Around 1 am I could see the outline of the full Moon shining through the low cloud deck. The transparency was horrible, it was snowing and the wind made the subfreezing conditions even worst. Around 1:41 EST (06:41UT) I took a few images of the partial phase before the clouds thickened and completely obscured the Moon for the rest of the night. 1/100-second, f/8, ISO 800.

This happens on average, once every 18 years. Perigee is the point at which the Moon is closest in its orbit to the Earth and syzygy is a full or new moon, when the Earth, the Moon and the Sun are aligned.

(click image to view & discuss)	Aurora – September 26, 2011 That evening’s Planetary Kp index from the USAF Space Forecast Center was forecast to be in the range of 6-8 which meant that it was possible to see auroras at our latitude (Massachusetts). After sunset, I drove to a nearby location that afforded a northern horizon and set up my DSLR on a tripod. I took over thirty images hoping that the camera would capture the aurora. The sky was washed out by the lights of Nashua, Lowell and other towns in the area due to the high humidity levels. At 21:49 hrs EDT (9:49 pm) I noticed reddish vertical streaks in my image but they were invisible to the naked eye. I continued to image until the clouds and fog rolled in at around 23:00 hrs EDT (11 pm). 30-second image, EF 24-105mm at 40mm f/4, Unmodified Canon T1i, ISO 800, processed with Adobe Photoshop. 21: 49 hrs, 26 September 2011, Littleton, MA.

This active region unleashed an M5-class flare while it transited the face of the sun and its 160,000 km size was greater then a dozen Earth diameters. Sunspots are temporary features in the Sun’s photosphere that are caused by intense magnetic field lines emerging from the interior. The spot appear dark because it is relatively cooler then the surrounding photosphere. The temperature of the spot is still approximately 4500 Kelvin.

Notice that the star has turned to a reddish color. The energy from the nova is being absorbed by the surrounding material and is being re-emitted in the Hydrogen-alpha wavelength. This energy is also being spread out over a larger area and it is causing a temperature drop. The materials that were blasted out are starting to condense and the light is getting absorbed by that material.

(click image to view & discuss)	Comet C/2012 S1 (ISON) - November 15, 2013 Comet C/2012 S1 (ISON) was still rising early enough to clear the trees (approximately 7-degrees altitude) at the Clubhouse before astronomical twilight. Looking E-SE, I still had to contend with local light pollution on the horizon as well as partly cloudy conditions that morning. The comet was still a binocular object under the local sky at the Clubhouse. 5 images x 35-second subframes, Total= 2.9 minutes.

Using a quarter field “Region of Interest (ROI)” setting, I imaged the coma region of Comet ISON.  The image is a bit noisy since I was only able to get 2 images due to clouds obscuring the comet. 2 images x 120-second subframes, Total= 2-minutes.

(click image to view & discuss)	Comet C/2012 S1 (ISON) Enlarged - November 20, 2013 Comet C/2012 S1 has become much brighter since my last image on Nov. 15. The wind gusts that accompanied us that morning made it difficult to set up and image the comet. Fortunately, I was able to block some of the wind by moving my tripod close to a nearby barn. Unfortunately, I had to image in astronomical twilight again. Twilight and moonlight reduced the contrast and washed away any details in the tail. The image is cropped and covers a field of 4.2 x 2.8 degrees. 6 images x 37-second subframes, Total= 3.7 minutes.

(click image to view & discuss)	Messier 33 Galaxy I took this image while I was waiting for Comet Lovejoy to clear the trees on the eastern horizon. M 33, in the constellation of Triangulum, is the third largest galaxy in our Local Group (after our Milky Way and M31, the Andromeda galaxy). It is 3 million light years away and is approximately 73 x 45 arc minutes in size. It is possible to view with the naked eye under extremely, exceptional seeing and transparency conditions with no light pollution. The large reddish nebula in the outer spiral arm is the HII (ionized hydrogen) region, NGC 604. Near the core you can see the HII region NGC 595. 30 images x 210-second subframes, Total= 105-minutes.

(click image to view & discuss)	Comet Lovejoy (C/2014 Q2) in the constellation of Columba It is the 5th comet discovered by the Australian amateur astronomer, Terry Lovejoy using an 8-inch telescope. This comet has a very long orbital period of 11,500 years. In December and January 2014/2015, Lovejoy is rising from the South and will be getting higher as it approaches perihelion on January 30th. On January 1, 2015, Comet Lovejoy is in the constellation of Lepus and is visually a 5.6-magnitude glowing fuzz ball in moderately sized telescopes. A faint tail can be glimpsed in larger scopes (ie. S.C’s 18-inch Dob.). 30 images x 45-second subframes, Total= 22.5-minutes.
