Solar Image: 12 January 2014


Here is today's whole disk image and 3D isophote rendering of the sunspot groups. This will be my last post for now before traveling back to the Andromeda Mobile Planetarium for work. I might get to image again on Saturday or Sunday when I get back to my equipment.

The receding sunspot groups AR 2257 and 2255 have developed gamma-delta magnetic fields putting the risk for M-class flares at 40%, and X-class flares at 10%. As of yesterday only eight C-class flares were released by active regions 2255, 2257, 2260 and 2262; five of which were by AR 2257.

I was hoping I can document the growth and development of AR 2259 [McIntosh: Eko] but it looks like I'll only get to catch up on that via the internet.
AR 2259

Well that's it for the mean time. Catch you guys next time! :)
Clear skies!

Solar Image: 11 January 2015


Here is the solar image for 11 January 2014 along with their 3D rendering of the transiting sunspot groups. I've been able to follow AR 2257 since January 7 and here is a little animated GIF showing the development of AR 2257.

AR 2257 currently has a McIntosh class of Dki and NOAA forecasters estimate a 40% chance of flares. As of this post it released 3 C-class flares today.

Solar Image: 10 January 2015


Today is a bright & sunny Saturday morning. There are several sunspot groups in the Sun today. I've been receiving good feedback for my 3D rendering of transit ARs from the solar imaging community that I've decided to add them to my usual whole disk white-light images (which are now posted at the sidebar of this blog). The 3D render brings out much detail in the umbral and penumbral structure of the sunspot groups.

AR 2257 is growing in size and may pose a threat for M-class flares. It currently has a McIntosh class Dki and released 3 C-class flares yesterday (C 9.6, C 1.8, C 1.9).

Another sunspot group that seems to be growing in size is AR 2259 [Eko] with two C-class flares yesterday.

Comet C/2014 Q2 (Lovejoy)

I've only gotten back in Manila from the holidays and decided to take a shot at comet Lovejoy. I wasn't able to do it earlier since I left my usual gear (camera and travelscope) while away since we didn't have much space in the car. Comet C/2014 Q2 was first spotted by Terry Lovejoy last August.

Anyways, I decided to take out my dobsonian and scanned for the comet which is now in Eridanus. The moon and Manila's light and air pollution made it a bit challenging to observe the stars of Eridanus.

I was able to spot the comet by using omicron eridani (Keid & Beid) as my reference point. These stars were relatively bright and close enough to the comet's current position. I took multiple frames of the comet each at 1.3 seconds only given that my setup had no tracking capacity. Unfortunately I couldn't stack them together either since my laptop had limited memory to run conventional stacking softwares.



I ended up my night by taking a shot at Jupiter and the moon.
