Solar corona videos
(i.e., Solar corona
videos):
- Comet Lovejoy in SOHO (1995--2022?) LASCO C3 | 0:36:
Comet Lovejoy W3
(a Kreutz sungrazer
example of a
sungrazing comet)
does a sungrazing perihelion
in 2011.
There are some
coronal mass ejections (CMEs) too.
Good for the classroom.
- Coronal Mass Ejection 2006 Nov22 | 0:07:
Observed
by the Solar and Heliospheric Observatory (SOHO (1995--2022?))
in some wavelength band.
- Amazing CME-Fireworks Observed by LASCO C3 (May 2-31, 1998) | 0:24:
Impressive, but NOT explanatory.
- SOHO (1995--2022?) LASCO C2 May 2010 Solar Images | 9:14 :
You can see
at least 3
coronal mass ejections:
the most obvious ones at about 0:40, 1:30, and 2:20.
Too long for classroom,
but you can jump to the
coronal mass ejections.
- Magnetic coronal loops of the sun | 0:07 :
Note these are coronal loops,
but they do NOT seem to extend into the
corona in this
video.
Short, spectacular, and,
false color since the
light is in the
ultraviolet
(FK-399)???.
Remember the Sun's diameter is
∼ 109 times
the Earth mean diameter = 12,756.2 km.
So those coronal loops are huge structures.
Coronal loops are similar to
solar prominences in geometric structure and
in being magnetic weather, but they are hotter and most visible in the
ultraviolet unlike
prominences which are cooler and most visible
in the visible.
Short enough for the classroom.
