Mission: Observation of TSE 2009
from a height of 25000 ft
Vigyan Prasar and Indian Air Force jointly coordinated and executed a scientific campaign
during the total solar eclipse on 22 July 2009 to record the eclipse. One transport aircraft AN32 and two fighter aircraft Mirage 2000 participated in two different missions.

the aircraft primarily to observe solar corona at different
wavelengths. Wg Cdr D. Singh was the captain while Flt
lieutenant Palekar was the co-pilot. Wg Cdr Arvind Sharma was
the navigator of the mission.
Dr. Kamble and Professor Venkatakrishnan chalked out detail
flight plan in consultation with the captain and navigator. It was
decided that the aircraft would fly from Agra to Gwalior and
proceed towards Khajuraho and then enter in the belt of totality
and fly along the central line but in a direction opposite to the
direction of movement of the umbral shadow, i.e., towards west. It
was decided that elevation of the Sun should be at 10 degrees from

ground to enable proper view while capturing the event from a
height of 25,000 feet (7,600 m).
A medical checkup was conducted on 20 July 2009 for all
the crew members and others who would go on the flight. Everyone
was given detailed instructions on flight safety and emergency
procedures. They were also given training on handling oxygen
cylinder and the mask
On 21 July 2009, there was a practice flight on board AN32 aircraft to finalise the path and to carry out minor corrections.
However, during the flight, thick cloud cover was observed even
at a height of 25,000 feet and Sun was visible only for a short
duration. After a three-and-half-hour flight, the team returned
to Agra Air Force base station. Corrections for the scheduled
flight path on 22 July were made based on the weather report.
On 22 July 2009, all the members were ready by 0330 hrs.
Mission briefing was held at by 0335 hrs. The aircraft took off at
0430 hrs. After reaching the belt of totality at Murwara at around
0535 hrs, the aircraft flew towards east for about 35 km. Then it
flew in a path similar to race course track with longer side about
10 km and shorter side 3 km, the ‘hold’ area. After three such loops
at holding point, the aircraft turned towards west at a height
25,000 feet with its ramp open at 0614 hrs. Scientists from
Udaipur Solar Observatory, Vigyan Prasar and the team from
Doordarshan were positioned at the tail side of the aircraft and
watching the Sun in its partial eclipse phase.

Scientists from Udaipur Solar Observatory took observations
of the eclipse through telescope and conducted the experiments.
Scientists from Vigyan Prasar and members of Doordarshan team
recorded the event and took photographs. Totality started at 0621
hrs and continued till 0624 hrs. During this phase the
chromosphere, diamond ring and corona were observed. After
totality the sequence of events went on in the reverse order.
VIPNET Questionnaire 162
The ramp was closed at 0628 hrs. The aircraft returned to
Agra base at 0745 hrs. The event drew good media attention.
Several television channels were present at Air Force station on
conclusion of the mission and interviewed Dr. V. B. Kamble,
Professor Venkatakrishnan and the officials of Indian Air Force.
Video feed of the eclipse was given to media.

Mission II: Observations from the Mirage 2000
Professor K. E. Rangarajan of Indian Institute of Astrophysics,
Bangalore coordinated the mission on board Mirage 2000 to
observe and photograph the solar corona up to a distance of 12 –
13 solar radii with a digital SLR camera using zoom/ wide-angle
lens. In view of the fact that there would be no gain in chasing the
umbral shadow due to its very high speed, a decision was taken to
fly the aircraft at an angle from north to south. A trial flight was
arranged on the morning of 21 July 2009. The pilot flew the aircraft
while the co-pilot took the picture. On 22 July 2009, two Mirage
2000 participated in the mission flown by Group Captain Samyal
and Air Commander Neelakantan. Both the aircraft were
successful in capturing very good photographs of the corona.

VIPNET Photo Quiz - 41, VIGYAN PRASAR, A-50, Sec.
62, Noida
Correct Answer of Photo Quiz 39
Horsehead Nebula
The Horsehead Nebula is a dark nebula in the constellation Orion.
The nebula is located just below Alnitak, the star furthest left on
Orion’s Belt, and is part of the much larger Orion Molecular Cloud
Complex. It is approximately 1500 light years from Earth. It is one
of the most identifiable nebulae because of the shape of its swirling
cloud of dark dust and gases, which is similar to that of a horse’s
head.

I
ndia witnessed the longest Total Solar Eclipse (TSE) of this
century on 22 July 2009. Total Solar Eclipse was visible from
many cities of India, like Surat, Vadodara, Indore, Bhopal, Jabalpur,
Allahabad, Varanasi, Patna, Darjeeling, Dibrugarh etc. The central
line of the Moon’s shadow started at 06:21 IST from India’s western
coast. The Total Solar Eclipse began at early morning; in fact, most
of the cities saw the rising sun as an eclipsed Sun. The longest
totality visible from land mass area in ocean was about 06 minutes
34 seconds, which lied in remote island of Japan named Kitaio
Jima. The maximum duration of totality was 6 min 39 seconds
when the Sun’s altitude was about 86° and the path width was
around 258 km.
As part of programme
VP
successfully
completed a countrywide
campaign on Total Solar
Eclipse (TSE)-2009
creating awareness among
the students, teachers and

the campaign with the school students of Delhi and NCR region
since February 2009. During February to June 2009, VP organized
seven awareness programmes in various government schools with
the cooperation of Directorate of Education, Government of Delhi
and in some of the public schools like Amity group of schools, chain
of Bal Bharati Public Schools etc. There were around 250 teachers
and more than 500 students from government schools of Delhi and
public schools who were trained for safe observation of TSE.
During the programme, presentation on eclipses with emphasis
to TSE 2009 was given. The Astronomy kit developed by VP was
demonstrated along with the projection methods for observing TSE
safely. The participants were also introduced to the activities of
Vigyan Prasar and about International Year of Astronomy 2009.
This was followed by a series of awareness programmes,

programme was inaugurated by Shri Muktesh Singh, President
of Children’s Science Centre and Chairman of Emerald Heights
International School, Indore. During the session a lecture on
TSE along with demonstration of Astronomy kit, projections
methods for observing TSE was delivered by the scientists of
Vigyan Prasar and Shri Saikat Chanda and Shri Rajendra Singh

including VIPNET club members, students of Emerald Heights
school, teachers and other local schools and general public.
On the day of the eclipse (22nd July, 2009), the excitement
of all the participants assembled early in the morning was
dampened due to rain and cloudy weather. Though the weather
was bad and rain disturbed the viewing of the eclipse. But all
the participants experienced the sudden brief darkness during
the time of totality (6.21am to 6.24 am) and the behaviour of
birds and other animals. The students enjoyed this unique
experience of sudden
darkness for 3
minutes 15 seconds.
There was wide
media coverage of
the event both in
print and electronic
media. In the
afternoon, one of the

At Bhopal, Madhya Pradesh
A national camp was organized for observing the Total Solar
Eclipse from the belt of totality at Bhopal in the foot-hills of
Bhim Betika from 21-23 July 2009. The programme was jointly
organized by NCSTC, DST, Vigyan Prasar and Science Centre,
Bhopal. The three day camp was attended by the 110 VIPNET
clubs (325 club members) from twenty States of the country.
These clubs were selected for joining the camp on the basis of
the project reports submitted on “myths and superstitions
prevalent in their area relating to Eclipse and other Celestial
bodies.” For each report, two children and coordinator were
invited to attend the three day camp.
During the camp, a series of activities like demonstration
of kits, quiz on astronomy, interaction with scientists, film

shows, sky observations etc. were organized. Prof. Yash Pal was
present as one of the key speakers. Interaction with him was a
very enjoyable experience for all children. Shri Biman Basu
(Former Editor, Science Reporter) was one of the other key
speaker. During his lecture, he equipped the children on safe
viewing of the eclipse beside briefing them about the causes
and types of Eclipse. Selected children specially the winners

programme. During the programme, the
lectures, presentation and demonstration
of Astronomy kits etc. were delivered by
the resource persons. On the day of the eclipse, the participants
were gathered at the Gandhi Maidan, Patna for observing the TSE.
Though the participants could not see the initial sequence of the
eclipse before totality due to sudden rain but they could witness the
eclipse after the totality. Here, again the students were equally
excited to see the night like darkness at the time of totality, a life
time experience for all of them. The programme was attended by
more than 300 students and teachers.
As a part of this programme, a telescope assembling
workshop was also organized at Bhopal from 18-21 July 2009
jointly with Science Centre Gwalior. This was the second
workshop of the series, in which 60 teachers representing
VIPNET Clubs from different schools had participated. These
teachers were also trained during the workshop to work as
volunteers for the camp for observing the TSE on July 22, 2009.
In this workshop about 60 Gallelien telescopes were assembled
and participants were given the telescope to be used during the
eclipse to project the image of Sun in eclipse stage to start
astronomical activities in their clubs.
Astronomy Kits with Solar Filter developed by Vigyan Prasar
were earlier distributed to the participants on July 21, 2009 preceded
