SOLAR Chromosphere Time Lapse Shows the Sun Activity in Motion on October 2023
Alqueva´s Dark Sky Reserve | By Year: 2023 | Solar Ha | Time Lapses Photography
On 12th of October 2023, I took a solar time lapse of an entire full disc of the sun, showing a lot of interesting features in motion, such as eruptive prominences, filaments, active regions with minor flares, small spicules dancing like hair in the wind, and a delicate waved line of plasma floating hundreds of kilometers above the sun’s surface, stuck by the strong magnetic fields, until has been released into space in a blink of an eye. The video shows the chromosphere while the sun is rotating over the course of 3 hours. The time lapse sequence was captured from Dark Sky® Alqueva territory with a Player One Saturn-M SQR camera and a Lunt telescope LS100, generating 3TB of data. The final result is a 5K high resolution solar movie comprising 246 images over the course of about 3h, between UT11h05 and UT14h08..
PT: Em 12 de outubro de 2023, captei um time lapse do disco solar completo, mostrando muitas características interessantes em movimento, como proeminências eruptivas, filamentos, regiões activas com pequenas flares, espículas dançando como cabelos ao vento e uma delicada linha ondulada de plasma, flutuando centenas de quilómetros acima da superfície do Sol, presa pelos fortes campos magnéticos, até ser liberada para o espaço em um piscar de olhos. O vídeo mostra ainda a cromosfera solar enquanto o sol no seu movimento de rotação, girou ao longo de 3 horas. A sequência de lapso de tempo foi captada a partir do território Dark Sky® Alqueva com uma câmara Player One Saturn-M SQR e um telescópio Lunt LS100, gerando 3 TB de dados. O resultado final é um filme solar de alta resolução 5K composto por 246 imagens ao longo de cerca de 3h, entre UT11h05 e UT14h08.
