The Sun’s Chromosphere
The chromosphere is like a shell of gas around the Sun's photosphere, it is less than 1% of the diameter of the Sun, and is always moving and changing.

Both images were taken on the early morning of June 13th 2019 from Monterrey Mexico. The images were taken in near IR light of 742nm to minimize the impact of the atmospheric turbulence.
Equipment used: Celestron Evolution 8 with 1.5x Barlow, camera ZWO ASI178MM with an IR pass filter (Astronomik of 742nm), each image was made from a 1 minute video from which the 30% of the best frames were stacked with AutoStakkert!3, Sharpened with Registax and further sharpened with Photoshop.

The Longest Day

Last week I spent two days in Northern Norway in order to observe and capture the Midnight Sun the first time in my life.
Atop Storsteinen mountain 420 meters above the sea level there is a good overview towards Northern direction with the Tromsøya Island and the surrounding fjords in the foreground. Standing here 24 hours was not easy and comfortable but at last here is the result, I guess it was worth it..

Electric night by Fotis Mavroudakis, on Flickr

After almost 2 hours of shooting the most intense lightning storm I have ever seen, I managed to capture over 200 thunders and lightnings in the gulf of Kavala, Greece. The final image is a stack of 72 photos.

Here is a shot I took on 6/2/19 at 1:51 am at Isle Royale National Park. I have captured meteors before but not like this. The 2 brightest streaks look like they are emanating from Saturn and Jupiter. What are the odds of that! They are numerous fainter streaks throughout the image. An astomomer friend thought they were either bolides or Elon Musk StarLink Network. Any thoughts or ideas?

Noctulescent clouds over Paris

Yesterday night we and a very bright apparition of NLC in the sky of Paris. It's the most important one since 2009.
It confirms that this activity at low latitude is related to the activity of the sun, it appens only around the minimum of solar activity.
It also illustrate that the temperature of this layer of atmosphere decrease of 2° every 10 years because heat from the ground is more and more stopped by CO2.

Explanation:
This is a lunar curve, not a lunar analemma and I explain why
The position of the Moon has been resumed every 1,481 minutes, ie 24 hours and 41 minutes. For
get a classic analemma, it would have been
it is necessary to wait 24 hours and 51 minutes (the rhythm
of the lunar month). There is a 10 minute gap.
In this way his Moon is
always a little "in advance" and this justifies the
wider curve: the satellite in the photograph is
in fact located a little further to the left of the
typical position of the analemma. The advance, which
at the end it is about 4 hours between the first day (in
top right) and the last (bottom left), not
has effect on the lunar phase recovered, at least for this
that we can perceive from the ground (enlightenment
of the satellite does not vary significantly in this
time frame). So, except for the
first shot (the one at the top right: as
explained before, the chronological progression goes from
right to left), the placement of the Moon in the
heavenly vault is always farther from that
classic.
It is therefore a choice: the composition
it does not represent the synodic month but "only" the
lunar curve, reproducing something that exists
really but that does not have a precise definition.
For a question of correctness and clarity,
I deliberately talked about "lunar curve" e
not of "synodic curve" or "lunar analemma"
just in reference to the longer time intervals
short between shots.
It will not be a classic analemma but it is anyway e
certainly a curve of great charm!
