Dear Science, Maths, History and astronomy Friends, Subject: HAPPY EQUINOX day, longitude latitude measurement methods by Angle meaurement of the sun - 20 March/22 sept 2009 LONG LATI @RAMKUND Happy EQUINOX day, longitude latitude measurement methods by Angle meaurement of the sun - LONG LATI @RAMKUND From: kutchsciencefoundation@... Subject: HAPPY EQUINOX day, measurement of the sun - 20 March/22 sept 2009, methods of Angle of sun and LONGITUDE LATITUDE @RAMKUND of BHUJ. UTC date and time of solstices and equinoxes[1] year Equinox Mar Solstice June Equinox Sept Solstice Dec day time day time day time day time 2009 20 11:44 21 05:45 22 21:18 21 17:47 Wish you all a very happy March EQUINOX day 20 March/22 sept 2009 On the Equinox day and all measurement activity is done in the equinox day time at RAMKUND of BHUJ. As Ramkund is perfectly constructed according to the Sun dial principles. E-W N-S. and all constructions are perfect rectagular and perpendicular. for measurement one do not need to manage any such directions and leveling But only Shadow measurenets ONLY for sun dialing as we do in JANTAR MANTAR of Delhi or JAIPUR. And that also will give the idea when tropic of cancer was passing there at RAMKUND at that time many centuries ago. (23 14 51 N). Example of Latitudes longitude finding at the Local time. – for tropical of cancer @ Local time you need to find the correct time when sun is on 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. for Bhuj 12:52 PM http://groups.yahoo.com/group/scienceclubindia/files/MeasureEarth.doc http://f1.grp.yahoofs.com/v1/AMoxQMYX-9fiVHuxQHOo41ARbHhUCCePM4vTyesgNwoaLECS-Pj\ S97i5cgQxpGVZJxToBmG788WFGK948sho/MeasureEarth.doc Hints: as Calculation of Latitude Longitude of the Place on Earth (eg RAMKUND) we need to measure the angle of Sun. As on the Equinox day The sun is on the the Equater, we need to go to the place on befor 12PM IST. At 12 PM IST see the Northern steps Shadow showing towards the West will be seen. on the day. wait for the local time 12:00 NOON which will be at 12:52 PM IST. Measuring the Angle of the SUN : Similar Example of Latitudes longitude finding at the Local time. – for tropical of cancer @ Local time you need to find the correct time when 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. As at 12 PM IST shadow on the RAMKUND will be towords the west of NORTHERN STEPS of the RAMKUND. See when The shadow becomes perpedicular as line drawn in steps diagrams, Shadow will be perfectly downwards in the plum line. If Above picturenot seen here ara attached with the email 1) Angle Measurement@... 2) RAMKUND STEPS Shadow.jpg Now you find exact time when to there is shadow in exactly perpendicular line. That say time is 12:52 than time difference is 52 minutes which is 52/4=13 dehrees means BHUJ is at 82.5-13=69.5 East. LONGITUDE MEASUREMENT. At this time you need to measure the lenth of the shadow at south steps as shown in other diadram. and measuer the angle of the sun . which is equal to the Latitude of the place as the sun is on Equater. LATITUDE MEASUREMENT. as ramkund is constructed perfectly E W NS ans in perfect square and perpendicular as reverse of PYRAMIS in the ground and exactly according to rules Like pyramids accuracy. Lenth of Shadow/height will give Tangent of the angle . tanke an anti tangent of the figure you get by Shadow/height . thats the angle of the tilt of sun. Thats the Latitude of the place RAMKUND. As you are @ RAMKUND check how accurate is your experiment with figures of RAMKUND (23 14 51 N).
