Weakening of Earth's magnetic field probed

Geophysicists have been puzzling over a gradual weakening of the Earth's magnetic field in an area stretching from Africa to South America, which has resulted in technical disturbances in satellites orbiting Earth.

Scientists have resorted to data from the European Space Agency's (ESA) Swarm constellation to probe the disturbing weakening of Earth's magnetic field in the area known as the "South Atlantic Anomaly".

Jurgen Matzka, from the German Research Centre for Geosciences, and a team of experts from the Swarm Data, Innovation and Science Cluster (DISC) have been using data from ESA's Swarm satellite constellation to identify and measure the different magnetic signals that comprise Earth's magnetic field.
"The new, eastern minimum of the South Atlantic Anomaly has appeared over the last decade and in recent years is developing vigorously. We are very lucky to have the Swarm satellites in orbit to investigate the development of the South Atlantic Anomaly. The challenge now is to understand the processes in Earth's core driving these changes," said Matzka.

Moon halo seen in Canberra
Australians observed a mysterious halo around the moon on Wednesday night.

People living in New South Wales and the Australian Capital Territory observed differently sized rings around the moon, which appeared to change depending on where people viewing them lived.

Canberrans reported seeing a ring around the moon while others in the NSW towns of Moss Vale, Callala Bay, Woonona, Camberwarra and Culburra also saw it.

Many people posted pictures of the night sky phenomenon to social media, questioning what exactly had caused the ring to appear.

On April 14, 2020, YouTube user 'Merz' recorded strange sounds he heard in the sky over Drogheda, Ireland:

The above clip is his second video of strange sounds. He recorded another event back in March of 2016. He states that the sounds have been heard since that time, but not as hectic:

Strange 'metallic' noise heard in Albacete, Spain

On April 22, 2020, YouTuber 'Noel James Riggs' awoke to hear a strange "metallic sounding noise" outside his home in Albacete, Spain. He thought the sounds might have come from construction nearby, but realized it was early Saturday morning and decided to investigate:
Strange "metallic" sounding noise recorded between 6:30 - 7:00 AM on a Saturday morning in Albacete, Spain. The noise was very loud and there was no construction or large machines in the area at the time and this area is not near a factory or train station. These strange sounds can be heard in places all over the world. Sometimes they are called "Sky trumpets" etc. Nobody knows the source of this sound and as far as I know there is no scientific research going on to try and find the source. I had recorded a much longer audio recording with a HQ digital recorder when I decided to go back inside to record a video. This video recording is at the tail end of the phenomenon.


'Loud flute sounds' heard coming from the sky in Lakeland, Florida

On April 23, 2020, YouTube user 'Iron Rails And Pipe Dreams' recorded strange 'flute' sounds he heard around 8 a.m. that morning outside his home:
I began hearing these sounds at around 8:40am from inside my house this morning and they only kept intensifying as the morning dragged on. Finally unable to sleep, I grabbed my phone and began recording them. Interesting! The only place I've ever heard these sounds are here on YouTube from various videos people uploaded.


Strange sounds heard in the sky above Domodedovo, Russia

Strange sounds were recorded by a resident of Domodedovo, Russia. The noise resembled a siren or the voice of a horror movie. Someone heard the wind in the strange sound... a warning about impending cataclysms.
According to the author of the video, the strange noise started around 03:00 a.m. and lasted until approximately 03.40 a.m. The author of the video told MK reporters:
The window was ajar. I already went to bed and heard these sounds. At first it seemed to me that this was howling dogs or something. I opened the window to the fullest, and the sound became clearer and very strange in nature. I have never heard anything like it before. All this lasted about 15 minutes.

According to users of social networks, a similar anomalous noise has already been recorded in different corners of the planet, and it itself may be a harbinger of cataclysms or even an apocalypse.

Director of the Institute for Earthquake Prediction Theory and Mathematical Geophysics of the Russian Academy of Sciences Peter Shebalin blames the planes for everything. According to him, the source of noise could be two flying aircraft, which created sound resonance.

Strange 'trumpet' sounds disturb the night in Buenos Aires, Argentina

Last night, social networks exploded after hundreds of residents claimed to have heard strange sounds "like sirens" or "trumpets" in the sky of cities in the western suburbs. What does buzz have to do with coronavirus quarantine?

For several nights now, citizens have been claiming to hear different quasi-apocalyptic sounds from the skies of different cities around the world. Argentina is no stranger to this phenomenon that occurs mainly in countries that go through quarantines in the middle of the coronavirus pandemic.

The explanations are not very reliable. From supposed "sky-bikes", a kind of collision of hot and cold air masses to radio frequencies that propagate in the ether.


What's up will all these booms, Mason City, Iowa?

A frost explosion. A meteor sonic boom. Blown transformer. Trains. Tannerite. Fireworks. Build ups in the sewer line. Aliens.

Yes. Aliens.

All these have been offered up as possible culprits for a semi-regular, unexplained "boom" that's been heard by residents of Mason City for the past few years.

Map shows the most recent locations of booms heard and reported on local social media platforms.

Some insist they only hear it in the southeast part of town, while others insist it's farther north.

Even the intensity of the boom isn't wholly agreed upon. Some of that could be explained by location. The farther away you are from something, the less intense it's going to sound, after all.


Strange trumpeting sounds heard in Anchorage, Alaska

On November 25, 2019, YouTuber 'Shannon Maybe' shared footage of strange trumpet sounds she heard in the skies of Anchorage, Alaska around 1:00 a.m.

A commenter on the video attributed the sound to road graters which she dismissed:
... it's not tho.. I looked up other videos on here and the sounds are the same in other states, some during the days and with no snow out...
Another commenter said the noise was from the HAARP project, to which she replied:
I've lived here my whole life, I've never heard that here before ever! HAARP is here in Alaska.


'Boom!' Sonoma Valley, California residents look to skies for answer following nocturnal noises

An amateur astronomer sets up his home-made 18" Newton Reflector during the monthly public viewing night at the Ferguson Observatory in Sugarloaf Park. Though there were few reported meteors on the night of Nov. 21, many people heard distant sonic booms with no known source.
People all over Sonoma County looked up at about 7:40 p.m. on Thursday, Nov. 21, when a brief series of "booms" rolled across the valleys. But there was no glow in the sky, the stars were visible in the cloudless sky. Was it thunder?

Or was it a meteor?

It may be no coincidence that the sound corresponded to a large but infrequent meteor shower, known as the Unicorn (or Monocerotids, from the constellation of its visible origin), seen only every 25 years or so - and last reported in 1995. But meteors are usually silent apparitions, fleeting and ghostly.

In social media groups, many people dialoged about the Thursday night noises. Descriptions of the noises ranged from "rumbles like thunder" to "like a limb fell on the house."

And it didn't seem to be particularly localized, but strong throughout the Sonoma Valley, in Nextdoor neighborhoods from Temelec to Denmark Street. Similar social media networks reported the noises at about the same time in Healdsburg, 25 miles away. Others on Facebook said it was heard in Sebastopol, Santa Rosa, Cloverdale, Petaluma, Napa and Marin.
