The Disappearing Sun

It’s eclipse season for the Solar Dynamics Observatory! Twice a year near each equinox, the orbital dynamics lines up so that from SDO’s vantage point, the Earth passes between SDO and the Sun. Eclipse season lasts for about three weeks and each eclipse can last up to 72 minutes in the middle of an eclipse season. This current eclipse season started on September 11 and lasts until October 4. There’s no way to avoid the loss of images, the SDO team says, but the continuous contact with the ground station SDO’s orbit allows was judged to outweigh the loss of some images.
