This extraordinary bolide was spotted from Spain on March 16, at 2:54 local time (equivalent to 1:54 universal time). It was brighter than the full Moon. The event was generated by a rock (a meteoroid) from an asteroid that hit the atmosphere at about 61,000 km/h. The fireball overflew Portugal. It began at an altitude of about 91 km over Foros de Vale Figueira (west of the region of Évora), moved northeast, and ended at a height of around 19 km over Cano (south of region of Alentejo). The preliminary analysis of this event shows that the rock was not fully destroyed: a part of the meteoroid survived and reached the ground as a meteorite. This bright meteor was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN) from the meteor-observing stations located at Huelva, La Hita (Toledo), Calar Alto, Sierra Nevada, La Sagra (Granada), and Sevilla. The event has been analyzed by the team headed by Dr. Jose M. Madiedo (principal investigator of the SMART project), from the Institute of Astrophysics of Andalusia (IAA-CSIC).

O céu de março de 2024

Este mês tivemos a ideia de vos recordar os principais eventos astronómicos que vão ocorrer nos céus portugueses e enviar-vos um pequeno resumo para que possam planear com mais tempo as vossas observações.

8 de março: Lua próxima de Marte e Vênus

Perto da fase da Lua Nova, poderá ver os planetas brilhantes perto do nosso satélite natural. Este evento astronômico é difícil de ver, pois os objetos celestes estarão próximos ao Sol, e você precisará de alguma destreza para localizá-los no céu.

14 de março: Lua próxima a Júpiter

Um evento mais notável ocorrerá uma semana depois. Júpiter e a Lua iluminada em 16% encontrar-se-ão em Carneiro, surgindo após o pôr do sol. Observadores com binóculos poderão ver Urano nas proximidades.

20 de março: Equinócio

Um importante fenômeno astronômico acontece este mês — um equinócio! O primeiro dia de uma nova estação e o dia com horas iguais de luz do dia e noite.

24 de março: Mercúrio em posição favorável de observação

Raramente visível, o pequeno Mercúrio está bem localizado para observação, pouco depois do sol se pôr.

25 de março: Eclipse lunar penumbral

Prepare-se para o primeiro eclipse lunar do ano! Um eclipse lunar penumbral é o tipo mais subtil de eclipse lunar, um que a maioria das pessoas nem sequer notará. Mas você verá este eclipse se souber quando e onde olhar.

*Global Event:*	Penumbral Lunar Eclipse
*Local Type:*	Penumbral Lunar Eclipse in Lisbon, Lisbon
*Begins:*	Seg, 25 de Mar de 2024, 4:53
*Maximum:*	Seg, 25 de Mar de 2024, 6:36 -0,213 Magnitude
*Ends:*	Seg, 25 de Mar de 2024, 6:39
*Duration:*	1 hour, 46 minutes

31 de março: Cometa 12P/Pons-Brooks próximo a Hamal em Carneiro.

O cometa 12P/Pons-Brooks, vai ser fácil de localizar com binóculos, perto da estrela mais brilhante em Carneiro no final do mês

Perihelion: April 21 (0.8 a.u.) / Orbital period: 71.3 years
Closest approach to Earth: June 2 (1.6 a.u.)
Best viewing window: At nightfall, February through mid-April. Also visible just before dawn in February.
Expected peak magnitude: 4 in early April

Source: Sky and Telescope

Asteróides em oposição

3 de março de 2024: 3 Juno (mag 8.6), constelação Leo.
12 de março de 2024: 23 Thalia (mag 9.7), constelação Leo.

Esperando que esta informação seja útil e do vosso agrado, era bom darem-nos algum feed-back para que possamos avaliar a recetividade da mesma. Estejam à vontade para sugerir melhorias que sempre que possível serão consideradas.

Noites estreladas.
