I was just taking the first light of my just bought
Watec 902H ultimate on the Sun in H-alpha when (1528UT) the M1 flare
occured !
Thats pure luck !
PerlVixen Fluorite 100/900 + SM90-BF30 Coronado filter + Antares 1.6x barlow.
Processing : the 14200 frames of the 9GB AVI have
been saved as 100 segments of 142 frames with Virtualdub. Then RegiStax6
has batch processed them giving one PNG by AVI. RegiStax6 registration
of those 142 images to give the final animation. |

Fluorite 102/900 refractor, JMI electrical

BF30, 1.6x Antares barlow, ASI120MM
Rather clear sky (little coutrails)
Recordings started at 12:01:48 UT and were
stopped at 12:26:56.
Each individual 30s 16b AVI taken with Firecapture was registered with AS!2,
keeping 80%. Resulting images (not all the same size) were processed with Wx
individually.
A first manual alignment was done in RegiStax5 and save to a cropped movie.
VirtualDub was then used to crop the black stripes. RegiStax5
was used again using "align with processed" a few times. The resulting
AVI was loaded in Virtualdub to change framerate from 300 to 30. "WonderFox
Video to GIF Converter" was used to make the GIF file.

My most exciting solar
flare |
On the 2005/05/06 early afternoon, the weather got
rather nice with just few sparsed clouds. I begun watching the Sun in HAlpha
at about 12UT. I used the same equipment (Perl-Vixen Fluo 102/900
in // on LX200-12", Coronado SM/TM90, VestaPro N&B RAW, 2x Barlow) as
usually. The seeing was rather good . It was obvious tha the famous 756
sunspot was decaying and that the 758 one was very active ! I started soon
making pictures and from that time to sunset was glued to my chair ... see
the one just on the right and click on it for a larger version.
I then started making AVIs all around in order to
prepare a future mosaic (asap). The GOES
X-ray flux page with 1min resolution was in permanence visible
on a the screen of another PC next by. Well it was rather flat and
I went for a quick lunch and an hour walk... I came back at 16UT and
rushed the the monitor just to see on this GOES
graph that a C1-flare had started a few min ago ! Well to bad I thought
:( But I saw that the curve was not falling down sharply and this fact gave
me hope at least for a nice show yet and maybe a new surge. A couple of
min later, recording was on ! The seeing condition at this late hour were
far from good. You can see a little "live" movie if you click here
in a little movie going up to the limb, the motors of the mount beeing stopped
and the Sun then drifting towards West. Indeed the slope went slowly up
again at a steady rate... I was thinking : will it reach the M class ? Finally
no, it went up to C9 only ! But it was rather unusual as the up and later
down slopes were not steep. This gave a remarquable long lasting show !
You can see it all on the whole Sun (Credit GOES) with high resolution here
and also see the global orientation on their still
image if you click here. Also Thierry
Legault made a mouthwatering single image with the full size SBIG CCD at
17:05 UT, time of the maximum, click here
to see it !
On the 2 astromovies shown above and also in this
one showing the whole sequence, all the bad frames resulting from
passing clouds and resulting obscurity or very bad seeing have been removed.
Complete movies with very precise timing of each image (and all the missing
bad frames) are available.
This astromovie is dedicated to
the people who have helped improving the webcams (inventing webcam with
astronymy power, B&W CCD, RAW
mode...), to Axel Canicio for his precious AstrosnapPro
software, to Cor for his great registering software Registax3
with which export of a non jerking AVI , to the authors of VirtualDub
and Aviedit and finally to Fabrice
and all the friends who have helped me for my HAlpha setup.
Capture details : Camera at 10fps auto mode
to accept slight changing nebulosity, AstrosnapPro in 100 frames integration
mode - the secret for killing bad seeing, flux mode, LRVB monochrome, live
deconvolution 100, internal guiding correlation value 10 on rather stable
but changing dots ! , one image added to AVI every 5sec, HUFFyuv lossless
compression. |

Thanks for the help ! |

For 20050115a (sun spot 720), an X2 flare occured
much later (after 23 UT, during the night in France) as seen in this SOHO/EIT195
deep UV light image.
For 20050115b (sun spot 718), as quality is not
good for full screen in divx same movie proposed in Huffyuv v2.1.1 (much
larger file 3.6Mo but Ok for full screen viewing. See site for downloading
this famous lossless codec). This flare on sun spot 718 has also been
captured by SOHO/EIT195 in deep UV light, see it here.
It it to be noted that seeing was very poor all
day ... see a 2 image animation of 720 sun spot here
.
Also you can see the increase of activity on this GEOS X-ray flux (20040115).
20050116b
1531-1543UT (37 accumulated frames). Not as spectacular but for the record.
Small flare in 720. Also here
a raw image to show what can be still done with slight overcasts. |
