I didn’t do any solar imaging yesterday because of extensive cirrus and cumulus cloud cover. Later, we had a cool front move in, and we got a sprinkle of raindrops. Today the high was a mere 98F – well below the 106-109F we’ve had for most of the past week. We may need to break out the sweaters soon. 🙂
Today, the sun looked like this:
There are new sunspot groups on the eastern (left) limb (edge), and the names of new sunspot groups have now gone from AR37-something to AR3800 and beyond. There are remarkable prominences at both poles, and in both east and west solar limbs.
The sun has been quite active the last 24-hours with solar flares (electromagnetic discharges) causing radio blackouts in the Pacific. These discharges have arisen from several of the plages (bright white areas) around some of the sunspot groups (AR3800 in the southern hemisphere and AR3801 on the equator near the eastern limb).
Some of the prominences are featured below. The one seen on the Southwestern solar limb is remarkable in that it arises from the solar disk and projects a jet of solar material upward into the sun’s Corona.
The featured sunspot groups appear below.
Sunspot group AR3800 is discernable only as its surrounding plage at the bottom of the rightmost frame.
