On the nights of the 15th and 16th of February 2018, an unbelievable solar activity sparked massive auroras and coronas over Senja island in Norway. The fjords got bathed in eerie green and purple light and the colors were well visible with the naked eye.

Large supernova remnant between Taurus and Auriga. Captured with my Canon 200mm lens from my light polluted backyard. Made possible with narrowband filters and a sensitive camera (ASI1600MM-C). Thanks for looking!

NGC 4410 Galaxy Group
Copyright: Mark Hanson

This rarely photographed region of Virgo contains a vast variety of galaxies. Near the centre is a relatively serene spiral galaxy pair that is collectively known as NGC 4411. Much more striking is the connected system of interacting galaxies to the north, which are collectively catalogued as NGC 4410. Much further in the distance are a few galaxy clusters, most notably Abell 1541 near the bottom left corner. Less apparent and more pervasive are hundreds of fuzzy dots in the background, these are all distant galaxies billions of light years away!
NGC 4410 is a group of interacting galaxies connected by tidal bridges and in addition to this also exhibits tidal tails and plumes. The whole menagerie of morphological features is due to the effect of gravitational interaction between the various galaxies due to their proximity to each other. This group in total contains 12 members and is located 316 million light years away and in the future is likely to merge into a single elliptical galaxy. Interestingly, NGC 4411 is only a visual pair with the galaxy on the left being 91 million light years away while the one on the right is closer with a distance of 49 million light years. Both are members of the Virgo Cluster.

the sword and the satellites
Antes de realizar esta fotografía pensaba llamarla líneas y puntos, siendo las líneas las estrellas de la espada de orión (ϴ1 y ϴ2 son las más brillantes envueltas en un halo rojizo, y Hatsia es la más brillante de la parte inferior) y los puntos dos satélites geoestacionarios. Pero tal y como se ve, uno en la parte superior (Amazonas 4A) y otro a la altura del final del recorrido de Hatsia (Star One C3), serían más bien cometitas, o comas, porque también tienen su propio movimiento. Hay otros dos satélites en la misma traza de una estrella, cerca Star One C3, y que no aparecen en Stellarium 0.14.3, el programa utilizado ). Sí hay dos puntos en la parte central, probablemente píxeles quemados, que no aparecen en la fotografía de control, tomada 30 minutos antes.

Before making this photograph I thought of calling it lines and dots, with the lines being the stars of the orion sword (Θ1 and Θ2 are the brightest ones wrapped in a reddish halo, and Hatsia is the brightest of the bottom) and the points two geostationary satellites. But as you can see, one at the top (Amazonas 4A) and another at the other of the end of the Hatsia tour (Star One C3), would be small comets, or commas, because they also have their own movement. There are two other satellites in the same trace of a star, close Star One C3, and that do not appear in Stellarium 0.14.3, the program used). Yes there are two points in the central part, probably burned pixels, which do not appear in the control photograph, taken 30 minutes before.
