Dear Science and Astronomy friends,
Congratulations dosto.:
MEGHPAR - Gadhwaliwadi 23.30N - 69.03E Narapa 23.34N - 69.05E Vada
23.34N - 69.03E

As you must be aware of timing, Should you have taken in mind to take reading
round 12:51 and 12:52 for Bhuj and Naranpar Meghpar. Still Mean time of reading
12 and 14 can be placed as follows from selected below table.
13) 12:46:51 PM 21.8 cm

13a) - 12:49:58 pm mean time 21.3 cm mean size shadow

Mean time : of reading 12 and 14 can be calculated as : (12:56:04Pm) - (12:43:51
PM) /2 = (0:12:13)/2 = 6m:07sec added to result 12 time = 12:43:51 PM + 6m:07sec
= 12:49:58 PM

Similarly : Mean shadow length : of reading 11 to 14 can be calculated as :
12 & 13 as 0.5cm reduction @ 3 min interval: so expected at 12:49:51 21.8 -0.5 =
21.3 cm
and then reverse increase of 0.5 cm at 3 minute interval @ 12:52:51 back to 21.8
cm
and back to result 14 after another 3 minute interval @ 12:56:04 =22.3 cm.
But errors needs to be corrected. any way good attempt. best luck to correct
errors on next day for verification of results to remove errors.

Length of poll :-55.5cm
No: Time Length of Shadow
11) 12:40:06 PM 22.6 cm
12) 12:43:51 PM 22.3 cm
13) 12:46:51 PM 21.8 cm
14) 12:56:04 PM 22.3 cm
