The Sun is leaving Solar Minimum and Entering Solar Max. If you have not, please familiarize yourself with these lectures in preparation for today’s field exercise. While we are at it, please review this lecture on the Carrington Event and Predictive Statistics.
OK, class. These three lectures have been reintroduced so they are in one place and are easily accessible. This way you can amaze your friends and be quite knowledgeable about heliodynamics and space weather in the process. Our grad-ass’ CJ and Lude will be serving the Ethiopian Yrgacheffe and croissants with Trappist preserves this morning while you get up to speed because we have a large inbound CME that is inbound.
From Our Friends at Space Weather:
REVISED FORECAST: The CME launched toward Earth by yesterday’s X-flare is moving faster than originally thought. Analysts at the Goddard Space Weather Lab have revised their forecast accordingly, advancing the cloud’s expected arrival time to 09:17 UT (5:17 am EDT) on Saturday, July 14th. Weekend auroras are likely. Aurora alerts: text, voice.
X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th. Because the sunspot is directly facing Earth, everything about the blast was geoeffective. For one thing, it hurled a coronal mass ejection (CME) directly toward our planet. According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the CME will hit Earth on July 14th around 09:17 UT (+/- 7 hours) and could spark strong geomagnetic storms.
The explosion also strobed Earth with a pulse of extreme UV radiation, shown here in a movie recorded by NASA’s Solar Dynamics Observatory:
