It's a Solar Cover-Up!
There goes the sun, but it’s all right… it’s just our big ol’ Earth getting in the way of SDO’s view again!
NASA’s Solar Dynamics Observatory normally enjoys an unprecedented and unblinking view of the sun from its position in orbit, but every now and then — for several weeks at a time, in fact — it’s oriented such that our planet passes briefly between its cameras and the sun. This creates, in effect, a daily eclipse event!
The image seen here is from this season’s first such event, captured on Sept. 11 at 6:57 UT by SDO’s AIA 171 camera. The current season will last until Oct. 4. The previous eclipse season ended in April — here’s an image from the AIA 304 camera taken on April 1.
Our atmosphere makes Earth’s silhouette appear hazy.
