Planned channels

At time of this writing, there are channels: PmHeq , PmCh2 , CH , HCw , Hmii , Mag (Hmib), Lasco .


Beside traditional Hmii and Lasco all other image formats are unique here at heliograf.org , in case of Magnetograms there is Solar equator drawn over the image for easier orientation, other image channels are combined from multiple source channels in some original way...

There will probably be traditional single color channels, available in NRT (near-real-time) from Lmsal... (but this would require significant update of server side software and/or javascript clients...?) 

This morning there has been an interesting eruption on left limb:

Aia 193 with Lmsal colormap (has better contrast than what NASA/GSFC uses) 



Aia 171 with Lmsal colormap :

And a traditional 304 channel:



It is very noisy on SDO in recent years, because it has very low level and needs to be amplified a lot to match the original red colormap...

Maybe, probably not anytime soon, there could be Hmib171 Magnetograms combined with contours of channel 171 to show connection of surface magnetic field and the magnetic arches visible above them in Solar corona:



Among else these are useful to observe and understand, how the Solar regions evolve over next rotation of the Sun, what is a remnant field , how the active regions look, when their remnants dissipate over next few rotations of the Sun...

On this image above, there are active regions on north hemisphere in various stages, either fresh ones, recent remnants and quite old and almost calm remnants... Observe few rotations back, what has been on that place before...

The magnetic field is quite useful to understand filament walls separating positive and negative parts of the remnants of former active regions...

Most of the features of 171 channel have some connection and explanation in underlying magnetic field...

There will probably be original image of Swx widget from NOAA, but with browsing historical charts to help locating various Solar flares...

When I'll earn a larger space on web-hosting, there could also be some Meteorological channels here...

An ECMWF re-analysis (also available from historical data of NCEP re-analysis)



There are two images daily for Europe and two for America...
View onto Earth from 60°N, perspective projection, color encodes 850 hPa air temperature, arrows show wind, white contours are isobars...

Optimal to help one to understand weather patterns and mechanisms...

There could be Eumetsat AirMass channel, available in NRT (near-real-time), with some history:



There is also full-disk view from EumetSat, and from Goes East over America...
