What is Cyclone Sagar?

Indian Met Department has issued an alert to Tamil Nadu, Kerala, Karnataka, Goa, Maharasthra and the Lakshadweep over the cyclone ‘Sagar’, which is building up over the Arabian Sea with potential to hit the coastal region of northern Indian Ocean on Saturday.

Formerly known as 01A, Tropical Cyclone Sagar, quickly formed in the Indian Ocean and strengthened into a tropical storm on May 16 at 3:35 a.m. IST as shown in the resolution imaging captured by the spectroradiometer aboard NASA’s Aqua satellite.

It showed thunderstorms at minus 80 degrees Celsius, which means very strong storms with a potential for heavy rainfall in the Arabian Sea with maximum sustained winds near 46 miles per hour (40 knots). Located near 13.0 degrees north latitude and 48.6 degrees east longitude, or approximately 229 nautical miles east of Aden, Yemen.

When captured NASA-NOAA’s Suomi NPP satellite appeared more organized and has been strengthening since May 17. On Friday, May 18 the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite captured a true-color image of Tropical Cyclone Sagar showing the center above the Gulf of Aden, affecting Yemen and Somalia.

At 1:30 p.m IST, the Tropical Cyclone Sagar was centered near 11.6 degrees north latitude and 45.9 degrees east longitude, approximately 89 nautical miles southeast of Aden, Yemen, registering maximum sustained winds up at 69 mph (50 knots/111 kph). Currently, Sagar is moving to the west-southwest at 6.9 mph (6 knots/11.1 kph).

Sagar is likely to threaten Yemen, Somalia and Djibouti with waves as high as 17 feet, before hitting the Indian west coast on Saturday. The Indian Meteorological Department (IMD) has issued an advisory that said: “Strong winds reaching upto 75-85 kmph and 95 kmph covering the Gulf of Aden and adjoining south-western Arabian Sea area are very likely duting the next 12 hours. It may then gradually decrease ato 65-75 kmph during the next 12 hours.”

Fishermen are advised not to venture into the high seas of the Gulf of Aden or west-central and south-west Arabian Sea in the next 48 hours.

Sunday May 6: Solar Storm to cause Mobile, TV, Tech Blackout on Earth?

US space agency NASA has informed that a solar storm brewing on Sun is flaring up splitting huge sun storms which may reach earth on Sunday, May 6. It said a coronal hole or sun spot has opened up releasing huge swarm of cosmic rays which may take 8 minutes to reach earth.

The space weather watching unit of National Oceanic and Atmospheric Administration (NOAA) said the solar tsunami can create an aurora or polar lights when it hits earth. Astronomers have estimated that three such solar storms are likely to reach earth on May 6, to be precise, the Indian Ocean and India is very much within the target area.

The storm classified as G-1 or ‘minor’ is the biggest since 2004 and it could trigger sparks and melt soil on Moon, while its impact on Earth is still not comprehended by astronomers but similar storms had apparently given birth to origin of life on earth.

A section of scientists warned that the solar storms on Sunday could be severe enough to disrupt communications, satellite-based GPS, flaring up magnetic field around electricity power stations or transmitters. A partial tech blackout is likely to disrupt the Internet-based communications, they added.

Effects on Earth?

Since the severity has been classified as low by NOAA, it may cause voltage fluctuations in electricity supply or even cause power failures for now. However, the US Space Weather Prediction Center (SWPC) has issued a storm alert on Sunday and Monday stating that the solar storm could cause a “high stream of activity” that is characteristic to any G1-class storm. The gigantic coronal hole in the sun’s surface was captured today by NASA’s Solar Dynamics Observatory (SDO), said SWPC.

G1 (Minor) geomagnetic storm watches have been issued for 06 and 07 May 2018 due to the anticipated effects of a negative polarity coronal hole high speed stream… Aurora may be visible at high latitudes, that is, northern tier of the US such as northern Michigan and Maine,” said SWPC in a statement.

Meanwhile, conspiracy theorists woke up to the situation to claim that these disruptions are due to the effect of an approaching Nibiru planet which is lurking in the vicinity of our solar system. David Meade, its proponent, has repeated that the next seven years will witness tribulation with many more calamities. NASA has denied these claims as Internet Hoax, though.

50-Year-Cycle?

 

Researchers have long announced that a storm is likely to come and the most intense solar flare may reach earth in maximum fifty years. It is not sure whether the Sunday storm was the one or not.

Mausumi Dikpati of the National Center for Atmospheric Research (NCAR), who’s been working on these storms for decades, predicted that the next solar storm will be a stronger one. “The next sunspot cycle will be 30% to 50% stronger than the previous one,” she said a few years ago. It can produce a burst of solar activity second only to the historic Solar Max of 1958.

Earlier, such intense solar storms had been observed in 1805 and 1958 but with no mobiles and magnetic power lines, the disruption was not detectable as clearly as it would today when auroras and cell technology will showcase the real impact.

According to solar physicist David Hathaway of the National Space Science and Technology Center (NSSTC), a typical sunspot exists for just a few weeks. When it decays, it leaves behind a ‘corpse’ of weak magnetic fields.

Whether the big Doomsday is Sunday or not will be known sooner. For now, a storm is coming and how big will it be remains a major question.
