Format: 8 spectrogram panels in order H+ Heads A/B O+ Heads A/B He+ Heads A/B He++ Heads A/B The 28 energy steps cover the range from 15 ev/e to 33 kev/e in logritmically spaced increments. The uncorrected count rate is encoded using the color bar Comments about the plots appear below each one. Higher time resolution data from perigee intervals are included after the 24 hour plots
Cusp/boundary layer fluxes encounterd from ~00:30 to ~03:00, ~04:30 to ~06:00 and intermittently from ~17:00 to ~23L99
Cusp/boundary layer fluxes encountered intermittently from ~11:30 to 20:00 when the TIMAS High Voltage was turned off to prepare for the spring flip of the space craft.
Format: Energy time spectrograms covering the energy range 0.15 eV/e to 33 keV/e as indicated Flux (with preliminary calibration) encoded using the color bar Data averaged for 4 spins (24 seconds) Lower resolution He++ data is available for most of times it is missing in these preliminary plots The horizontal black bands at alternate energy steps are a consequence of the way data is acquired and compressed
April 9 from 01:30 to 04:30
The southern polar cap Fuxes of H+ and O+ are near the TIMAS threshold of detection
April 9 from 18:30 to 21:30
Weak fluxes of low energy H+ seen in the southern polar cap
April 10 from 12:30 to 15:30
The southern polar cap is full of low energy H+ and O+
April 11 from 06:00 to 09:00
The O+ and H+ low energy fluxes are concentrated on the day side of the southern polar cap.
