That's still big (typical comet nuclei measure 1 to 3 km), but not a record setter. Hubble Space Telescope observations have since downsized it to 18 km. At first, it appeared to be one of the biggest comets in modern history, with a nucleus as much as 160 km wide. "The comet was about 9th magnitude."Ĭomet K2 caused a sensation when it was discovered in 2017. "This is a 22-minute exposure with my 16-inch telescope," says Jaeger. Austrian astrophotographer Michael Jaeger photographed "Comet K2" entering the inner solar system on June 25th: Once these are calibrated, it is possible to correct SDO data for instrumental effects and sharpen images of the sun even more than before.ĬOMET K2 ENTERS THE INNER SOLAR SYSTEM: For the past 3 million years, Comet C/2017 K2 (PanSTARRS) has been falling toward the sun-a long, slow journey from the Oort cloud. They reveal how light diffracts around SDO's optics and filter support grids. High-resolution images like these can help the SDO science team better understand the telescope. Note the bumps and irregularities in this close-up image of the Moon's limb:
NASA's Solar Dynamics Observatory recorded the 35-minute event:Īt the peak of the eclipse, the Moon covered 67% of the sun, and lunar mountains were backlit by solar fire.

The debris failed to leave the sun's atmosphere no CME was observed after the explosion. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.įAILURE TO LAUNCH: Yesterday, June 28th, a dark filament of magnetism erupted in the sun's northern hemisphere: movie.

One of the most advanced and versatile note-taking tools available for OSX that makes it easy to keep your life organised.None of these sunspots poses a threat for strong solar flares. With customisable hotkeys that can be used from outside the main application, SOHO Notes is available whenever you need it to jot down an idea. SOHO Notes can be used in conjunction with NoteLife for iPhone and iPad which enables you to synchronise your notes between devices in both directions. Notes can include tables, lists, check boxes links and much more, making it an incredibly versatile tool unlike any other note taking app. Large numbers of notes can be organised into as many different databases as you need, and within a database, sub-folders, tags and labels can be used to allow for easy searching.Ĭontacts and tasks can be attached to notes to establish a relationship, and you can also link related notes to each other. You can use your Mac's built in camera to capture photos and videos, trimming as necessary, before saving them as notes or emailing them to friends. SOHO Notes is an advanced digital note-taking tool that can be used to store and organise voice recordings, videos, text files, web files and much more in an easily navigable interface. Whether you use notes to organise work projects, household essentials or just to keep track of ideas, they can quickly become a disorganised mess that prove to be of little use.
