Dear friends of Science, Astronomy and all kutchies.

Shadows to disappear from Middle of KUTCH and Middle of India on tropic of
CANCER

As an effect of an astronomical event called 'Zenithal Sun', people living at
the places located on particular latitudes will come across an event, in which
the shadow of an object will vanish from the earth for few seconds during
a particular time, depending upon the declination of the sun.


"The scientific reason behind this event is related with the position of our
Earth which is tilted at 23.45 degree because of which, the sun moves up to
23.45
maximum at north. Sun and Earth come at such position, where shadow becomes too
narrow and seems almost
disappeared. For this reason, people residing at the places falling at
particular latitudes can see such event twice in a year BUT HERE ONLY ONCE in a
YEAR . Most of the people
don't know about such event. It is a wonderful opportunity to experience such
event as SUN REACHES 23.45 NORTH MAXIMUM on 21 JUNE 05:45 AM = IST 11:15 AM =
12:07 BHUJ LOCAL TIME. BUT AS SUN Transit the Meridian at 12:52 in BHUJ the
phenomenon happens at BHUJ at 12:52 PM IST

Information of SUN on 21 June 2009

Declination: +23° 26' 21.5" Constellation: Taurus

Altitude: 67° 34' 58" Azimuth: 82° 13' 3"

Rise: 6h 8m 15s Transit: 12h 53m 10s Set: 19h 38m 5s


Information of MOON on 21 June 2009

Right ascension: 4h 21m 16.17s
Declination: +25° 46' 32.1"
Constellation: Taurus

Altitude: 86° 27' 26"
Azimuth: 354° 47' 20"

Rise: 4h 13m 5s
Transit: 11h 14m 18s
Set: 18h 17m 53s

On June 21, at 12:52 pm, shadows of objects will vanish for a few seconds. With
the rotation of Earth, other places falling in the particular latitude will
witness this event.

People
of Kutch are preparing for ASHADHI BIJ (ASHAD SUD2-JUNE24 Though RATH
YATRA will be held on ASHAD SUD3-JUNE25) years 2009 as Kutchi NEW year
2065/66 (kutchi year may not have started before Vikram Sanvant started) and all
kutchi from all over the world will gather in KUTCH to
celebrate the NEW year. But Kutchi astronomers will celebrate double
celebrations. So wish both astronomers and Kutchies get to gather for
combined double celebrations with Kutchi HINDOLA in Swaminarayan
temples.


Simultaneously
JUST after 4 weeks ASHAD AMAVASHYA-JULY22 celebration as year 2009 is
also will be celebrated as INTERNATIONAL ASTRONOMY YEAR and as the
great astronomical phenomenon of TOTAL SOLAR ECLIPSE in the year 2009
is in INDIA starting from Saurashtra, south of GUJARAT and crossing
middle of India on Tropic of CANCER. 22
July 2009 is waiting to celebrate in INDIA , and the year 2009 is the
international Astronomy year. let us celebarte together all together.
Places of Gujarat, astronomy clubs of that area of near Eclipse centre line near
areas of the Bay of CAMBAY.

Since we had Venus transit activity in
India we are waiting for an another golden opportunity of Total eclipse
locally passing through the middle of India and Indian continental
region. That will give the maximum advantage to study for Sun Eclipse
to the maximum Local people of India and from all over the world to
come to India.

Since it has starting point @ SE region of
Saurashtra around Bhavnagar and Mahuva beach area and crossing south
Gujarat - Surat and MP, UP, Bangol and Assam it will give advantage to
people around to study the phenomenon locally at their own home place.
we encourage local people, schools and science institutes to
participate and share their knowledge and experience during this time
and give and take maximum benefit of the study of the SUN Eclipse study
opportunity.

Luckily both the place Bhavnagar and Surat
of Gujarat have Science teaching institutes and university. we
encourage people from the concerned department come forward and start
an astronomical activity in and advance to create interest in local
people and students. so bye the time they are well aware of the
importance of the Astronomical phenomenon and train them for the study
of the subject.

Dear Science and astronomy Friends,
Happy summer solstice

Today is 20 June and tomorrow on 21 June - at local time 12 PM (which is IST
12:52 for BHUJ) - sun will be over head on tropic of cancer - need to take
picture of RAMKUND steps in PLUM line direction to show if the structures has
any shadow at that time in any direction? (for MODHERA or at the KONARK temples
at the their LOCAL NOON time) those who wants to do the experiments on the
tropic of cancer to find out where is the real tropic of cancer and also to
measure the size of the Earth.

http://in.groups.yahoo.com/group/scienceclubofindia/files/MeasureEarth.doc
http://in.groups.yahoo.com/group/scienceclubofindia/lists/

Hints: as Calculation of AU with the help of Venus transit we need to measure
Earth First in reality rather than just taking it granted. As on the summer
solstice day The sun is on the 23.45 N, (Not the 23.5 N - which makes about 3km
difference in distance) we need to go there and find actual place on 23.45 on
the day at local time 12:00 NOON. And that will be real practical aspect rather
than just taken granted Last discussion time.

June 2009) : Measuring the Earth:



Sub: How long will it take and how far we need to go to measure the Earth?
Similar to the experiment below, But all need to do is use local time. When sun
comes overhead (No east or No West). And select two place A & B of Maximum
possible distance apart NORTH and SOUTH and do the measurement same time at both
place as follows.

We can use one control place “S” in South or “N” in North about 50 Km away to
correct any minor errors from short distance “few KM” experiment.

Similar Example of Latitudes longitude finding at the Local time. – for tropic
of cancer @ Local time you need to find the correct time when sun is on the head
with no shadows East or West. and need to be there at LOCAL time of 12:00 NOON
which may be 12 + MM depending on the place where you go – Longitudes.

Experiments done at the Place A & B (NEAR 23.45 N) on 12 Noon IST will have
shadow towards East/West. Depending your positions in India (West/ East of 82.5
E Longitude). And so accordingly you will get shadow East/West. Measure the
length of that of shadow of 3 Meter pole OR a PLUM LINE shadow and find the
Tangent = shadow/ pole - will give u the angle. Say example : shadow = 600 mm at
that time. So 600/3000= 0.2
so anti tangent is an angle of 11.30' degree. so you are 11..30' West/East of
IST line means IF shadow is East than you are WEST and at 82.30' - 11.30' = 71
degree East longitude.

(If shadow is in the EAST than - you are IN the East of the TIME LINE so you
need to Start an experiment a DAY BEFORE (20 JUNE) and repeated on 21st JUNE
before 2 hours before 12 IST and preferably to start more than an hour before to
set up all arrangements)



Now you find exact time when to take results of the experiment. when there is no
shadow to the EAST/WEST - at 12Noon + (11.3o' x4) = @12 + 46 PM Here you have 46
minutes to do that. To take the next accurate place readings. When there is no
shadow in East/West but to the NORTH/SOUTH ONLY (depending your position North
or south of the SUN in India or in the world) at that place at that time. GPS
may be in correct to show that but not the SUN.

Now measure the length of the shadow in accuracy of mm fractions. @ places “A”,
“B” & “N” or “S”@ the same time. If the Difference of the length of shadow is
1mm at places “A” and “B” same time at Local time when sun comes over head –(NO
shadow on East or West) the calculations will be simplified as follows. Anti tan
1/3000 gives the angle made by shadow on the Earth surface gives the angle = at
the centre of the Earth by the distance of the place “A”to “B” on the surface of
the EARTH. Eg about 1.145’ (1+’) and find the Circumference of the Earth = 360
degree. (around 40000 Km)

Similarly Controlled reading at “N” / “S” will help you to find accuracy eg long
distance measure will give more accuracy than 2KM and correct your readings from
that 50 KM distance experiments. (that will give you about 23.5 mm shadow
Difference than that of “A” and 23.5+1 mm than that of “B”) so calculate the
anti tangent and angle and circumference of the Earth and Diameter or R for the
Earth.

TO SIMPLIFY MORE and Easy work, Let One of the 'N' OR 'S' be Either Delhi Jantar
Mantar or JAIPUR - JANTAR MANTAR.

We are very rich in our Astronomy engineering - particularly JAIPUR is the
Richest in that sense. Jaipur has very good working observatory (VEDH SHALA)
with guiding facility.

According to an expert guide (who are also expert in astronomical calculations)-
And that all works local timing and longitude - latitude of the place. Only the
persons required to work for it.

We should utilize that place with aided observation with Summer solstice of 21
June 2009 . TEAM A - working with Local observatory guides and Team B working
with at the 23.5 N. That is the best place for us to utilize the observation at
that place and that is relay an opportunity for Jaipur & Delhi and users too.
