 # Artemis II Solar Eclipse
 
-The Artemis II mission launched on the 1st April 2026; this launch date allowed the crew to observe a solar eclipse on the 6th April(EDT) / 7th April (UTC) after transiting the far side of the moon.

 We on the SunPy blog {ref}`rarely miss the opportunity <2024-04-03-eclipse>` to talk [about a solar eclipse](https://github.com/sunpy/solar-eclipse/).
 So when we saw the stunning photos taken by the astronauts on Artemis II, we wanted to use SunPy to compare them to other photos of the solar corona.
-I do highly recommend watching the recording of the eclipse <a href="https://youtu.be/dS9qqzSF3mI?si=NFfli3b7f0tYoVDP&t=1683">on YouTube</a>; the reactions and descriptions of the astronauts are worth it.

 These features will allow us to determine exactly where and at what angle the camera was pointing.

+It's clear from the previous image that the image is rotated around the center of the Moon.
 We can solve for this rotation by using a peak finding algorithm to locate the planets in the image and comparing these positions to the planets coordinates extracted from JPL Horizons.
-Doing this results in a {math}`-21.2^\circ` roll angle which we can add to our Maps metadata.

 ### Fitting Lens Distortion
 
 The final correction to apply to our fitted coordinate system is the distortion of the camera lens (a Nikkor AF 135mm f/2D DC).
-This makes objects distant from the centre of the image appear even more distant than they should.
+This makes objects distant from the center of the image appear even more distant than they should.
 We can quantify exactly how much the image has been distorted through comparing the expected vs actual positions of Mars and Mercury (not Saturn as it is too close to the center of the image).
 We add this distortion to our coordinate system and our planets now appear in the correct place.
