Solar flare
| Issue | When the M class or greater LDE flare occurs (for over 30 minutes) |
| Issue | When the X class LDE flare occurs |
| Issue | When a solar flare with optical importance 3 or more (3F, 3N, 3B, 4F, 4N, 4B) occurs |
Coronal Mass Ejection（CME）
| Issue | When the FULL HALO CME (CME from the Sun Surface to all directions) is observed
* Only if the CME associated with the large-scale flare which makes alert to be issued is generated |
Geomagnetic disturbance
| Issue | When there is a report of a geomagnetic storm from Kakioka |
| Cancel | When the geomagnetic storm is terminated |
Solar Proton
| Issue | When the proton flux (≧10MeV) observed by GOES is over 10 PFU |
| Issue | When the proton flux (≧10MeV) observed by GOES is over 100 PFU |
| Issue | When the proton flux (≧10MeV) observed by GOES is over 1000 PFU |
| Issue | When the proton flux (≧10MeV) observed by GOES is over 10000 PFU |
| Cancel | When the proton flux (≧10MeV) observed by GOES returns to less than 10 PFU |
Radiation belt electron
| Issue | When the 24-hour electron fluence (≧ 2 MeV) observed by GOES is over 3.8 x 108 [/cm2 sr] |
| Issue | When the 24-hour electron fluence (≧ 2 MeV) observed by GOES is over 3.8 x 109 [/cm2 sr] |
| Issue | When the 24-hour electron fluence (≧ 2 MeV) observed by GOES returns to less than 1.9 x 109 [/cm2 sr] |
| Cancel | When the 24-hour electron fluence (≧ 2 MeV) observed by GOES returns to less than 1.9 x 108 [/cm2 sr] |
