Nasa’s sun-watch satellite tv for pc, the Photo voltaic Dynamics Observatory (SDO), captured a total solar eclipse in area on Sunday (11 February). The eclipse occurred when the Earth handed between the spacecraft and the solar, utterly hiding the solar’s view from the SDO. This is called a transit and it lasted round 31 minutes and coated the complete face of the solar.
The whole photo voltaic eclipsed kicked off the SDO’s bi-annual eclipse season that lasts for round three weeks. The phenomenon additionally marked the mission’s eighth anniversary. The SDO’s eclipse season comes twice a 12 months close to the equinoxes when the Earth blocks the spacecraft’s view of the sun for a quick time frame daily.
Not like the just lately captured complete photo voltaic eclipse, which solely lasted for 31 minutes, later within the season, eclipses can final greater than an hour. Nonetheless, because the eclipse season winds down, the length of eclipses will as soon as once more shorten.
“The eclipses are pretty quick close to the start and finish of the season however ramp as much as 72 minutes within the center,” Nasa stated in a weblog. The SDO’s spring eclipse season started on 10 February and can finish on 5 March.
The SDO, in line with Nasa, watches the solar practically 24/7 from area. The spacecraft’s orbit has been designed to maximise the quantity of information it may ship to the Earth. Though the spacecraft was initially designed for a five-year mission, the SDO has efficiently surpassed its preliminary mission life and simply celebrated its eighth launch anniversary. The SDO’s mission cannot solely assist scientists higher perceive the solar but in addition assist researchers study extra about and even presumably study to foretell area climate.
