Meteor seen across Puerto Rico at approximately 8:02 PM Friday 7th May 2021
A bright meteor was spotted across the night skies of the Greater Antilles on Friday night. Those who spotted it say the brilliant meteor appeared as a "huge green ball with a long tail."

The meteor was visible from Puerto Rico, the Dominican Republic and Cuba at approximately 8:02 PM Friday 7th May 2021.

According to the Caribbean Astronomy Society (SAC), "It was a space rock of metallic content friction with our atmosphere."

New Comet C/2021 E3 (ZTF)

CBET xxxx & MPEC 2021-J71 , issued on 2021, May 06, announce the discovery of an apparently asteroidal object (magnitude ~19.5) on CCD images taken on March 09.5 UT with the 1.2-m Schmidt telescope at Palomar in the course of the "Zwicky Transient Facility" (ZTF) search program. This object has been found to show cometary appearance by CCD astrometrists elsewhere. The new comet has been designated C/2021 E3 (ZTF).

Stacking of 14 unfiltered exposures, 120 seconds each, obtained remotely on 2021, March 19.2 from Z08 (Telescope Live, Oria) through a 0.7 m f/8 Ritchey Chretien + CCD, shows that this object is a comet with a compact coma about 7" in diameter (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).

A huge, glowing fireball lights up the sky over Japan

A glowing object crossing the sky was captured on Monday night over the Fukuoka and Nagasaki prefectures in Japan. The phenomenon was captured on video by cameras in the area and seen by several witnesses who described it as a ball of light, pick up the chain NHK.

Satoshi Imamura, an expert in space issues, dispelled doubts about the nature of the object and explained that it was a bright shooting star known as a fireball or bolide. The intense luminosity occurs when dust and asteroid fragments in outer space enter the atmosphere and burn.


Meteor fireball spotted on deputy's dashcam in Collier County, Florida

A Collier County deputy captured a unique phenomenon on her dashcam while out on patrol this week.

Cpl. Nicole Medenwald saw a meteor, and rather than savor the memory, she got to review the proof!

The Collier County Sheriff's Office said she had just come from conducting a traffic stop. She repositioned her patrol car to face North 15th Street to watch for cars.

"I saw a green light and then it lit up the sky," Cpl. Medenwald said. "It reminded me of lightning at night the way the sky lit up."

Cpl. Medenwald said she's seen meteors before but has never seen one break the atmosphere and light up the sky.


Flaming meteor fireball seen in Oman's sky

The Sultanate on Wednesday evening saw the emergence of a flaming fireball in the sky over some regions.

Speaking exclusively to the Times of Oman, Yusuf bin Zahir Al Salmi, Official of Al Huwqain Astronomical Observatory, said: "Eyewitnesses from Al Huwqain, Wadi Bani Ghafir villages in the Wilayat of Rustaq in South Al Batinah Governorate and from the Wilayats of Ibri, Yanqul, and Dhank in Al Dhahirah Governorate, reported that at exactly 8:28 pm on Wednesday's evening the 15th of Ramadan, April 28, 2021, a very bright white light was seen tending to blue, penetrating clouds, starting from the northeast, heading to the southwest, and after a few seconds an explosion followed."

Lyrid fireball over the Mediterranean (April 23)

This bright Lyrid meteor was recorded over Spain on 2021 April 23 at 6:03 local time (equivalent to 4:03 universal time). It overflew the Mediterranean Sea. The bolide was generated by a fragment (a meteoroid) from Comet C/1861 G1 (Comet Thatcher) that hit the atmosphere at about 165,000 km/h. It began at an altitude of about 114 km over the Mediterranean Sea, and ended at a height of around 60 km, after traveling about 53 km in the Earth's atmosphere.

The event was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN), from the meteor-observing stations located at La Hita (Toledo), Calar Alto (Almería), Sierra Nevada (Granada), La Sagra (Granada), and Sevilla.


NASA to participate in tabletop exercise simulating asteroid impact

This image was captured by the International Space Station Expedition 59 crew as they orbited 400 kilometers above Quebec, Canada. Right of center, the ring-shaped lake is a modern reservoir within the eroded remnant of an ancient 100 kilometer diameter impact crater, which is over 200 million years old.
JPL's Center for Near Earth Object Studies will lead the hypothetical impact scenario to see how international agencies respond to an actual impact prediction.

During the week of April 26, members of NASA's Planetary Defense Coordination Office (PDCO) will participate in a "tabletop exercise" to simulate an asteroid impact scenario. The exercise depicting this fictional event is being led by NASA's Jet Propulsion Laboratory's Center for Near Earth Object Studies (CNEOS), allowing NASA's PDCO and other U.S. agencies and space science institutions, along with international space agencies and partners, to use the fictitious scenario to investigate how near-Earth object (NEO) observers, space agency officials, emergency managers, decision makers, and citizens might respond and work together to an actual impact prediction and simulate the evolving information that becomes available in the event an asteroid impact threat is discovered.

The fictitious impact scenario will occur during the 7th IAA Planetary Defense Conference, hosted by the United Nations Office for Outer Space Affairs in cooperation with ESA (European Space Agency), and will evolve over the five days of the conference, starting Monday, April 26. At several points in the conference program, leaders of the exercise will brief participants on the latest status of the fictitious scenario and solicit feedback for next steps based on the simulated data that is "discovered" each day. These type of exercises are specifically identified as part of the National Near-Earth Object Preparedness Strategy and Action Plan developed over a three-year period and published by the White House in June 2018.

Comment: Meanwhile a record number of asteroids were observed flying past Earth in 2020 - Despite lockdowns interrupting surveys.

Dozens report bright meteor fireball in New Hampshire skies

Fireball over Manchester, NH
Dozens of people in New Hampshire, Maine and Massachusetts reported seeing a bright fireball streak across the sky Sunday night.

The American Meteor Society received at least 45 reports of the meteor from as far away as Nova Scotia, Rhode Island and Vermont. Based on the reports, it's likely the fireball entered the atmosphere above the ocean off the coast of Maine at about 8:20 p.m. and streaked northwest above Casco Bay.

A surveillance video captured by a Nest security camera in Rochester submitted by a local user shows a short, bright streak of light in the sky. The submitter said the fireball was accompanied by a loud boom, and an emailer from Strafford told News 9 his house shook after the fireball was seen. Just one of the reports submitted to the AMS indicated that the witnesses hadn't heard any sound.
