Images from the Partial Solar Eclipse of Oct 23rd 2014

Its rare for one to live in a place where the heavens just decide to show you their wonder. The path of Oct 23rds eclipse wen right through Minneapolis, USA where I currently live. Not to miss this, i loaded my scope and filter in the car, and set it up at my workplace’s parking lot right after work. The sight that made the eclipse special was the massive sunspot AR2192 which is as big as Jupiter. As seen from here. the maximum of the eclipse about ~ 50% was able to obscure some part of the sunspot.

Another thing that was interesting was the ability to resolve surface limb features on the moon. Contrary to what one would imagine, the moon has a very rocky terrain, since there is no wind, water or volcanic activity to smooth out the surface. Looking carefully we can see this detail in the images above

Partial Solar Eclipse, Oct 23rd 2014

A partial solar eclipse is going to occur on Oct 3rd, 2014 and unfortunately will not be visible from India. Skywtchers in the United States Mexico and Canada are going to be able to witness this event. The maximum of the eclipse is expected at 9:45pm UTC


Eclipse as Seen from Minnesota, MN, USA at 17:50 CDT

The eclipse will make a good photo shoot event with Venus in the background

Lunar Eclipse, Oct 8th 2014

A total Lunar Eclipse will occur on Oct 8th 2014.The penumbral phase begins at 8:15:33 UTC during broad daylight in India. Moonrise in Delhi will occur at 5:14 IST ( 11:44 UTC ) when the moon will be phase past the U3 umbral-penumbral contact. That means that the maximum extent of the eclipse would be over by the time the moon is visible. However stargazers in India may be able to see the partial phase which will extend into the sunset. The moon will finally come out of the umbral shadow at 7:03 pm ( 13:33 UTC )

Annular Eclipse 2010: Project Shadow

After a very successful Total Solar Eclipse watch on July 22nd. The Amateur Astronomers Association is now packing its bag to go to yet another location to view The Annular Solar Eclipse on January 15, 2010, and this time at an even greater scale.

AAAD this time will be at 4 different locations capturing and showing public this beautiful celestial event

The first team is off to Kanyakumari (at the center line) The Second one at a spot below chennai(the eastern edge of the eclipse line), third at varkala, Kerala(the western edge of the eclipse line)and off course there will be Amitabh Pandey who will be on his mountain bicycle some where between all the teams showing the night sky to the locals (he will join one of the teams on the eclipse day).

The forth and the most important one at The Nehru Planetarium, Delhi in the Teen Murti lawns, doing a Public Sky Watch from here,

As the crowds here can go into thousands.So preparing for it, we are having a dress rehearsal of the eclipse watch on Januaray 3rd, 2010.

All Amateur Astronomers are hereby invited to come for the preparation of the Eclipse Watch (on Jan 3rd)and volunteer for it(on Jan 15th)

The preparation Dress Rehearsal is on Sunday, January 3rd, 2010 ,12 noon onwards:

Be There

Attendance of all participating AAAD members would be mandatory

Pitfalls of an Eclipse Flight, Lessons learnt

It’s easy to be wise after the event- Some wise man

Ok, recently you may have heard a couple of space-nuts chartered a B737 jet to chase the July 22nd eclipse from a height of 41000 feet. I guess considering the monsoon, it was a good idea that would guarantee that you atleast got to see the eclipse. Passengers paid approximately Rs 80,000 for “sun side” seats and Rs 29,000 for “earth side” seats. Personally I don’t know why would I pay to see the sun’s shadow on earth.

From that point of view it was a good idea, considering places like Taregna, Patna, Shanghai and most parts of India got clouded or washed out!

However people on board with cameras and photography equipment will be kicking themselves because of some things that got overlooked. When you dig deep into your pocket for an experience like this a little more research should have gone into it

It may me useful to remember that while shooting from a plane’s windows, ( yes.. in case you forgot, you’re inside the plane and you have to take photos from inside the aircraft’s double paned window, both of which usually have thousands of microscratches) two results are inevitable

The image of a bright object may have double reflections from both window surfaces. Unfortunately this will always be there and playing with the camera focus cannot get rid of it. The sun will be at infinity and the extended light path due to reflection does not affect it. The result??, see for yourself

Look at this picture of totality taken from the eclipse flight, if you look carefully, there is a double reflection glaring at you at the bottom edge of the image. This was a specimen frame drawn from video taken by the BBC media crew on board the flight. We checked this with other videos taken by AAJ TAK etc, which also had the same issue.

There is also a second problem. As mentioned earlier, the windows are usually scratchy and not very clean. It is pretty easy to get rid of these scratches out of focus in the image. However with a eclipse, especially the diamond ring a big quality issue arrives.


The microscratches on the window scatter light in all directions completely ruining the photo. Both images above were taken aboard the eclipse flight.

One of the reports we heard from the people conducting photographic experiments onboard had another unforeseen issue, Apparently the plane went off charted course to bypass some clouds, sending their automation software “Eclipse Orchestrator” haywire

Pity!

If you were careful in reading what I wrote, yes there are CLOUDS at 41000 feet. We got wind of this fact a day before the eclipse. A curious me and Vishnu did ask the Captain of our Spicejet flight to Varanasi when we landed at Babatpur for the eclipse

So if you are serious about taking pictures of totality, you might want to keep these details in mind before swiping that credit card.

AAAD – ECLIPSE REPORT – VARANASI 2009


After the intoxicating cosmic ride, its time to key my thoughts .

Firstly, felicitations to the team including Anindya, Debnath, Puneit, Vidur, Mayank, Himanshu and yours truly!

Varanasi was a special choice to begin with, what with the surreal feel and effervescent life-giving Ganga. The ghats would offer a stunning view should mother nature decide to share our prayers and enthusiasm!

Many thanks to the preliminary group including Anindya, Debnath, Puneit and Himanshu for reaching early and selecting a stunner of a site. The terrace of the Anami Lodge on the Assi Ghat with a panorama of the Ganga and clear horizon across was magnificent. Anindya, our very own banarsi babu deserves special mention for his initmate knowledge annd pulse of the place.

Vidur, thanks for the lovely T-SHIRT design and Raghu, (Team Sasaram), thanks for the execution, both Sasaram and Varanasi had an identity!

The preparation was immense and exhaustive with DSLRs, Video Cameras and “Point and Shoots”. All of us gave our all during the night catching only a few moments of rest. Aside from scouting and selection of the place, our preparations involved elaborate and educated guesswork on the weather (which proved correct!) and timing the set-up of equipment and execution.

21st night provided a clear night sky (who said city skies are bad?) and we spent the time in doing what we love – deep sky observation. We managed good images of the Eagle Nebula, Lagoon Nebula, M6, M7, M45 and other MW objects aside from Jupiter. At 3 a.m., with Venus standing bright and tall, the signs were ominous – we were not going to be denied.

From then on, it was a queer and unadulterated mixture of confidence, hope and hysteria that caracterized the remainder of our solar journey! With the mystic black ((c) Puneit), enveloping the blinding gas ball over sublime grey skies, we all felt enveloped by the power of this magnificent world we inhabit.

Many thanks to Raj mama for his amazing guidance pre-trip (and the polaroid camera (Mayank shot some beauties (no pun intended!)) and Celestron C6 (Sasaram), Wish you were there!

Many thanks to Chinmaya for his enthusiasm pre-trip, Wish you were there too!
Many thanks to Nikhil (friend of CB, great pics!), Sunita, Prof. Ravinder Singh (Univ. of Patiala) and relative (Mirzapur), Amit (TOI) and family, Tushar (and brother and friend), Chitrangada, Tanuj and Manoj (Astronomica) and all others on the terrace for being with us!

Many thanks to Dr. Rathnasree for her untiring efforts for TSE 2009.

Many thanks to Vikrant (@ Patna) for his high pitched super charged voice at 3 a.m., there’s no one quite like you!

Gargantuan felicitations also to the Sasaram team (we are one!) who put in an equal amount of effort if not more!

Lets meet on SUNDAY and rejoice!

Vishnu

PS – Did I mention “divine intervention”

How to make a pinhole projector to safely view the solar eclipse

Materials:

Dark-colored plastic cup
Wax/butter paper
Scissors
Rubber band
Pushpin
a shuttle cork cardboard box (both sides open)
To Do:

Use the pushpin to punch a hole in the center of the cup’s bottom. Cut out a piece of wax paper slightly larger than the cup’s mouth. Stretch this paper across the mouth of the cup. Use a rubber band to secure the paper.
now insert the cup inside the shuttle cork box with the bottom of the cup outside and the side with wax/butter paper inside (see that no light enters from the cup side and there is complete darkness if you see through the other side)
now point the pinhole towards the sun you will see a small dot forming on the butter paper that is the disk of the sun as the eclipse proceeds the sun starts forming a crescent phase

PS NEVER LOOK DIRECTLY TO THE SUN IT DOES NOT MAKE A DIFFERENCE IF ECLIPSE IS ON OR NOT !!!
