Ionospheric convection response to slow, strong variations in a northward interplanetary magnetic field: A case study for January 14, 1988

first_imgWe analyze ionospheric convection patterns over the polar regions during the passage of an interplanetary magnetic cloud on January 14, 1988, when the interplanetary magnetic field (IMF) rotated slowly in direction and had a large amplitude. Using the assimilative mapping of ionospheric electrodynamics (AMIE) procedure, we combine simultaneous observations of ionospheric drifts and magnetic perturbations from many different instruments into consistent patterns of high-latitude electrodynamics, focusing on the period of northward IMF. By combining satellite data with ground-based observations, we have generated one of the most comprehensive data sets yet assembled and used it to produce convection maps for both hemispheres. We present evidence that a lobe convection cell was embedded within normal merging convection during a period when the IMF By and Bz components were large and positive. As the IMF became predominantly northward, a strong reversed convection pattern (afternoon-to-morning potential drop of around 100 kV) appeared in the southern (summer) polar cap, while convection in the northern (winter) hemisphere became weak and disordered with a dawn-to-dusk potential drop of the order of 30 kV. These patterns persisted for about 3 hours, until the IMF rotated significantly toward the west. We interpret this behavior in terms of a recently proposed merging model for northward IMF under solstice conditions, for which lobe field lines from the hemisphere tilted toward the Sun (summer hemisphere) drape over the dayside magnetosphere, producing reverse convection in the summer hemisphere and impeding direct contact between the solar wind and field lines connected to the winter polar cap. The positive IMF Bx component present at this time could have contributed to the observed hemispheric asymmetry. Reverse convection in the summer hemisphere broke down rapidly after the ratio |By/Bz| exceeded unity, while convection in the winter hemisphere strengthened. A dominant dawn-to-dusk potential drop was established in both hemispheres when the magnitude of By exceeded that of Bz, with potential drops of the order of 100 kV, even while Bz remained northward. The later transition to southward Bz produced a gradual intensification of the convection, but a greater qualitative change occurred at the transition through |By/Bz| = 1 than at the transition through Bz = 0. The various convection patterns we derive under northward IMF conditions illustrate all possibilities previously discussed in the literature: nearly single-cell and multicell, distorted and symmetric, ordered and unordered, and sunward and antisunward.last_img read more

Neptune Energy drills dry well near Heidrun field in Norwegian Sea

first_imgThe well was aimed to determine the presence of petroleum in Lower Jurassic reservoir rocks The wildcat well was terminated in the Åre Formation in the Lower Jurassic. (Credit: Pixabay/D Thory) Neptune Energy Norge and its partners have concluded the drilling of wildcat well 6507/8-10 S in the production licence 889 in the Norwegian Sea.Drilled about 10km east of the Heidrun field and 215km west of Brønnøysund, the well was aimed to prove the presence of petroleum in Lower Jurassic reservoir rocks (the Tilje and Åre Formations).The wildcat well has been drilled to a measured depth of 2,399m and a vertical depth of 2,311m, using West Phoenix drilling facility.Following drilling, the well encountered the Tilje Formation with a thickness of about 150m. The sandstones totalled about 100m with good to very good reservoir quality.Norwegian Petroleum Directorate (NPD) said that the Åre Formation at the well encountered a thickness of about 195m, with sandstone layers totalling around 100m with good to very good reservoir quality.Wildcat well 6507/8-10 S to be permanently plugged and abandonedSince the petroleum traces were not proven, the Well 6507/8-10 S has been declared dry. The well, which was terminated in the Åre Formation in the Lower Jurassic, is planned to be permanently plugged and abandoned.The production licence 889 is operated by Neptune Energy Norge with 50% stake while other partners include Wellesley Petroleum (20%), Equinor Energy (20%), and Sval Energi (10%).The West Phoenix drilling facility is scheduled to drill production wells on the Fenja field in production licence 586 in the Norwegian Sea.Recently, Neptune Energy and Wintershall Dea have made two hydrocarbon discoveries in northwestern Germany following the drilling of the Adorf Z15 gas well and the Ringe 6 oil well.last_img read more

Letter To The Editor: Parke Should Be The One Resigning, Not Musgrave

first_imgLetter To The Editor:  Parke Should be the One Resigning, not MusgraveBy Bryan FoxIt seems that Vanderburgh County Republican Chairman Wayne Parke has an obsession with Cheryl Musgrave.Musgrave, a Republican, was recently elected county commissioner for a second (non-consecutive) term and has been asked by Parke to resign. This comes after Musgrave’s vote to fire Burdette Park Manager Jacob Murphy and replace him with Pat Tuley, former campaign manager of fellow commissioner, Democrat Ben Shoulders.“I do not believe you are performing your County Commissioner responsibilities in the best interest of the Vanderburgh County citizens. Vanderburgh County needs people in office that unite — not a divider who has their own personal agenda, ” Parke says to Musgrave via email.In the mist of this resignation request, maybe it’s time for Parke himself to step aside.To be fair to Mr. Parke, the Republican party has seen significant gains in the county since he became chairman in 2010. Evansville Re,publican Mayor Lloyd Winnecke has been re-elected in a primarily democrat city, four of the five state representatives in the county are Republican, and the party has picked-up three seats on the city council. Also, Mrs. Musgrave should have to answer tough questions with regards to how she handled Murphy’s firing. She will definitely have to answer to the voters if she decide to run for re-election in 2020.However, Parke, by calling Musgrave a divider, is essentially the one whose dividing. The feud between Parke and Musgrave is longstanding. Parke publicly endorsed Musgraves’s opponent, Alex Schmitt, in last year’s primary. This isn’t the first time Parke has done this. During the 2014 primary, Parke publicly endorsed county commissioner candidate Marsha Abell who was running against newcomer Bruce Ungetheim. This endorsement included donating to Abell’s campaign. Abell was ultimately defeated. As a county chairman, you have to let the chips fall after the primaries before having a dog in the race. Parke has failed to do that on multiple occasions and has created unnecessary political infighting.At a county caucus in 2016, Parke was asked to respond to an Indiana delegate and Newburgh native Joshua Claybourn’s decision not to vote for candidate Donald Trump at the upcoming Republican National Convention. Parke basically said that the alternative to Trump is much worse. Since Musgrave is a fellow republican, maybe Parke should apply this same philosophy to the local races as well.Perhaps Parke forgot about Ronald Reagan’s 11th commandment which says, “Thou shalt not speak ill of any fellow Republican.” Either way, Parke should resign.FOOTNOTE: This letter was posted without opinion, bias or editing.  DISCLOSURE: Mr Fox is a part-time paid free lance writer for the CCO.  Mr. Fox is responsible for the contents of the attached Letter To The Editor.FacebookTwitterCopy LinkEmailSharelast_img read more

Trump Should Copy U.S. Military Model to Fix American Child Care Crisis

first_imgSign up for our COVID-19 newsletter to stay up-to-date on the latest coronavirus news throughout New York By Elizabeth PalleyIn his campaign, President-elect Donald Trump suggested that he understood that our nation must address the child care crisis facing working- and middle-class families. He’s right that this social problem profoundly needs to be fixed.Approximately 21 percent of children in the United States live in poverty, according to the U.S. Census Bureau. In other words, a family of three survives on $19,000 a year, and a family of four on $24,000. These families have little to no money for child care. In 2013, the average annual cost of care for families with working mothers was approximately $7,400. In some states, it can be as high as $22,000, and in many states, the cost of infant care is more than 50 percent of the median family income.There are already some federal programs designed to meet the needs of low-income families, but they have never been sufficiently funded. Head Start only provides services to approximately 40 percent of income-eligible children. Families making two times the federal poverty line—$38,000 for a family of three—are not eligible for any federal assistance.Trump has suggested that he will support funding child care through tax benefits. Heavily influenced by his daughter Ivanka Trump, this plan would allow for standard deductions for child care expenses for the average cost of care—which according to the Trump campaign would be approximately $840 for a family of four earning $70,000. It would also allow the benefit to be included as a rebate for those receiving an Earned Income Tax Credit, enabling the amount to reach up to $1,200 per year per family.This is only a slight increase over the $1,000 they are currently able to receive. Under this proposal, families earning between $19,000 and $38,000 can expect to receive lower benefits from the tax changes than higher income families, though their child care costs are comparably high. Neither benefit will do enough to offset the actual costs of child care.These credits would be improvements, but they are unlikely to enable most families to easily shoulder the high cost of child care. In addition to a refundable tax credit of up to $1,000, our tax code already provides greater benefits to higher income families, despite the fact that they must pay the same amount for child care.Employers can already support dependent care savings accounts, which lets workers contribute up to $5,000 in pre-tax income. Trump has also proposed matching the first $1,000 for low-income families using tax-exempt child care accounts. Given the poverty that many American families already face and their difficulty in meeting basic needs such as food, shelter and electricity, implementing this idea may be very challenging. They simply may not be able to save their first $1,000.Certainly, child care in the U.S. cannot be improved without ensuring that the caretakers can make a living wage. On average, child care workers earn $10.39 an hour, 40 percent below the median wage. Fifteen percent of them live below the poverty line, and 46 percent receive public benefits themselves. These providers need a raise if they’re going to make a difference in children’s lives.If we want to improve outcomes for all children, we need to do more than just talk about the importance of high-quality child care: We need to provide adequate financial support for child care and child care providers. A good model is the program designed for the US military, which provides high-quality care to approximately 200,000 children daily. The staff at these centers must meet high standards.Both the center directors and the curriculum specialists must have at least a B.A. in early childhood education or in a related field. All workers at the centers must have at least a high school diploma or a GED. The parents of the children who attend pay for the care on a sliding scale.Workers are paid on average $15 an hour including extensive benefits packages. They receive training and further opportunities for advancement. Though it costs $700 million a year, our government has decided that for the children of people in the military, this is a good investment. Why not invest in a program that benefits all American children?Expanding tax benefits for families with children is definitely a start, but our country should do more, given the dire situation. We need a unitary national child-care policy to ensure that low-income and middle-income families have access to quality care, be it at home with their parents, or with other caregivers, or in center-based care. In a nation where 21 percent of children under 18 live in poverty, and 35 percent are being raised by single working parents, Trump’s child care solutions don’t go far enough.Elizabeth Palley, a former social worker and public interest lawyer, is a Professor of Social Work at Adelphi University.last_img read more

F1’s Hamilton says slave trader’s statue should ‘stay in river’

first_imgFormula One world champion Lewis Hamilton said a slave trader’s statue that was torn down and dumped in a harbour during anti-racism protests should “stay in the river”.Hamilton, who is F1’s only black driver, was commenting after protesters in the British city of Bristol toppled the bronze statue of Edward Colston, who made his fortune in the slave trade. “If those people hadn’t taken down that statue, honouring a racist slave trader, it would never have been removed,” Hamilton wrote on Instagram.  “There’s talks of it going into a museum. That man’s statue should stay in the river just like the 20 thousand African souls who died on the journey here and thrown into the sea, with no burial or memorial.A #BLM protest in Bristol, U.K., has pulled down a statue of Edward Colston, a 17th-century slave trader, dragged it through the streets and thrown it in the river. pic.twitter.com/MxDGH05wuB— Alexander Quon (@AlexanderQuon) June 7, 2020″He stole them from their families, country and he must not be celebrated! It should be replaced with a memorial for those he sold, all those that lost their lives!!”Colston’s statue was pulled down during anti-racism protests triggered by the death of George Floyd, an unarmed black man, during his arrest last month in Minneapolis. Government officials have called the statue’s removal a criminal act. But the action won some support, including from Bristol’s mayor, against a backdrop of public pressure to re-examine representations of Britain’s colonial past.Britain’s Hamilton, a six-time world champion, has been a vocal opponent of racial injustice, previously saying he was “overcome with rage” and criticising “white-dominated” Formula One for its silence over the Floyd incident.
