That's a big table containing details and links to movies as follows:

 1. ICME Event Start- Beginning of the ICME signature in-situ at ACE

 2. ICME Event End- Estimated End of ICME signature in-situ at ACE

 3. CME in LASCO- First appearance of the CME in LASCO C2, or STEREO COR2 in the event of a LASCO data gap.

 4. ICME TYPE- Describes the signature in-situ, Shock Front (SH), MC (Magnetic Cloud), EJ (CME Ejecta Front)

 5. AR- The Source Active region of the CME, if there is one

 6. Surface Location- The location of the Active Region or, if there is no AR, the approximate location of the eruption.

 7. Flare Magnitude- If the CME is associated with a flare, the strength of the flare.

 8. Flare Onset Time- The beginning of the flare

 9. CDAW VEL C2*- The velocity of the CME, as determined by the CDAW CME Catalog

10. SEEDS VEL C2*- The velocity of the CME, as determined by the SEEDS C2 Catalog

11. SEEDS VEL A*- The velocity of the CME, as determined by the SEEDS STEREO Catalog

12. SEEDS VEL B*- The velocity of the CME, as determined by the SEEDS STEREO Catalog

13. AVG. VEL- The average velocity of the CME as calculated by determining the time of the CME in C2 and the beginning of the signature in-situ

14. Velocity- The average velocity of the ejecta at ACE

15. DST Peak/DST Peak Time- The lowest value of the DST index and the time it occurs (as long as the peak is below -40)

16. Ejecta Start Time- The beginning of the CME Ejecta in-situ (if there is no shock this is the same as the ICME start time)

17. Quality Rating- This denotes the quality of the event's signature in-situ, 1 is the best, 3 is the worst.

18. In-Situ Link- A link to the in-situ data for the event

19. C2 Link- A link to a movie of the CME in LASCO C2

20. COR2 Link- A link to a movie of the CME in STEREO COR2

21. EIT/AIA Link- A link to a movie of the eruption on the Sun as seen by either the SOHO EIT or SDO AIA instrument

Real-time Cosmic Ray Variations (Data base of Moscow Neutron Monitor)
WEB address: http://cr0.izmiran.rssi.ru/mosc/main.htm
Provider: © Cosmic Ray Department of Solar-Terrestrial Division of IZMIRAN.

Database contents of Moscow neutron monitor data starting from 1958: Hourly data up from January 1958 (IGY-monitor until September 1968, then 18NM, until 1994 24NM-Supermonitor). The interval of accumulation: hourly from 1958; besides, 5-minute data (from January 1989 - June 1991) and 1-minute since July 1994. Database updating goes in real time.

Interactive access
Data in this regime are available in graphical and in digital presentation as well.
All graphical plots are given relative to February 1987.
Time Resolutions: (1, 5, 10 or 15) minutes, hourly:(1, 6 or 12), dayly:(1 or 27), 1 month, 1 year;

  • There are three types of 1-minute data: neutron monitor data corrected for atmospheric pressure (C), atmospheric pressure (P), and neutron monitor data uncorrected for atmospheric pressure (U).
  • Hourly data are presented uncorrected (U) and corrected for atmospheric pressure (P).
  • Pressure corrected hourly data are kept as original (O) and corrected (C).
