Good morning/evening folks, Solar wind speed: 560.6 km/sec density: 1.7 protons/cm3 Planetary K-index Now: Kp= 2 quiet 24-hr max: Kp= 3 quiet C5.2 Flare in progress at time of report from AR2172. Here is an updated look at the visible solar disk on Sunday. Solar activity during the past 24 hours was low with only minor C-Class flares detected. The source of much of this activity, region 2172, continues to rotate into view off the east limb. Although still close to the limb, the active region appears to have a Beta-Gamma magnetic layout and will be a threat for an isolated M-Flare. Also located in the southeast quadrant, region 2171 showed minor spot development within the center of the group and will be a threat for at least C-Class solar flares. All other visible regions are currently stable. AURORAS LOVE EQUINOXES: On Sept. 23th the sun will cross the celestial equator heading south, marking the end of northern summer. Thats good news for high-latitude sky watchers because, for reasons researchers do not fully understand, auroras love equinoxes. At this time of year when the seasons are changing, even gentle gusts of solar wind can spark a nice display of Northern Lights: Enjoy the rest of the weekend.
