Solar activity was very low during the past 24 hours.

Solar activity is expected to be very low for the next three days (29 Feb - 02 Mar) with just a slight chance for an isolated C-class flare.

The geomagnetic field ranged from quiet to active levels with a period of minor storm levels at some observatories during the local nighttime hours. Quiet conditions prevailed from the beginning of the period until about 07Z when a substorm interval began and continued through about 09Z. The planetary activity reached active levels but several individual stations attained minor storm levels during the disturbance. Activity promptly returned to predominantly quiet levels after the substorm and remained quiet for the rest of the period. The disturbance was preceded by about two hours of southward interplanetary magnetic field (IMF) seen at the ACE spacecraft (0510-0702Z, with maximum southward deflection of -11 nT). The IMF was otherwise predominantly northwards during the interval. ACE data also indicated a solar sector boundary crossing at about 1534Z. The greater than 10 MeV protons observed by GOES returned to background levels late on the 27th and remained there through the end of the period.

The geomagnetic field is expected to be quiet for the first two days (29 Feb - 01 Mar). A slight increase to quiet to unsettled levels is expected on the third day (02 Mar) due to a small but well positioned coronal hole.
