Changing MSFC values for solar activity prediction

Orekit Python Wrapper usage
1

Hi All,

I am currently trying to get a value for the solar flux using the code below:

cswl = CssiSpaceWeatherData("SpaceWeather-All-v1.2.txt")
cswl.getDailyFlux(self.time)

I was hoping to use 95% value for MSFC. I was wondering how one can see what value is currently being used, and how to change it? I was unable to find any information online about this.

Thank you for your help,
Ben

Hi @ben.hayward,

You are using CSSI solar activity data instead of Marshall solar activity data.

What you have to do is to create a Marshall model using its constructor: MarshallSolarActivityFutureEstimation(String supportedNames, StrengthLevel strengthLevel).

For supportedNames parameter, you can use the default one: MarshallSolarActivityFutureEstimation.DEFAULT_SUPPORTED_NAMES
For the strenghLevel parameter, if you want to use 95% value, you can use StrengthLevel.STRONG.

Finally, you can try something like:

msafe = MarshallSolarActivityFutureEstimation(MarshallSolarActivityFutureEstimation.DEFAULT_SUPPORTED_NAMES,
                                              StrengthLevel.STRONG)
msafe.getDailyFlux(self.time)

Best regards,
Bryan
