Methane 892nm band Report (with some additions by J.Rogers)
Polar caps: Both caps look bright, the south cap is brighter and the north cap more extended than the south cap.
SSTB: Some Ovals look bright but images are of low resolution to recognize them all. Dark matter P-F of them.
STB: Oval BA is very bright. The little pink-pale spot at about CM225° creates a methane-dark S feature.
The large feature passing GRS meridian is methane-dark too.
STr.Z: Looks brighter in P. side of GRS than F.
SEB: It has same difference in brightness as the visual spectrum.A methane-bright plume is visible on the rifted region F of the GRS. Bright
region around 75deg
(CM2) on SEBn as a result of SED.
EZ: Very active zone. At about 60-75° (CM.2) on the P side of SED there is a dark projection. EB is sectored and dark from about 150°-350°
(CM2).
EZn-NEBs: A very active area with 6-7 dark projections (dark-blue in RGB) associated with bright areas on the F side. There is a very bright plume
at around 135°.The NEBs edge is largely covered with methane-bright haze, so the NEBs dark projections appear to be separate from the
methane-dark NEB.
NEB: Brown barges are methane-dark. NEBn is bright and WS/A-B and WS/Z are very bright.
NTrZ: Is constantly bright in all length.
NTB: The NTBs edge is also methane-bright but the rest is dark.
NNTB: Some light dark sectors are present.
NNTZ: LRS-1 is very bright but there are some more bright spots. LRS-2 at around 355° is associated with a bright area.
SSTB: Some Ovals look bright but images are of low resolution to recognize them all. Dark matter P-F of them.

I've tried to create another version of the period around IRTF observations.I used the best amateur IR images I found.
The 3/4 of Jupiter at 13-14-15 July (images 1-2 M.Kardasis 3 J.Rozakis)
Marvellous colours on NEB-NTB.NTBs is a nice tranquil red brown band.The new brown Equatorial Band is rising on the right.Some large NEBs outbreaks are visible.There is an interesting amorphous spot in in the mid-SEB on the left of the CMI.It is very bright in near-IR.The dark spot in the STropZ looks very lonely in a wide sea of white clouds.
Unfortunately in the times of professional IRTF observations from Hawai in Greece Jupiter was not observable.So I planned my observations 10 hours later on the same CM.Also at that time in Greece the sun had rised.In the last month I have acquired a methodology for daylight observations.So these are my first results combined with IRTF image.My result is poor cause the seeing was not good enough and RGB images are hard with sunlight. It is very interesting that all interesting outbreaks are visible like this very bright(5μm)/dark(visible-IR 0,8) and other prominent features.
Hello, I am very happy to present my complete effort of daylight observations. Since there is a very important and active period of Jupiter I made these observations to cover the obs-"void" in a very active period.I must say it was quite hard....
All Longitudes are not exact measurements but just an approach to show what I mean.
NTB
There is a very bright spot at around L2 115 in NTropZ-NTBs.There is alot of dark material around the spot and especially in the P. direction.
The region in the P.side of the spot is very turbulent with bright and dark patches.At L2 197 in the same lat there is a similar white area sorrounded by dark material.
NTB is very active and turbulent compared with March observations.
NEB
NEB is also very active with two dark patches at aroun L2 240 and 303 entering the EZ(possibly the ones spoted on March obs)
There are two darker regions on the NEB L2 150-213 and 325-15.
SEB
There is dark material in the GRS Hollow and especially on the F side.There are dark condensations on SEB F at L2 266 and 285 and P at 90 and 110.
