital city.”
At a grand opening celebration for Blacksmith Triangle last month, Paul Harris, Trenton’s Director of Recreation, Natural Resources, and Culture, said the City is excited about the lot’s transformation, highlighting the partnership that made the project possible.
“Our goal is to green as much of the town as we can, but in order to do that successfully, we need to bring on partners,” said Harris.
The revitalization of Blacksmith Triangle is part of a larger greening effort throughout the city. NJ Conservation and its partners — City of Trenton, Isles, the New Jersey Tree Foundation, the Watershed Institute, and the Outdoor Equity Alliance — are working to build a greener, more equitable New Jersey through the Trees for Trenton program. Thanks to a grant from the New Jersey Department of Environmental Protection, 1,000 shade trees are being planted throughout Trenton, creating a healthier environment for residents and visitors.
Trees for Trenton was announced in 2023 at an Arbor Day celebration when the first trees were planted at Mulberry Street Park. More than 900 trees have been planted throughout the city since then.
