. On August 31, 2012, a giant prominence on the Sun erupted, sending out particles and a shock wave that traveled near Earth. This event may have been one of the causes of a third radiation belt that appeared around Earth a few days later, a phenomenon that was observed for the first time by the newly launched Van Allen Probes. This image of the prominence before it erupted was captured by NASA's Solar Dynamics Observatory (SDO). // NASA/SDO/AIA/GSFC

We present the results of an extensive observing campaign on the O7.5 III star xi Persei. The UV observations were obtained with the International Ultraviolet Explorer. xi Per was monitored continuously in October 1994 during 10 days at ultraviolet and visual wavelengths. The ground-based optical observations include magnetic field measurements, HЮБ and He I lambda 6678 spectra, and were partially covered by photometry and polarimetry. ...

Next: Other deconvolution tasks Up: Image Deconvolution Previous: Computation . If you have used multi-frequency synthesis in the imaging stage, you will have to have considered a fly in the ointment - the flux density of the source will vary with frequency (as well as spatially). For detection and low dynamic-range work, mild spectral variation can generally be ignored. ... The Miriad deconvolution task mfclean can be used to avoid this distortion. ...
