The solar map above shows the current active region numbers
and locations assigned by the National Oceanic and Atmospheric
Administration Space Weather Prediction Center. The colored circle below the
active region indicates the activity level and hazard potential of an
active region. See color coding used (below right). If flares occur in the
orange shaded area on the right side of the map, they are more likely
to be directed towards Earth. Green marks at top of disk show current position angle or P-angle. P-angle is the tilt of the solar rotation axis to left and right in the plane of the sky. This may be used for orienting view with equatorial mount solar telescope. | The farside solar map shows approximate locations of regions on the far
side of the Sun (assuming a uniform solar rotation rate). Meridian
lines show days until the region might possibly re-appear on the
Earth side view of the Sun. |
