Heliographic Latitude (B0) | -0.7° |
Heliographic Longitude (L0) | 46.24° |
Position Angle (P) | +13.06° |
Carrington rotation number (CR) | 2050 |
The Heliographic Latitude (B0) has been decreasing steadily and today it has changed to a negative value. The way I understand it that is the location of the center of the Sun’s disk and means that the north pole of the Sun is now pointed toward Earth and the south pole away from Earth.
Group 929 has the sub to itself today. I don't detect any areas of plage anywhere on the disk.
I have received many reports over the past 24 hours of the heomahneyic events that are taking place in our atmosphere as a result of the X-9 flare from Group 929 earlier in the week, and perhaps additional events about which I am unaware. I saw yesterday that ApaceWeather.com was still showing a 5Dec06 SOHO image as the current image and there was a note in another section saying an instrument had been overwhelmed by recent events.

- Group 929

A southern hemisphere group.
The group looks smaller today than it has in the past. Do they stabilize after giving off a large flare? I see one large umbral spot surrounded by a symmetrical penumbra auth a much smaller spot beneath it, also surrounded be a proportionately smaller penumbra.

I had a good deal of trouble focusing tonight at 43x and eventually gave up on it and did most of my following along with Cherington at 21x. I got interrupted by a friendly security officer and then by a passer by and had trouble getting back on track. By then my toes were cold and fortunately, I was near the end of Cherrington's description for the day.

- Franklin looks very deep
- I identified the Altai Scarp, Thoophilus, Cyrillus, Catherina, and Picolomini
- Stringutl has nice has nice shadow marking the western wall, 2.prominent craters straddle the wall in the E just off the terminator
- Rays still prominent off of Tycho and Copernicus
- Aristarchus appears to have a strong white ray to the west
- Teneriffe Mountains and Straight Range under Plato
- 43x
- The other night I identified Montes Archimedes from Ruukl where Cherrinhton snows Palis Buyrendis
- With the aperture partially occulted I can see Ariatillia and the W rim of Apitzennerg
Using cherrington as a guide I made the following observations:
- Eudoxus and Aristotle are supposed to be prominent but they are faint and I had missed them
- Mare Crisium is gonee but I can still see Peoclua and Maceobia
- Cepheus is nearly 1/2 the distance from Franklin to Atlas
Taruntius in the terminator
