History: (H. Chennaoui Aoudjehane, FSAC, ATTARIK Foundation: A. Aaronson) On Tuesday, 25 August 2020, around 2:30 pm Moroccan time (GMT+1) a fireball was widely witnessed by people in southern Morocco from Alnif, Zagora, Tazarine, and Rich. The fireball trajectory was from the SW to NE. A search was immediately undertaken by local residents and meteorite hunters between Goulmima and Errachidia. Hundreds of people began searching on the same day, and the first piece was found the following day by Alalou Youssef close to his village of Tarda. The fall location is crossed by the national road linking Ouarzazate to Errachidia, and because of the easy access thousands of people soon traveled to the area. National TV channels Al Oula and 2M recorded the activity. A field mission was organized to the fall site on 27 and 28 August 2020, with Dr Mohamed Aoudjehane, Prof. Faouziya Haissen and Prof. Hasnaa Chennaoui (members of the board of directors of ATTARIK Foundation), with the support of Prof. Hicham Si Mhamdi (Faculty of Sciences, Errachidia), Adam Aaronson and members of the Moroccan Association of Meteorites (Ahmed Bouferra, Mohamed and Zaid El Guireh). Several eyewitnesses from areas up to 150 km away were interviewed, and reported three " of a bright yellow, barrel-sized fireball with green edges. The meteor was followed by a thick trail of white smoke that remained suspended for several seconds. The fireball was reported to release little pieces around its edges, witnesses said the fireball was accompanied by a whistle, followed by multiple detonations. One eyewitness reported an almost vertical trajectory. Thousands of small, mostly complete stones were collected ranging from only a few milligrams to 99 g. Many pieces were recovered by hunters using magnets. The strewn field is about 3 km long and situated ~10 km east of Tarda centered at 31.8265°N, 4.6794°W.
