Solar Imaging Session - March 8, 2010 (Numerous Dark Filaments)

Hello:

The sky this morning was partly cloudy so I was only able to image the NE limb of the Sun only. The long dark filament that was visible in the NE limb is starting to breakup already compared to yesterday's image. The dark filament was estimated to be more or less around 50,000 km from end to end!

Below is yesterday's image of the same dark filament from one I took today. See the slight detachment of the dark filament from the NE limb.

We will see if the long dark filament will still be visible tomorrow................. :0

Solar Imaging Session - March 7, 2010 (Numerous Dark Filaments)

Hello:

The sky this morning was a bit cloudy and I patiently waited for the clouds to persist as I want to monitor the long dark filament that I saw yesterday at the NE limb. Although I can see it in my monitor screen, I wasn't able to image the Sun till past lunchtime! I have to bring all my solar setup down to the laundry area for me to image the Sun at that time!

As I train the PST-Ha at the Sun, I was surprised to see a large bright eruptive prominence in the western limb which I didn't see in the morning. The changes in that prominence was very fast as the prominence changed structure in less than 13 minutes!

After imaging the said prominence, I went back to image the NE limb wherein the large dark filament together with some small dark filaments are visible. Small residual traces of AR 11051 can still be seen near the NW limb.

Hello:

With AR 11051 Sunspot Group totally decayed, only AR 11052 and AR 11053 Sunspot Groups are the sunspot groups left visible on the solar limb. And with both of them at the extreme edge of the SW limb, tomorrow might be another "sunspot-less day" for the third time this year :(

Amid the disappearance of the sunspot groups, numerous dark filaments replaced the sunspot groups on the surface of the Sun today. The most beautiful one being on the NE limb :)

Hello:

The sky this morning is ok and seeing is again fair. AR 11045 Sunspot Group had deteriorated already but in Ha light, I could still see some small activity as well as a nice S shaped Dark Filament behind the group. A large eruptive prominences can also be seen near the group in the NE limb.

AR 11051 has also shrunk and activity even in Ha light is also very minimal :( But AR 11052 and AR 11053 Sunspot Groups , although small in size, are very active with lots of bright plages as the 2 groups are near the SW limb already.

Overall, activity in the Sun is starting to calm down a bit in terms of number of large eruptive prominences compared to 2 weeks ago.

Solar Imaging Session - March 3, 2010

Hello:

Today's solar activity is a bit bore with AR 11051 Sunspot Group showing some small activity inside its core while AR 11052 and AR 11053 Sunspot Group looks the same as yesterday's image.

AR 11045 Sunspot Group didn't get its new AR 11054 designation yet as it seems it lose all its sunspot group but the group still shows some small activity inside its core. A moderate sized eruptive prominence can be seen near the AR 11045 limb area.

Solar Imaging Session - March 2, 2010 (3 New Sunspot Groups)

Hello:

The sky this morning is again clear and seeing is fair. AR 11051 Sunspot Group is starting to lose its activity inside its core . Solar prominences today are also not that big :( But today's attention turn to returning AR 11045 Sunspot Group (newly designated AR 11054) near the NE limb as well as 2 new sunspot group , AR 11052 and AR 11053 , near the SW limb.

Hoping these new groups will grow in size in the days to come.

Solar Imaging Session - March 1, 2010

Hello:

The sky this morning is fair. The Sun this morning is a bit quiet as most of the large eruptive prominences are all gone except for a moderate sized eruptive prominence that is visible in the NW limb. AR 11051 still display some activities inside its core.
