SolO surveys

  1. The composite survey SolO 8h covers the 08-16 UT time range (1pixel/60sec) and zooms are 1 hour long (1pixel/10sec).
  2. The composite survey SolO 24h covers the 00-24 UT time range (1pixel/180sec) and zooms are 3 hours long (1pixel/22.5sec).

It is composed of

  1. EPD : the time histories of protons and electrons (A).
  2. a spectrum (B)
  3. NRH : a display of brightness distribution projected onto the heliocentric East/West or North/South direction versus time at 150 MHz (C)
  4. STIX : the count time histories (D)

EPD : The time histories of protons and electrons (A)

the time histories of protons (energy ranges 7.075-28.33 MeV, 47.05-104.8 MeV) and electrons (energy ranges 53-73 and 282-397 keV), drawn from low-latency data.

Multi-instrument spectrum (B)

Frequency range 600 MHz-20 kHz. Logarithmic scale.
Combines data obtained with :

InstrumentFminFmaxTime resolution
Waves RAD1 20 KHz 1 MHz 1 min
Waves RAD2 1.04 MHz 13.8 MHz 16 sec
NDA 20 MHz 70 MHz 1 sec
ORFEES 144 MHz 1000 MHz 1 sec

NRH : EW and NS brightness distribution versus time at 150 MHz (C)

  • Integration time : 10s (1 point/ 60s)
  • Each frame contains a display of brightness distribution projected onto the heliocentric East/West or North/South direction versus time ; the units of the vertical axis are solar radius.

STIX : The count time histories (D)

the count time histories in 20s time intervals in three photon energy channels (4-10, 10-15, 15-25 keV).
