¤••••• Subject: The colours of Jupiter in 2021 (3)

Photometric spectra of individual features and regions

Received: 21 August 2022 at 23:29 JST

 

Hi all,
Here is the last topic from my study.

 

North-South scans work wonderfully to measure the global state of the planet, but are not suited to measure individual features such as the GRS. In order to produce data about them, I have experimentated a second method, which is producing photometric spectra of some precise regions of the globe, equivalent to a spectroscopic analysis, but with only a few points.

 

Values are simply found by measuring, when they are on the central meridian, the ratio of the brightness of the feature / the brightness of the whole globe, X the geometric albedo of the planet. Beofre that, the brightness of the individual feature is recalculated to find the brightness it would present, if it had the same geometric surface as the globe. By "brightness", I understand the intensity of the feature/globe measured on the photometric, unprocessed, image through a software (IRIS).

 

This method does not only work for individual spots, but also for belts or zones providing that they present a rather homogeneous aspect throughout all the longitudes. For example, in 2021, it is possible to measure the difference in albedo/color of the two parts of the NEB.

 

Because the absolute values measured inside the CH4 band are, by nature, very small in comparison with the other bands, I have made a specific graphic.

 


 

The reason why most of the values look to be much brighter than the spectroscopic albedo from Karkoschka (grey profile), is simply because the value for the whole globe includes the light gradient from center to limb. Measuring features on the CM leads to much higher values, in general.

 


 


 


 

 

As for any analysis, this way to produce results also suffers from limits:

 

It is less relevant for belts or zones that are not homogeneous throughout all the longitudes. For that reason, there is no graph for the SEB, for example.

 

Values are not corrected for the gradient of light between the equator and the poles. This means that it is only wise to compare date inside a given domain in latitude, but we should be careful when trying to compare values taken from different domains if they do not benefit from the same angle of illumination by the Sun.

 

Some measurements have been made when features where quite away from the central meridian. A coefficient has been measured to correct the data in this respect, considering that the photometric variation of the feature when turning from limb to CM was the same as its domain of origin ; but of course, in the reality, this might not be exactly the case. This could have led to errors, but I believe that they are reasonable.

 

Finally, I have made a few attempt at measuring values from past apparitions, to compare, when features presented a widely different aspect. I present two that were quite obvious, but some of the results I have obtained in this respect were mixed. So take that with caution, of course.

 

 

I hope to see some of you at the EPSC to discuss this, and many other things :)

¤••••• Subject: The colours of Jupiter in 2021 (2) North-South scans of all bands

Received: 14 August 2022 at 20:30 JST

 

Hi all,

Here is the second part of my little study.

 

Once the global albedo of the planet has been calculated, it is possible to exploit the values in different ways. One is to retrieve the photometric profile of Jupiter from one pole to the other, relevant because of the banding pattern, and scale it against the albedo value. The best way to do this would be to measure the profile at several longitudes, in order to average the local variations that still exist. However, for a given observer from an average observing site (me...) it can be difficult to obtain enough images to do so. In order to face this problem, it is possible however, to decide that a given face of the planet can be judged as "representative" of the global state of its atmosphere (especially, having the GRS at the central meridian is to be avoided!).

 

Another way to deal with this is to retrieve the profile by "misusing" a software dedicated to spectroscopy. Such softwares can measure a wider range of longitudes and not a single line (see the figure attached). This will smooth a bit local variations.

 


The profile is calibrated by finding the value of a given detail, such as the equatorial band, or any belt/zone. I will explain how I did that in the third message.

 

Below are the figures. In 2021, the planet has experimented a very strong drop in albedo of the whole system I, with an especially dark equatorial "pseudo band". In comparison with a more "normal" whitish state, the drop in albedo in blue light represents around 3/4 points of albedo (from ~80% to ~45%) which looks quite a lot.

 


 


 


 

In the meantime, the equatorial band reached a very high albedo value in the CH4 band, around 12% (starting from an albedo of 0,06 or 6%). This is a now identified correlation between extreme darkness in UV/bright CH4 value, that points at a particularily high structure.

 

I also propose two coefficients of colors:

 

1) B minus Rc : this will measure how much light is absorbed when passing from red (a color where the albedo of the planet is more steady) to blue, the wavelength where the most profund variations of albedo are recorded. This is an index to evaluate the variations of colors of belt and zones from a period to another.

 


 

2) U divided by B: this tries to reveal special episodes of strong yellow/orange coloration. In the UV, such event will traduce themselves into a superior degree of absorption in comparison with the adjacent (and relatively close-looking) blue band. In 2021, the equatorial band, inside the EZ, shows this behavior. So would do the red spots sometimes (but this will be measured with another method).

 


 

Here is a link to my EPSC poster abstract in Granada where you will find additionnal technical infos and references.

 

On the third (and last) message, I will send results from photometric spectra of individual features.

¤••••• Subject: The colours of Jupiter in 2021 (1) Geometric albedo of the planet in various bands

Received: 11 August 2022 at 05:14 JST

 

Hi all,

I'm going to send a few messages regarding the results I have obtained for my personal research, which is the measurement of the variations of Jupiter's colours. This idea had been suggested by John Rogers during the 2018 JUNO meeting in London and I have been looking to get results from that idea since then.

 

This first message presents the method and results I have obtained when trying to calculate the geometric albedo of the planet - basically the values obtained measure how much sunlight the planet is able to reflect from the amount it receives (see the links to get more details if needed).

 

Usually those values are calculated against non-variable stars, but this method can be tough to master, especially if the planet is found at a low elevation in the sky, as this was the case for me during the last years. During the EPSC 2019, Dr Jeff Morgenthaler from the Planetary Science Institute suggested me to try to find the results from the galilean satellites, and not stars. The point is that if galilean moons are not steady sources of light as will be stars, their locations very close to the planet will eliminate many sources of errors, while their own variations can be predicted at least to a reliable amount.

 

To my own surprise, the results obtained from that idea led to quite accurate results, considering the modest ambition of this amateur work.

 

Here are a links to fully understand how I processed the method if needed:
Galilean Moons-based photometry for Jupiter (EPSC 2022 oral intervention)
The colours of Jupiter in 2021 (EPSC 2022 poster intervention)
Links to the method from my Astrosurf website:
GALILEAN PHOTOMETRY FOR U, B and V BANDS
GALILEAN PHOTOMETRY FOR R AND IR BANDS
GALILEAN PHOTOMETRY FOR JUPITER: RESULTS AND DISCUSSION

The only result that has not been correctly measured with these methods is the albedo of Jupiter in Ultraviolet. For this, I'm sending as well a corrected result from the spectroscopic observation I made in August 30th, 2021, and the Alpy600 spectrograph, which looks to be quite good at measuring the Johnson U band.

 

For 2021, the results look to correctly measure a noticeable drop of the planet's albedo in the short wavelengths, compatible with the great darkening of the whole system I observable in images.

 

On the next message, I will send results from photometric north-south scans for all the observed bands.

Hi all,

Here are some UV images of Jupiter taken through 3 different filters; the Chroma Bessel U, the Astrodon Sloan u'/UVenus, and the new Baader Sloan u'.

Although it looks subtle, I think that the fading Equatorial band that was so dark in 2021 can still be barely detected through the two u' filters, especially the Baader which is the "deepest" one.

 


 


 

Also added is a B and RGB images.

Hi all,

Here are two UV images of Saturn taken with two different filters: the Chroma Bessel U, and the Astrodon Sloan u' (which I suspect to be identical to the UVenus).

The u' filter looks to show the same pattern, but with slightly increased contrast.

Dear all,

Sending you my first Mars images for this season, obtained with my home built 52 cm Newtonian at Lindby Observatory (K60), Sweden

 

Sorry if you receive some of these images a second time; I have updated the send list to ensure all email addresses are correct.

Dear all,

I have happily made my first observations of Saturn, Jupiter and Mars for this season, submitted here to your galleries and archives.

I am using my 527 mm Newt @f/15 at Lindby Observatory with Pierro Astro ADC, ASI462MC camera, NIR block filters and CH4 filter. 

 

The planets are still low from 55 deg north and thus strongly susceptible to seeing, but altitude is steadily increasing for all three of them ;)

Hi all,

Some brief moments of fair to good seeing on the 30th allowed a better result than previously.

Oval is BA is seen at lower left. Many complex spots along the STB latitudes paints a rather chaotic picture across this region.
