Fish out those binoculars Minnesota. Theres a rare sky show in the northern sky after sunset this week. And our weather looks perfect.

NASAs Near-Earth Object Wide-field Infrared Survey Explorer discovered C/2020 F3 Neowise in March. The comets nickname Neowise comes form that acronym for that sensor.

So far, the images from NASA are stunning. NASA elaborates on what we're seeing in this image.

Processed data from the WISPR instrument on NASAs Parker Solar Probe shows greater detail in the twin tails of Comet Neowise, as seen on July 5. The lower, broader tail is the comets dust tail, while the thinner, upper tail is the comets ion tail.

The twin tails of Comet Neowise are seen more clearly in this image from the WISPR instrument, which has been processed to increase contrast and remove excess brightness from scattered sunlight, revealing more detail in the comet tails.

The lower tail, which appears broad and fuzzy, is the dust tail of Comet Neowise created when dust lifts off the surface of the comets nucleus and trails behind the comet in its orbit. Scientists hope to use WISPRs images to study the size of dust grains within the dust tail, as well as the rate at which the comet sheds dust.

The upper tail is the ion tail, which is made up of gases that have been ionized by losing electrons in the Suns intense light. These ionized gases are buffeted by the solar wind the Suns constant outflow of magnetized material creating the ion tail that extends directly away from the Sun. Parker Solar Probes images appear to show a divide in the ion tail. This could mean that Comet Neowise has two ion tails, in addition to its dust tail, though scientists would need more data and analysis to confirm this possibility.

This looks like the best week for seeing Neowise in Minnesota. Weather conditions look excellent. Most of Minnesota will see a dry air mass with dew points in the 50s through Thursday. The lack of tropical moisture in the atmosphere makes for clearer skies and better viewing optics.

Dew point forecast for 8 pm Wednesday

A few clouds linger across southeast Minnesota tonight, but the rest of Minnesota will enjoy mostly clear skies. Most of Minnesota will see clear skies Wednesday and Thursday evenings.

To improve your Neowise viewing, get away from city lights. Look NNW about an hour to 80 minutes after sunset. You should see Neowise with the naked eye. But binoculars or a telescope will greatly improve your view.

NASA experts will give viewing tips on #NASAScience Live Wednesday at 3 p.m. EDT 2 p.m. Minnesota time.

Enjoy the rare sight in the northwest evening sky this week.
