The sky this afternoon is hazy and seeing condition is poor. AR2715 Sunspot Group is very active and has a lots of flaring activity inside its core. Departing AR2713 Sunspot Group is a bit quiet as it nears the western limb. I wasn't able to image in white light as clouds started to cover up the Sun. :( Better luck again tomorrow.

The sky this afternoon is clear and seeing condition is good. AR2712 Sunspot Group is nearing the NW limb but still producing some nice flaring activity inside its core. There is also a large hedgerow prominence visible int he SE limb. A huge, long plage is also developing in the NE quadrant that might develop into an active region in the days to come.

The sky this afternoon is a bit cloudy and I initially thought that it is another bad day for solar imaging. But after a hard rain, the sky started to open up a bit but unfortunately, the Sun is starting to get low in the western horizon but I still proceeded to do a short imaging session on the new AR2712 Sunspot Group as well as a nice large Hedgerow prominence in the SE limb. Seeing condition is poor as expected because of the Sun's low elevation already but I'm still happy with the result nevertheless.

The sky this afternoon is partly cloudy and I have to fight the clouds for almost 3 hours under the heat if the Sun to get some decent shot of the Sun in Ha wavelength. 2 sunspot groups are visible with AR2709 Sunspot Group the slightly more prominent one than the departing AR2708 Sunspot Group which is near the western limb already. Both in white light are quite small and very inconspicious with pore light structure only. 2 nice prominences are visible in the NW and SW limb. There is also a possible new active region developing in between AR2709 and 2708 Sunspot Groups as it has some plage developing. I also use my old reliable TV-101 refractor for this session as it has been a very long while since I had used it so its a good time to let it taste the heat of the Sun once again.

Jupiter is at Opposition this evening so despite the fact that we here in the Philippines will be observing the boring side of Jupiter sans the Great Red Spot and Oval BA, I still try to setup and image tonight. Seeing condition is poor tonight. I was able to let the scope cool down for about an hour. Oh well, better luck this coming weekend again :0

Jupiter Imaging Session - May 6, 2018 The sky this evening is partly cloudy but I proceeded to try to image planet Jupiter with the Meade 8" f/10 SCT using ZWO ASI120MM webcam with 2x barlow lens and RGB filters. Seeing condition is not that good but I still proceeded after letting the scope cool down for almost 1.5 hours . The Great Red Spot is visible nearing Central Meridian, I also got to test my new Starbook-S which I locally made and it is working ok. I packed up after 3am feeling very tired but still happy that I was able to image Jupiter. I was planning to image Saturn and Mars as well but unfortunately, my Starbook-S battery run out so better luck next time.

I got to image the Summer Milky Way last April 15, 2018 under the dark skies of Caliraya , Laguna using Canon EOS M6 mirrorless camera on Canon EF-M 15-45mm f/3.5-6.3 lens set at 15mm f/3.5 mounted on Vixen Polarie star tracker. Total 7 minutes exposure at ISO 1600.

I got to test my old ATIK 16HR CCD camera to test image on the Quarter Moon mounted on Canon EF100-400mm f/4.5-5.6 IS L lens. My purpose to use it is to rehearse myself once again on how to use it. Also, I want to test on the new heat pads that I mounted near the camera sensor to see if it helps eliminate the frosting problem on this CCD as there is no Temperature Set Point on this old camera. After running it more than 1.5 hours, no frost on the CCD sensor so far so I guess it might be working. Looking forward to finally again use it since 2016. I also found out that this sensitive camera is prone to light bleeding if used on a bright subject such as the Moon so I tried using a red filter but I still get some light bleeding a bit but is a bit better than without any filter installed to dim the Moon further. Anyway, the bleeding was further removed with some processing. The session run quite ok and I'm very happy on the result so Im looking forward to the next Caliraya session in March and hopefully get some deep sky images there.

The sky this afternoon is partly cloudy and seeing condition is poor. AR2699 Sunspot Group is about to exit the western limb in a day or two so solar activity is expected to lower down once again without a new sunspot group emerging from the eastern limb tentatively.

The sky this afternoon is clear but very hazy. Seeing condition is also very poor. AR2699 Sunspot Group continues to develop slowly. and flaring activity is starting to mellow down. No big prominences are visible on the disk as well :(

The sky this afternoon is partly cloudy and hazy. Seeing condition is fair. Finally some new moderate size sunspot is visible now and designated as AR2699 Sunspot Group. Some flaring activity inside its core structure while it is also nice to view in white light as well. Hope this group develop some more in its structure.

The sky this afternoon was partly cloudy but ALPer Mike Enage and I got to meet in the afternoon for a solar session as he wants to get into solar observation and imaging this year. Since the Sun is bare with no sunspots visible, we observe the Sun in Ha wavelength. There is a large eruptive prominence in the SE limb and aside from this prominence, the Sun is awfully very quiet :(

Last January 31, 2018, I, together with members of Astronomical League of the Philippines (ALP) went to SM By The Bay , SM Mall of Asia, Pasay City to do a free public viewing session as well as observe and image the Total Lunar Eclipse / Blue Moon / Super Perigee Moon / Blood Moon. I used a Canon EOS 400D DSLR with Canon EF100-400mm f/4.5-5.6 IS L lens set at 400mm f/11 mounted on a Kenko Sky Memo-R star tracker to document the eclipse. More than 10 telescopes were set up by ALP members with more than 2500+ people got the witness the eclipse live through various telescopes.

2018 will have 2 lunar eclipses visible in the Philippines. The first one which will occur on January 31, 2018 will be visible in the Philippines as well as most of Asia and the Pacific. Eclipse will start at around 6:50pm PST (Philippine Standard Time) when the Moon will enter the Earth's light shadow (penumbra). Partial eclipse will begin at around 7:48pm and enters totality at around 8:51pm. Maximum totality will occur at around 9:30pm when the Moon is roughly about 51 degrees above the eastern horizon. During totality, the eclipsed Moon will not be very dark as it crossed halfway south of Earth's dark shadow (Umbra) thus will show a light orange Moon at maximum totality. Totality lasts a generous 77 minutes, while the whole partial phase lasts about 3.5 hours more or less. Totality then ends at around 10:08pm an partial phases will continue till around 11:12pm before the Moon totally exits the Earth's light shadow by 12:10am the next day signalling the end of the eclipse. The next lunar eclipse will happen on July 28, 2018. For those who wants to observe or image the eclipse, best location to select is to have a clear eastern view as the event will entirely be in the eastern area.

The sky this afternoon s clear but seeing condition is fair. Not much solar activity past few months already and today's huge faint eruptive prominence in the SE limb gives some hope for some bigger solar activity hopefully this year but I think the prediction will still be a so so solar activity this year.

The sky this early morning is clear and seeing condition is good. KC and I went to our roof deck to try to image the biggest Super Perigee Moon for the year 2018 using Canon EOS 500D DSLR with Canon EF100-400mm f/4.5-5.6 IS L lens set at 400mm f/11 with 1/250sec exposure at ISO 100 on sturdy tripod.
