Moon Phases and Orbit for February 2005 per Astronomy Magazine in EDT

2 last quarter, 7 perigee, 8 new moon, 15 first quarter, 19 apogee, 23 full moon

The Moon is at apogee (252,156 miles far) on 19 February.



The current crop of sunspots is now capable of M Class solar flares, per www.spaceweather.com . Sunspots are magnetic in origin.



Thanks to Arno's at Pinpoint and Volcano List:

Piton de Fournase volcano on Reunion Island is in a seismic crisis with severe deformations and it is expected to erupt in hours.

SPECIAL NOTE



Note the addition of categories for Myanmar and Southern Sumatra of aftershocks in the FIVE List section on North Sumatra region.



With the continuing high number of 5M aftershocks there is the possibility of more high ash eruptions. It appears Piton de Fournaise volcano in the western Indian Ocean on the island of Reunion may be next, and soon.



Comments or questions are welcome.
