Colossal Sun Spot AR3576 Cluster (Márcio Spínola)

Colossal Sun Spot AR3576 Cluster

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

This sunspot cluster AR3576 was captured through a 2nm narrowband filter at the wavelength of 430.3 nm 2. Stunning colossal sunspots, some larger than Earth, can be seen in this image which comes with an appropriate scale of reference. This G-band filter offers great contrast to the photosphere, in this case through a long focal length telescope with reasonable to good seeing as it can be this Carnival morning here in Rio.

This type of phenomenon can generate solar flares of Class M, Class X and and pose some threats, such as radio signal blackouts, create some electronic problems in satellites and impressive geomagnetic storms if coronal mass ejection phenomena also occur towards Earth. Scientists at the Space Weather Prediction Center (NOAA) continue to monitor how the extent and complexity of the structure of the magnetic configuration can produce such explosions.

Este aglomerado de manchas solares AR3576 foi capturado através de um filtro de banda estreita de 2nm no comprimento de onda de 430,3 nm 2. Impressionantes manchas solares colossais, algumas maiores que a Terra, podem ser vistas nesta imagem que acompanha uma escala apropriada de referência. Este filtro de banda G oferece um ótimo contraste para a fotosfera, no caso através de um telescópio de longa distância focal com seeing de razoável para bom como pode ser nesta nesta manhã de Carnaval aqui no Rio.

Este tipo de fenômeno pode gerar erupções solares de Classe M, Classe X e representar algumas ameaças, como apagões de sinal de rádio, criar alguns problemas eletrônicos em satélites e impressionantes tempestades geomagnéticas se também ocorrer fenômenos de ejeção de massa coronal na direção da Terra. Cientistas do Centro de Previsão do Clima Espacial (NOAA) continuam monitorando uma vez que a extensão e a complexidade da estrutura da configuração magnética podem produzir tais explosões.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
