So.. it looks like aurora could be active through the weekend… good luck photo: one of the more memorable geomagnetic experiences from the south shore of Superior… a very animated proton arc from a little over a month ago

NOAA/NWS Space Weather Prediction Center confirms that a G1 warning is in effect tonight & tomorrow that brings the chance of northern lights sightings to Michigan and an even more potentially potent G2 warning is in effect for the 24th. Click for more about the scales and definitely consider subscribing for aurora alerts!!

Northern Lights and a Proton Arc!

Milky Way, A Proton Arc, and the Northern Lights

Last night I got a couple of texts that the northern lights were out. By the time I got to the beach here in northern lower Michigan, they had died back to a soft arc on the horizon. Up on the Keweenaw however, they were pretty spectacular!

In addition to being spectacular, Eric’s photos introduced me to a new northern lights term, the mysterious proton arc or proton aurora. which NASA’s Astronomy Picture of the Day explains in this link filled post (picture is below):

What are auroras made out of? Triggered by solar activity, normal auroras are caused by collisions between fast-moving electrons and the oxygen and nitrogen in Earth’s upper atmosphere. The electrons come from the magnetosphere, the region of space controlled by Earth’s magnetic field. As the excited oxygen and nitrogen molecules return to their low energy state, they emit light, seen as the auroral glow.

Sometimes, however, auroras can be caused by collisions with heavier protons, causing a more energetic display with strong ultraviolet emission. In addition, protons can temporarily capture an electron and emit light for themselves. Such a proton aurora is seen above, recorded by the IMAGE satellite. A special feature is the bright spot near picture center, embedded in a ring of auroral emission around the north magnetic pole of planet Earth.

Most solar wind protons never reach the Earth to cause auroras because they are completely deflected away at a great distance by the Earth’s magnetic field. The bright spot in the auroral ring indicates a particularly deep crack in the Earth’s magnetic field where protons were able to flow along a temporarily connected region between the Sun and the Earth, relatively undeflected, until they impacted the Earth’s ionosphere.

Read on for lots more. The good news? It looks like the wide coronal hole that was responsible for last night’s aurora will continue to kick out the celestial jams for a couple of days, meaning this weekend offers a great chance to see the northern lights in Michigan!

While it’s virtually impossible to predict when the aurora borealis will make an appearance, it’s tied to what’s happening on the sun. NOAA’s Space Weather Prediction Center keeps tabs on what our local star is doing and is my go-to for Northern Lights forecasting. They are reporting strong geo-magnetic storms likely tonight and tomorrow so keep an eye on the skies.

Also, do yourself a favor and sign up for their Aurora Alerts!

Purple Rain: Colors of the Northern Lights

Music is music, ultimately. If it makes you feel good, cool.
~Prince

Prince was a musician who had a huge effect on my life. I went to school near Minneapolis when he was transforming music through his own work and what he did with a host of artists. I’m very sad at his passing. Down at the bottom I have one of my favorite clips of Prince.

I’ve been lucky enough to see the northern lights dozens of times but have probably only seen purple auroras three or four times. Causes of Color explains the colors of the northern lights:

The sun radiates all visible colors, which is why sunlight appears white. The spectrum of visible light associated with the aurora is much more restricted. The aurora is caused by charged particles in the solar wind colliding with atmospheric atoms and ions. The collisions cause the electrons of the atmospheric atoms to become excited. As the electrons return to their original energy levels, these atoms emit visible light of distinct wavelengths, to create the colors of the display we see.

The color of the aurora depends on the wavelength of the light emitted. This is determined by the specific atmospheric gas and its electrical state, and the energy of the particle that hits the atmospheric gas. The atmosphere consists mainly of nitrogen and oxygen, which emit the characteristic colors of their respective line spectra. Atomic oxygen is responsible for the two main colors of green (wavelength of 557.7 nm) and red (630.0 nm). Nitrogen causes blue and deep red hues.

Most of the auroral features are greenish-yellow, but sometimes the tall rays will turn red at their tops and along their lower edges. On rare occasions, sunlight will hit the top part of the auroral rays to create a faint blue color. On very rare occasions (once every 10 years or so) the aurora can be a deep blood red color from top to bottom. Pink hues may also be seen in the lower area of the aurora. In addition to producing light, the energetic auroral collisions transmit heat. The heat is dissipated by infrared radiation, or transported away by strong winds in the upper atmosphere.

Ross took this on August 10th last summer. He says “The Northern Lights over Moskey Basin in Isle Royale National Park. This is the first time in my life I have seen a bright purple aurora develop.

Eyes on the November Skies: North Taurid & Leonid Meteor Showers

Somewhere Over the Rainbow

I woke up early this morning, and after seeing 5 meteors in just ten minutes, realized that the Taurid meteors were still kicking, how about an upcoming meteor shower update courtesy EarthSky’s 2015 meteor shower page:

Late night November 12 until dawn November 13, 2015, the North Taurids

Like the South Taurids, the North Taurids meteor shower is long-lasting (October 12 – December 2) but modest, and the peak number is forecast at about 7 meteors per hour. The North and South Taurids combine, however, to provide a nice sprinkling of meteors throughout October and November. Typically, you see the maximum numbers at around midnight, when Taurus the Bull is highest in the sky. Taurid meteors tend to be slow-moving, but sometimes very bright. In 2015, the new moon comes only one day before the predicted peak, providing a dark sky for the 2015 North Taurid shower.

Late night November 17 until dawn November 18, 2015, the Leonids

Radiating from the constellation Leo the Lion, the famous Leonid meteor shower has produced some of the greatest meteor storms in history – at least one in living memory, 1966 – with rates as high as thousands of meteors per minute during a span of 15 minutes on the morning of November 17, 1966. Indeed, on that beautiful night in 1966, the meteors did, briefly, fall like rain. Some who witnessed the 1966 Leonid meteor storm said they felt as if they needed to grip the ground, so strong was the impression of Earth plowing along through space, fording the meteoroid stream. The meteors, after all, were all streaming from a single point in the sky – the radiant point – in this case in the constellation Leo the Lion.

Leonid meteor storms sometimes recur in cycles of 33 to 34 years, but the Leonids around the turn of the century – while wonderful for many observers – did not match the shower of 1966. And, in most years, the Lion whimpers rather than roars, producing a maximum of perhaps 10-15 meteors per hour on a dark night. Like many meteor showers, the Leonids ordinarily pick up steam after midnight and display the greatest meteor numbers just before dawn. In 2015, the rather wide waxing crescent moon sets in the evening and won’t interfere with this year’s Leonid meteor shower. The peak morning will probably be November 18 – but try November 17, too.

Read on for viewing tips and definitely try and take a look up at night when you can as the northern lights have also been very strong lately!

Heather writes that this image is a stitch of four 11mm frames with only minor adjustments to contrast – with no color saturation or vibrancy changes. It underscores what an incredible time for skywatching it is right now with low humidity making for extra-clear skies.

Heavenly curtain at the Phoenix Church

The Keweenaw County Historical Society page about their Phoenix Church in Houghton explains:

St. Mary’s Church was built in 1858 to serve the Catholic residents in the nearby mining community of Cliff, scene of the area’s first major copper discovery in 1844. Services continued until 1899 when the church was dismantled and reassembled in Phoenix, where it was renamed The Church of the Assumption. Masses were held until 1957, when the last service marked a century of providing spiritual guidance to mining families and their descendants.

In 1985 the Keweenaw County Historical Society took over the property and began extensive repair and restoration work. The church now appears much as it did when folks from another century knelt in prayer, a fitting memorial to one chapter of Keweenaw’s proud heritage. Although now deconsecrated, the church is still used for weddings and memorial services.
