There are dozens of reasons to invest in a telescope this summer

With clear skies forecast over this Ascension bank holiday weekend, conditions are perfect to enjoy the weather phenomenon that in these parts is referred to as ‘Lyse nætter’ (bright nights).

The nights provide star-gazers with a stunning view of the heavens complete with stars and planets, often with a vibrant yellow, red and orange backdrop (see video below).

Perfect conditions in May
Over the Danish summer, the sun does not go below the horizon lower than an angle of 18 degrees, which means its light invariably brightens up our nights, thus giving us the Lyse nætter.

Lyse nætter are not uncommon in Denmark due to its latitude, but although they are only visible between late April and August, it is during May that you are most likely to experience it due to the propensity of clear skies caused by the combination of the Gulf Stream and rise in temperatures.

Halos, auroras and meteors
There are three types of Lyse nætter: civil twilight/dawn; nautical twilight/dawn; and astronomical twilight/dawn (see factbox below).

And the list of phenomena on view is endless. From lunar halos, purple and gold auroras, the Northern Lights (aurora borealis), meteor showers, noctilucent clouds and solar/geomagnetic storms to an open view of the whole Milky Way galaxy, there are dozens of reasons to invest in a telescope.

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
