Impact! BRAMON record lunar impact during the Eclipse of the Moon

A BRAMON camera recorded a lunar impact during the January 21 eclipse of the Moon. The impact was recorded in João Pessoa, Brazil and also by several other cameras around the world.

To cover the eclipse in João Pessoa, the Association of Astronomy of Paraiba and the Cabo Branco Station (organ linked to the city hall), promoted a public event in the gardens of the Station. Marcelo Zurita, who is a member of the Association and also of BRAMON, prepared a telescope with two cameras, one to transmit the eclipse in real time to a screen and another to monitor lunar impacts at the moment of totality. The videos of the two cameras were being recorded, and in last Monday night when watching one of the videos, he perceived a flash occurred in first moments of the beginning of the totality.

After reporting the flash to his colleagues at BRAMON, there were reports from other people around the world who had noticed the flash in a transmission from the timeanddate portal (https://imgur.com/VSpNGVi).

Already this Tuesday morning, we received the official confirmation: the MIDAS project, which has observatories in Spain dedicated to the observation of lunar impacts, registered the same flash at 04:41:38 UT.

This is the first time a lunar impact is recorded during a total eclipse around the world. Earlier, there was a record of a possible 2008 impact, which was unconfirmed because it was recorded by only one camera. But this last is certainly the most recorded impact in history. Several cameras broadcasting the live eclipse also recorded a phenomenon.

In Brazil this will be only the second lunar Impact recorded in video in history. The first was in December 2017 during the Geminid meteor shower.

UPDATE 1: New Brazilian video of impact in Cascavel, PR
In a video published on Youtube on January 22, Edinei Oliveira from Cascavel, Brazil, informs that he has also recorded the impact during the eclipse. We checked the video and it looks legitimate, with the impact flash appearing exactly in the same position as it was recorded by BRAMON and by several cameras around the planet. Look the video below:

UPDATE 2: Another Brazilian video of the impact recorded in Campina Grande, PB
Diego Rhamon, a Meteorology student from Campina Grande, in Paraíba, released the third Brazilian video of this impact. Diego, who is also a member of BRAMON, has the habit of videotaping meteorological and astronomical phenomena. Then, we asked him to check if he had recorded something on the eclipse night, at 1:41 (local time) and when he checked, he had discovered that recorded the impact flash. Check out the video:
