New Delhi, May 27: As per the prediction from the IMD, severe heatwave conditions continued in several parts of north India with Delhi recording the country’s second-highest temperature at 47.6 degrees Celsius. On the other hand, Churu in Rajasthan sizzled at 50 degrees Celsius, reporting the highest temperature in the country.

In Delhi, the mercury soared to 47.6 degrees Celsius in Palam area and most places recorded their maximum temperatures six notches above normal. The Safdarjung Observatory, which provides representative figures for the city, recorded a maximum of 46 degrees Celsius.

The last time when the mercury at the Safdarjung weather station touched the 46-degrees-Celsius mark was on May 19, 2002.

The IMD said the weather stations at Lodhi Road and Aya Nagar recorded their respective maximum at 45.4 degrees and 46.8 degrees Celsius.

In its earlier forecast, the IMD has said that dust storm and thunderstorm with winds gusting up to 60 kilometres per hour is likely over the National Capital Region on Friday and Saturday.

On the other hand, severe heatwave conditions prevailed in several parts of Rajasthan on Tuesday, with the mercury touching 50 degrees Celsius in Churu district.

The IMD said this is the second-highest maximum temperature recorded in Churu district in the month of May in the last 10 years.

Other areas such as Bikaner, Gangangar, Kota and Jaipur recorded maximum temperatures of 47.4 degrees Celsius, 47 degrees Celsius, 46.5 degrees Celsius and 45 degrees Celsius, respectively.

In the adjoining areas of Chandigarh, the severe heatwave condition continued in Haryana, Punjab with Hisar being the hottest place in the region at 48 degrees Celsius.

New Delhi, Jun 20: A rare celestial event, annular solar eclipse, which is popularly known as the "ring of fire" eclipse, will be visible this Sunday in India.

It will be the first solar eclipse of this year takes place on the summer solstice, which is the longest day in the Northern Hemisphere.

While people living along the path annular eclipse passing through Anupgarh, Suratgarh, Sirsa, Jakhal, Kurukshetra, Yamunanagar, Dehradun, Tapowan and Joshimath will be able to see the annular phase, people in rest of India can witness a partial eclipse, said the Ministry of Science and Technology.

When Moon comes between the Sun and Earth, the shadow falls on the surface of the Earth. The Sun is entirely covered by the Moon for a brief period. Those places that are engulfed by the dark, dense umbral shadow of the Moon experience the total solar eclipse. In the regions that plunge into the soft diffused penumbral shadow of the Moon experience the partial eclipse.

"Annular solar eclipse is a particular case of the total solar eclipse. Like the total solar eclipse, the Moon is aligned with the Sun. However, on that day, the apparent size of the Moon happens to be a wee smaller than the Sun. Hence the Moon covers the central part of the Sun, and the rim of the Sun appear like a 'ring of fire' in the sky for a very brief moment" explains Samir Dhurde of The Inter-University Centre for Astronomy and Astrophysics, Pune.

During the solar eclipse, the apparent size of the Moon is smaller than that of the Sun by 1 per cent, the expert said.

Allying rumours that the eclipse will mark the end of coronavirus, Aniket Sule, Chairperson, Public Outreach and Education Committee of the Astronomical Society of India, said: "Solar eclipse is caused when the Moon comes in front of the Sun for a short time. As seen from Earth eclipses occur somewhere in the Earth 2 to 5 times a year. Eclipses do not impact microorganisms on Earth. Likewise there no danger in eating of stepping out during an eclipse. No mysterious rays come out of the Sun during an eclipse."

Jan 17: India's "high power" communication satellite GSAT-30 was successfully launched in the early hours of January 17, the Indian Space Research Organisation (ISRO) said.

The satellite, aimed at providing high-quality television, telecommunications and broadcasting services, was launched onboard Ariane 5 rocket from French Guiana.

Blasting off from the Ariane Launch Complex in Kourou, a French territory located in northeastern coast of South America at 2.35 am IST, European space consortium Arianespace's Ariane 5 vehicle injected GSAT-30 into the orbit in a flawless flight lasting about 38 minutes.

Arianespace CEO Stéphane Israël tweeted about the successful launch of GSAT-30.

ISRO's U R Rao Satellite Centre Director P Kunhikrishnan, who was present in Kourou, congratulated the ISRO community and Arianespace team on the successful launch.

Calling it an "excellent start" to 2020 for ISRO with the launch, he said, "The mission team at the master control facility have already acquired the satellite and they will immediately complete the post launch operations...."

The 3,357-kg satellite, which was deployed from the lower passenger position of Ariane-5 launch vehicle (VA 251) into to geostationary transfer orbit (GTO), is configured on ISRO's enhanced I-3K Bus structure to provide communication services from Geostationary orbit in C and Ku bands.

The satellite derives its heritage from ISRO's earlier INSAT/GSAT satellite series, and is equipped with 12 C and 12 Ku band transponders.

GSAT-30 is to serve as replacement to the "aging" INSAT-4A spacecraft services with enhanced coverage, ISRO has said, adding the satellite provides Indian mainland and islands coverage in Ku-band and extended coverage in C-band covering Gulf countries, a large number of Asian countries and Australia.

With a mission life of 15 years, GSAT-30 is an operational communication satellite for DTH, television uplink and VSAT services.

The Bengaluru-headquartered ISRO has said the communication payload of GSAT-30 is specifically designed and optimised to maximise the number of transponders on the spacecraft bus.

According to the space agency, the spacecraft would be extensively used for supporting VSAT (Very Small Aperture Terminal) network, television uplinking and teleport services, digital satellite news gathering (DSNG), DTH television services, cellular backhaul connectivity and many such applications.

One Ku-band beacon downlink signal is transmitted for ground-tracking purpose, it added.

For its initial flight of 2020, Arianespace on its website said, it would orbit EUTELSAT KONNECT, a telecommunication satellite for the operator Eutelsat, along with GSAT-30, using an Ariane 5 launch vehicle from the Guiana Space Centre.

EUTELSAT KONNECT – which was produced by Thales Alenia Space for Eutelsat – was riding in the upper position of Ariane 5's payload arrangement, and was released first in the flight sequence at 27 minutes following liftoff.

Since the launch of India's APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 24 satellites, including GSAT-30, for the Indian space agency.
