August 22nd, All Quiet...

The above image is a GOES X-ray Flux plot, containing 5-minute averages of solar X-ray output in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary GOES X-ray satellite is shown. As of February 2008, no Secondary GOES X-ray satellite data is available. So some data dropouts will occur during satellite eclipses.

The solar activity for August 21st was very low. There were a few B-class flares. On the labeling front, three new Active Regions were designated: AR 1550, AR 1551, and AR 1552. And several coronal mass ejections (CMEs) were observed, but none are headed toward Earth. Forecast: Solar activity is expected to range from very low to low through August 24th.

Earth's geomagnetic field has been quiet. Forecast: The geomagnetic field is expected to be predominately quiet through August 24th. Stay tuned...
