The Moon passed between SDO and the Sun from 1331-1556 UTC (8:31-1056 am ET). At 2.5 hours in length, it was the longest lunar transit so far in the SDO mission. This still was taken at 14:58 UT, just about when the Moon was centered against the Sun. The image combines individual frames from two wavelengths of extreme ultraviolet light (the 304 Angstrom and the 171 Angstrom channels) taken at the same time.
