One of the most breathtaking and surreal scenes was caught on camera in Jogjakarta, Indonesia as its night sky lights up when a meteor suddenly enters the atmosphere and crashes into the Mount Merapi volcano there. Making its rounds in social media, a video of the majestic meteor was shared by @jogjaupdate yesterday.

The footage itself was actually from Thursday (27 May 2021) and was captured by a CCTV from Megadata, an internet service provider company in Indonesia. Specifically, the CCTV footage was recorded from a Megadata facility in Kalitengah Kidul, Jogjakarta which is where Mount Merapi is located.

New Comet C/2021 K1 (ATLAS)

CBET 4968 & MPEC 2021-K89, issued on 2021, May 27, announce the discovery of a new comet (magnitude ~17.0) on CCD images taken on May 14.5 UT with the 0.5-m reflector + CCD in the course of the ATLAS-HKO (T05) survey. The object was originally found by Peter Veres of Minor Planet Center (MPC) as unusually bright among the MPC's isolated tracklet file (ITF) and linked to the detections from May 22 (F51) and May 14 (T08). A review of the ATLAS images revealed the cometary nature of this object.

As with the ATLAS observations, this object was reported without comments by Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala on May 22.6 UT (mag 17.6-18.0), submitted as two separate objects on the same night. This object has been found to show cometary appearance also by CCD astrometrists elsewhere after it was posted on the MPC's PCCP webpage. The new comet has been designated C/2021 K1 (ATLAS).

Stacking of 44 unfiltered exposures, 60 seconds each, obtained remotely on 2021, May 27.3 from X02 (Telescope Live, Chile) through a 0.61-m f/6.5 astrograph + CCD, shows that this object is a comet with a compact coma about 20" arcsecond in diameter and a tail 30" long in PA 245 (Observers E.

Loud boom, shaking in Virginia Beach, Virginia

If you heard a loud boom at the Oceanfront and other areas in Hampton Roads, you're not alone.

Several people are reporting their house shook and there were booming sounds this morning, with the first around 11 a.m.

One person in north Virginia Beach said they heard "a loud noise like thunder" in First Landing Park off of Shore Drive. In Hampton and Poquoson, several residents said their windows rattled and they felt their houses shake.

Paul Carusol, a seismologist with United State Geological Services, said the agency saw a spike on its seismometers.

Don Blakeman, another seismologist with the agency, said analysts with USGS do not believe there was an earthquake.

When asked whether jets could cause some kind of sonic boom and show up on the agency's monitors, Blakeman said it's possible. Over the years people from Virginia and the Carolinas have called USGS thinking there was an earthquake, which Blakeman said turned out to be a sonic boom caused by military activity.

Shortly before 10 PM on Tuesday May 25 2021, a large fireball streaked across the sky of the Mid Atlantic US. This was centered over Maryland and captured by various cameras. Thanks to Mike Hankey, his All Sky Cam network, and the American Meteor Society for enhancing the documentation of the event.

A beautiful meteor was seen on the night of Saturday, May 22, in four states in the Northeast. The phenomenon occurred at 18:59 (Brasília time) on the coast of Rio Grande do Norte and was recorded by the cameras of BRAMON and Clima ao Vivo in Rio Grande do Norte, Paraíba, Pernambuco and Ceará.

Comets cause meteor showers on Earth

The meteoroid stream of long-period comet Thatcher from CAMS data. Outer blue ellipse is the orbit of Neptune.
Comets that circle the Sun in very elongated orbits spread their debris so thin along their orbit or eject it out of the solar system altogether that their meteor showers are hard to detect. From a new meteor shower survey published in the journal Icarus, researchers now report that they can detect showers from the debris in the path of comets that pass close to Earth orbit and are known to return as infrequent as once every 4,000 years.

"This creates a situational awareness for potentially hazardous comets that were last near-Earth orbit as far back as 2,000 BC," said meteor astronomer and lead author Peter Jenniskens of the SETI Institute.

Jenniskens is the lead of the Cameras for Allsky Meteor Surveillance (CAMS) project, which observes and triangulates the visible meteors in the night sky using low- light video security cameras to measure their trajectory and orbit. There are CAMS networks now in nine countries, led by co-authors on the paper.

In recent years, new networks in Australia, Chile and Namibia significantly increased the number of triangulated meteors. The addition of these networks resulted in a better and more complete picture of the meteor showers in the night sky.

"Until recently, we only knew five long-period comets to be parent bodies to one of our meteor showers," said Jenniskens, "but now we identified nine more, and perhaps as many as 15."

The American Meteor Society (AMS) received 5 reports (event 2847-2021) about a meteor fireball seen over Casablanca-Settat, Drâa-Tafilalet, Marrakesh-Safi and Souss Massa on Monday, May 17th 2021 around 20:31 UT.

For this event, the AMS received 2 videos.

New meteor impact crater discovered on Mars

meteor crater mars
Meteors hit much harder on Mars than they do on the Earth. Lack of atmosphere obviously contributes to that, but its proximity to the asteroid belt also makes the red planet a more likely target for some gravitationally disturbed rock to run into. Now that we have a satellite infrastructure consistently monitoring Mars, we are able to capture the aftermath of what happens when it is pummeled by space debris, and the results can be dramatic.


One powerful tool in that impact hunting toolkit is the Mars Reconnaissance Orbiter (MRO). It has a variety of instruments on it that make it possible to both track down areas of interest and then follow up with high resolution imagery, incluidng HiRISE, the camera that took the picture above. That is exactly what happened with a new crater that the satellite noticed on one of its flybys.

Comment: Considering the above, it's notable that there's been a significant uptick of fireballs and NEOs recorded on Earth in recent years: Also check out SOTT radio's:
