May 4, 2016

Kolkata, May 4: A transit of Mercury over the disc of the sun will take place in the afternoon of May 9 and will be visible from India after a gap of about ten years.

The transit of Mercury is a phenomenon in which the planet will be seen as a small black dot travelling from one end of the solar disc to the other, according to Sanjib Sen, Director, Positional Astronomy Centre.

This phenomenon is seen when mercury passes between the sun and the earth and it happens only when the three are lined up, Sen said.

Mercury appears as a dot on the solar disc because its angular size is very small compared to that of the sun as seen from earth.

Sen said the transit of mercury will be visible from most of Asia (except south eastern parts and Japan), Europe, Africa, Greenland, South America, North America, Arctic, North Atlantic Ocean and most of the Pacific Ocean.

The transit will be visible in India after ten years and the next it will be visible in the country after a long gap of 16 years in 2032, he said.

The transit of Mercury begins with contact-I, the instant when the disc of Mercury is externally tangent with the sun (ingress exterior) followed by contact-II, when Mercury is internally tangent with the Sun (ingress interior).

Mercury will be seen as a black spot, travelling several hours over the face of the disc and will reach the opposite limb of the sun at contact-III, when the disc of Mercury is internally tangent with the sun (Egress interior).

Finally the transit ends at contact-IV when the disc of Mercury is externally tangent with the sun (egress exterior).

The transit of Mercury is relatively a rare phenomenon, occurs 13 or 14 times in a century, mostly in the months of May and November.

The interval between one November transit and next November transit may be seven, 13 or 33 years, whereas the interval between a May transit and the next May transit may be 13 or 33 years.

The beginning of the event - Ingress exterior (contact-I) and Ingress interior (contact-II) will be visible from all places in India, Sen said.

The duration of the entire transit event will be about 7.30 hours. The observers in India will not see the ending of the event as the same will be in progress after sunset.

Depending upon the sunset time of different places in India, the observer located at the extreme east of the country will witness the event for an hour from the beginning and the observer located at the extreme west in the country will see the event for about 2.40 hours from the beginning, he said.

In Delhi, the event can be seen for a duration of about 2.20 hours as it will start at 4.41 PM and sunset will take place at 7.01 PM.

Similarly, in Kolkata the event will start at 4.41 PM and can be seen for a duration of about 1.26 hours.

In Mumbai, the event will start at 4.41 PM and can be seen for a duration of about 2.24 hours and in Chennai the event will start at 4.41 PM and it can be seen for a duration of about 1.45 hours, Sen said.

The last transit of Mercury occurred on November 6, 2006, when the end of the event was visible from the extreme north eastern parts of India at the time of sunrise.

The next transit of Mercury will take place on 11 November, 2019 but the event will not be seen from India as it will begin after the time of sunset in India. The transit of Mercury on 13 November, 2032 will be again visible from India.

The apparent diameter of Mercury will be nearly 12 arc-second which is 1/158 of Sun's apparent diameter. Thus, it will be difficult to see the Mercury at transit over the face of the sun without optical magnification.

This event can be viewed with the help of binoculars or telescope attached with proper solar filter or by making projection of the sun's image on a white board by telescope.
The sun should never be seen with the naked eye, cautioned Sen.

The safe technique to observe is by using filter-like aluminised mylar, black polymer or welding glass of shade number 14.

The Positional Astronomy Centre is planning to show the event to general public from its office at Sector-5 in Salt Lake on May 9.

Several women, believed to be victims of Prajwal Revanna, have left their homes in Karnataka's Hassan district over the last ten days, according to media reports.

These departures reportedly come amid fear and stigma after their identities became public due to the circulating video clips showing the women who were allegedly sexually assaulted by Prajwal Revanna.

"The entire district is in H D Revanna’s control. You speak ill about them and chances are high that it will reach them, because the family and the party have a large following," a shopkeeper in Hagare - 20 km from Hassan – was quoted as saying by the news paper. 

Hassan is the bastion of the JD(S) supremo Deve Gowda, and Prajwal, his grandson, is the sitting MP.

The family of the woman whose complaint was the basis of the first FIR against Prajwal has now left their home, the publication reported, citing a neighbour who said, "The woman worked at Revanna’s house as a house help. Some of her videos started to circulate and then, her house was seen locked. We don’t know when she left."

Notably, a former Zilla Panchayat member has also filed a rape case against Prajwal, and in that village many women who worked for the party formerly are now incommunicado, a JD(S) leader told the publication. "We noticed many of the party women deleting their photos with Prajwal on social media. In some instances, men are questioning their wives about their association with the MP. It is shattering the lives of many women in the district," he said.

The local leader added that the former Zilla Panchayat member was there on April 24, but no one had seen the family since the videos came out.

The case is currently being probed by an SIT team and when they reached the Revanna residence, party workers were reportedly heard talking about the women. "I know this woman, she lived close to our residence and was very active in JD(S) activities. Her house is locked… she has small children," one said, as per IE.

Another shopkeeper added, "It was really wrong to reveal the faces of the women. I know some of them, and they have gone into hiding. We don’t know whether they can return."

He noted that it is impossible to survive in Hassan while fighting a case against the Revanna family.

While Prajwal's father, H D Revanna is in SIT custody, a Blue Corner notice has been issued against the sitting MP.

Hubballi, May 17: Karnataka Police have arrested the killer, Vishwa, also known as Girish, in the sensational Anjali Ambigera murder case, police said on Friday.

Preliminary investigations reveal that Vishwa was a habitual thief who exploited innocent young women. The accused is also a drunkard and was caught while attempting to commit theft. He was also part of a gang which stole bikes.

The accused targeted gullible young women, enacting a drama of love and playing the emotional card to forcefully extort gold, silver, and cash from them. When Anjali did not agree to any of his attempts to rob her and outrightly rejected his offer to go with him to Mysuru city, he brutally killed her.

The police had formed two teams to hunt down the killer. One of the teams was searching in the south Karnataka region, and another team, which launched a hunt in Davanagere, nabbed him. The accused was arrested by the police on Thursday.

The police could not catch him sooner as the killer did not carry a mobile phone and did not use his phone for 15 days, before murdering Anjali. The jurisdictional Bendigeri Police were aware of the killer's history, but even after the complaint by the girl’s family, they showed "utter negligence".

The 24-year-old Vishwa entered Anjali Ambigera's (20) residence at 5.30 A.M. on Wednesday and stabbed the young woman multiple times before she could react. Vishwa dragged Anjali Ambigera all over the house, kicking and stabbing her. Later, he pushed her into the kitchen where he stabbed her repeatedly.

Despite efforts by Anjali’s grandmother and two sisters to stop the attacker, he killed her and managed to flee. The incident occurred in the Veerapura Oni area within the jurisdiction of the Bendigeri Police Station.

Vishwa had been blackmailing Anjali and pressurising her to accompany him to Mysuru without informing her parents. The incident which took place close on the heels of MCA student Neha Hiremath’s brutal murder by the jilted lover has raised concern over the safety of women all across the state.

The BJP had demanded the resignation of Home Minister G. Parameshwara while the Congress leaders have also demanded that the Hubballi-Dharwad Police Commissioner Renuka Sukumar should be transferred for failing to sensitise the police force regarding issues of women’s safety.

rafah.jpg

Israeli military aircraft have heavily bombed the city of Rafah in the southern Gaza Strip accompanied with ground advances shortly after the Palestinian resistance movement Hamas said it had agreed to a proposal on ceasefire in Gaza.

A Palestinian journalist reported flares in the night sky, while locals said dozens of reconnaissance drones flew overhead.

The official Palestinian news agency Wafa and Egyptian media said Israeli military vehicles advanced towards the Palestinian side of the Rafah crossing with Egypt, as well as the Karem Shalom crossing with the Israeli-occupied territories.

A Palestinian security official and an Egyptian authority have told the Associated Press news agency that Israeli tanks have entered Rafah, reaching as close as 200 meters from Rafah’s border crossing with neighboring Egypt.

The Israeli military has said it was conducting “targeted strikes” against Hamas in eastern Rafah.

Israeli prime minister Benjamin Netanyahu's office has also said "Israel is continuing the operation in Rafah to exert military pressure on Hamas" in order to advance the release of captives and what it called "the other objectives of the war."

In the meantime, it described the proposal on ceasefire as "far from Israel's essential demands," but added that it would send negotiators for talks "to exhaust the potential for arriving at an agreement."

The military strikes on Rafah came ahead of talks in Egypt on Tuesday aimed at sealing a truce proposal accepted by Hamas, which was put forward by Qatari and Egyptian mediators. 

According to a copy of the proposal, there will be three phases to ending Israel’s onslaught against Gaza.

The first phase calls for a complete withdrawal of Israeli troops from the Netzarim corridor and the return of displaced Palestinians to their homes. The second phase involves an announcement of a permanent cessation of military operations. In the last phase, there would be a complete end to the blockade of the Gaza Strip. 

In return, Israel would be required to release an unspecified number of Palestinian prisoners, withdraw its troops from certain regions of the Gaza Strip, and allow Palestinians to travel from the south of the coastal sliver to the north.

About 1.5 million Palestinians are sheltering in Rafah, once designated a “safe zone” by the Israeli military. Palestinians are now struggling to evacuate the city, after the Israeli military dropped leaflets ordering them to leave as a large-scale assault on the city is planned.

UN Secretary General Antonio Guterres has said that a ground invasion of Rafah would be “intolerable” and called on Israel and Hamas “to go an extra mile” to reach a truce deal.

“This is an opportunity that cannot be missed, and a ground invasion in Rafah would be intolerable because of its devastating humanitarian consequences, and because of its destabilizing impact in the region,” Guterres told reporters on Monday ahead of a meeting with Italian President Sergio Mattarella in New York.

Jordanian Foreign Minister Ayman Safadi has also warned that Israel is “jeopardizing the deal by bombing Rafah.”
