The effect was reported by Brazilian amateur astronomer Jose Luis Pereira and verified a day later by Harald Paleske from Langendorf, Germany. At the time, Paleske had been taking a video of the transit of Ios shadow when the event occurred, which looked like a two-second flash. Upon evaluating the video footage, he eliminated the possibility that the event happened closer to Earth (with Jupiter merely being the background).

After an extensive examination, Paleske figured out that the effect happened at Jovian latitude 106.9 ° (CM1), longitude +3.8 °, and timed it to 22:39:27 UTC on Sept. 13th. The effect was individually observed by two groups of French amateur astronomers with the SLA. According to a declaration released by the SLA, the 2 groups consisted of:
” Jean-Paul Arnould from his observatory in Villey-le-sec with the C11 telescope of the SLA [and] a group made up of Thibaut Humbert, Stéphane Barré, Alexis Desmougin, and Didier Walliang at the Astroqueyras observatory in Saint-Véran, with the 62 cm diameter telescope Other individuals worldwide have observed the same phenomenon. This is the very first time that many individuals (currently 9) have actually caught this type of occasion.”
Thanks to the DeTeCt software/project, the expert and amateur huge neighborhood was issued a large alert that enabled for rapid responses. All throughout the world, instruments that were focused on Jupiter were spoken with to see if they also tape-recorded the light flash on the Jovian gas giant. The SLA also sent out the information to Marc Delcroix, a Senior Research Scientist at the NTT Communication Science Laboratories Media Information Laboratory in Kyoto, Japan.
Based on the images and video supplied observers, the objects diameter is estimated at 20 meters (ft). Similar to what occurred with SL-9, this things is believed to be the residue of a larger comet or asteroid that was caught by Jupiters gravity that broke up quickly before the impact happened. This info and any updates on the occasion can be discovered at Delcroixs site, who indicated that this impact might be the brightest ever observed by amateur astronomers (save for the SL-9 effect).
” Aside Comet Shoemaker-Levy 9 effects in 1994, never ever an effect was so well covered!” he wrote. Over the coming days and weeks, Delcroix and the astronomical neighborhood will examine the amateur videos to find out more about the lightcurves the impact created. From this, they want to get information on the quantity of energy launched, the characteristics of the effect, the physical characteristics of the impactor itself.
” Many thanks to every amateur who was implied in this occasion, whether finding it, observing it, searching for it in his capture without finding it, or spreading out the alert (there were hundreds of shares). Special thanks to the amateurs of the French astrosurf forums who assisted me a lot to learn information on discoveries or brand-new observations. We beginners demonstrated our force as a neighborhood, revealed our inspiration, devotion and experience through this fantastic event!”
Whereas effects with Jupiter were as soon as thought to be unusual, they are now understood to be a regular occurrence. With modern opportunities for data-sharing, networking, and partnership in between specialists and novices, occasions that would have otherwise gone unnoticed are being spotted with regular frequency.

In 1994, the Comet Shoemaker-Levy 9 (SL9) affected Jupiter, which had actually recorded the comet shortly before (and broken apart by its gravity). The event became a media circus as it was the very first direct observation of an extraterrestrial collision of Solar System items. The impact was so powerful that it left scars that withstood for months and were more discernible than Jupiters Great Red Spot.
Ever since, astronomers have observed multiple objects impacting Jupiter, and it is anticipated that such effects take place all the time (though unnoticed). On September 13th, 2021, at 22:39:30 UTC (06:39:30 PM EDT; 03:39 PM:30 PDT), another impact was observed by several astronomers throughout the world. Images and a video of the effect (revealed below) were recorded by members of Société Lorraine dAstronomie (SLA) in France.
In 1994, the Comet Shoemaker-Levy 9 (SL9) impacted Jupiter, which had captured the comet shortly prior to (and damaged apart by its gravity). The impact was so effective that it left scars that sustained for months and were more noticeable than Jupiters Great Red Spot.
Since then, astronomers have observed multiple things affecting Jupiter, and it is expected that such impacts happen all the time (though unobserved). Similar to what occurred with SL-9, this object is thought to be the remnant of a larger comet or asteroid that was recorded by Jupiters gravity that broke up shortly prior to the effect took location. Whereas impacts with Jupiter were when thought to be rare, they are now comprehended to be a regular incident.
Light on at Jupiter! Anybody house? This bright effect flash was found yesterday on the giant world by astronomer José Luis Pereira.Not a lot of info on the affecting object yet however its likely to be large and/or fast!Thanks Jupiter for taking the hit?? #PlanetaryDefence pic.twitter.com/XLFzXjW4KQ— ESA Operations (@esaoperations) September 14, 2021
