The sky this morning is partly hazy with some clouds. Seeing condition is not that good as well :( AR11907 Sunspot Group so far is the largest group on the Sun but the upcoming possible AR11909 Sunspot Group that is near the SE limb is quite prominent and might surpass AR11907 Sunspot Group in size in the days to come after it exits Wilson Effect. As I was trying to image in Ha wavelength, clouds started to obstruct the Sun and I was only able to image a huge looped prominence visible in the NW limb through passing clouds before I got totally clouded out :( Nice to see the Sun again after more than a week :)

After resting yesterday from doing any imaging session after Caliraya due to possible stress out from sleepless nights,I was able to do solar imaging session again this morning and was greeted by AR11899 Sunspot Group by providing me an almost perfect seeing even for a short time period :) LOL Details from this group is amazing and so far the best from my previous imaging of the same group in the past few days.... How I wish it was constant daily. But after getting a fantastic view, nature told me I had enough and revert me back to regular seeing after imaging AR11899 Sunspot Group by providing me a more or less good seeing for me t image AR11896 and and 11893 Sunspot Groups. I was also able to do some decent work under good seeing in Ha wavelength for me to image AR11899 Sunspot Group as well as a nice large eruptive prominence visible in the NW limb.

I together with fellow ALPers Andrew Ian Chan and Iah Serna went to Caliraya, Laguna to try to image Comet 2013 R1 Lovejoy and Comet 2012 S1 ISON under dark skies. We went to the site shortly passed midnight as no point going there early as there is an almost full Moon night. The weather was partly cloudy and we had a hard time getting a good polar alignment as Polaris plays hide and seek with us the entire session.:( It was almost passed 3:45am before we got some thinning of the clouds near zenith for us to image Comet 2013 R1 Lovejoy through small clearings. Unfortunately, since there was several short instances of short burst of moderate drizzles, the soil was a bit soft and both of us had problems of star drift for longer exposure. From my several image of this comet, most are trailed bad and was only able to get a short 30 sec decent shot of the comet. :( Comet Lovejoy was imaged using Canon EOS 500D DSLR on Canon EF100-400mm f/4.5-5.6 IS L lens set at 400mm f5.6 at 30 sec exposure at ISO1600 on Kenko Sky Memo-R tracker. As for Comet 2012 S1 ISON, the clouds did not cooperate with us till it was around 5:15am already thus exposure are mostly washout and useless IMHO. Nevertheless, we are still happy that we were able to still observe the 2 bright comets. We were also able to see 2 nice rainbows namely one Moonbow and another good bright full rainbow as we were heading home in the morning along the road.
The sky this morning is clear and seeing is very good. AR11899 Sunspot Group continues to show its beauty and maintaining its size. AR11897 Sunspot Group has here is a huge eruptive prominence visible in the NW limb! AR11899 Sunspot Group also has some flare activity inside its core with also a nice large faint eruptive prominence visible in the NE limb. Overall, today's solar session is very good indeed IMHO.

After a failed attempt to do lunar imaging yesterday, I was able to get a chance to do some lunar imaging testing with the ZWO ASI120MM webcam once again. Unfortunately, seeing condition is not good as image is shimmering all through out the session :( I use both single and double stacked 2x barlow lens to do some close up shots of known crater region. I also took a full disk shot of the waxing gibbous Moon before ending my imaging session.

The sky this morning is partly cloudy and hazy as well. Nevertheless , I still setup and check out the Sun on the developments of huge AR11899 and 11897 Sunspot Groups. Seeing condition was a bit poor than yesterday as image is a bit shimmering but I still proceeded to try to get some decent shots before I got clouded out after imaging both of them :( Oh well, better than nothing ...
The sky this morning is partly hazy but seeing is not bad. There are 2 huge sunspot groups on the Sun with AR11899 Sunspot Group leading the way in the NE quadrant in terms of umbra size followed by AR11897 which is large in terms of area. Lots of nice sunspot are also visible on the Sun namely AR11895. 11896 & 11893 Sunspot groups. BTW, AR11899 Sunspot Group is now a naked eye Sunspot Group (Caution: Do not look directly at the Sun without safe solar filter or else eye damage and blindness will occur.) Once large AR11890 Sunspot Group is about to exit the SW limb today as well. I was only able to image the Sun's NE quadrant in Ha wavelength which consists of Huge AR11899 & 11896 Sunspot Groups as well as a large eruptive prominence before clouds cover the Sun :( Oh well, still a nice solar imaging session nevertheless.
