This package allows to automatically fetch and parse space indices.

The space index sets supported in this version are:

Space Index Set File Expiry period Information
Celestrak SW-All.csv 1 day F10.7, AP, KP, ISN, C9, Cp, ND, BSRN (historic and predicted).
JB2008 DTCFILE.TXT 1 day Exospheric temperature variation caused by the Dst index.
SOLFSMY.TXT 1 day Indices necessary for the JB2008 atmospheric model.

Those sets provide the following indices:

Space Index Set Index Description Unit
Celestrak F10obs Observed F10.7 (10.7-cm solar flux) 10⁻²² W / (M² ⋅ Hz)
F10obs_avg_center81 Observed F10.7 (10.7-cm solar flux) averaged over 81 days centered 10⁻²² W / (M² ⋅ Hz)
F10obs_avg_last81 Observed F10.7 (10.7-cm solar flux) averaged over 81 last days 10⁻²² W / (M² ⋅ Hz)
F10adj Adjusted F10.7 (10.7-cm solar flux) 10⁻²² W / (M² ⋅ Hz)
F10adj_avg_center81 Observed F10.7 (10.7-cm solar flux) averaged over 81 days centered 10⁻²² W / (M² ⋅ Hz)
F10adj_avg_last81 Observed F10.7 (10.7-cm solar flux) averaged over 81 last days 10⁻²² W / (M² ⋅ Hz)
Ap Ap index computed every three hours
Ap_daily Daily Ap index
Kp Kp index computed every three hours
Kp_daily Daily Kp index
Cp Daily planetary character figure
C9 Daily magnetic index on Cp basis
ISN International sunspot number
BSRN Bartels solar rotation number
ND Number of days into Bartels solar rotation cycle Days
JB2008 DTC Exospheric temperature variation caused by the Dst index K
S10 EUV index (26-34 nm) scaled to F10.7 10⁻²² W / (M² ⋅ Hz)
M10 MG2 index scaled to F10.7 10⁻²² W / (M² ⋅ Hz)
Y10 Solar X-ray & Lya index scaled to F10.7 10⁻²² W / (M² ⋅ Hz)
S81a 81-day averaged EUV index (26-34 nm) scaled to F10.7 10⁻²² W / (M² ⋅ Hz)
M81a 81-day averaged MG2 index scaled to F10.7 10⁻²² W / (M² ⋅ Hz)
Y81a 81-day averaged solar X-ray & Lya index scaled to F10.7 10⁻²² W / (M² ⋅ Hz)
