OCCULTATION NOTES January to March 2009

January 07 OCCULTATION OF THE PLEIADES.
The waxing gibbous moon and the Pleiades come together early this evening for the first occultation of stars belonging to this glorious Open Cluster of bright stars in 2009. The event gives a good opportunity for astrophotographers to do some imaging, and excellent opportunities for SPA members to try timing the brighter events. There is also an interesting graze involving the m(v) 4.3 star Taygeta. The graze line stretches across mainland Britain from Egremont in Cumbria, via Carlisle to the North Sea coast at Bamburgh. Taygeta is occulted for observers south of this line. Brightest star in the group Alcyone m(v) 2.8 undergoes a grazing occultation too. The graze line for this starts near Bournemouth and heads towards the north east, passing through Southampton, west London, Epping, and reaching the North Sea coast just north of Dunwich. Alcyone is occulted for observers to the north of this line.

January 14 GRAZING OCCULTATION OF 65 LEONIS.
The graze line passes almost exactly west to east across the country with observers to the south of the line witnessing a complete occultation of the m(v) 5.6 star. The graze line clips the most northerly point of Ireland and touches the Scottish coastline at Girvan, to the south of Ayr. After crossing part of southern Scotland it leaves the country at Lynemouth in Northumberland. Just to the north of Newcastle.

February 04 OCCULTATION OF THE PLEIADES.
This morning, you have another chance to image the spectacular juxtaposition of the lovely bright components of M45, lying near to the gibbous waxing moon, low in the west-north-western sky.


If you require specific data for your locality, or details of occultations involving fainter stars, please get in touch with the Director of the Occultation Section giving your geographical location. Graphical representations of each occultation will be available at the Occultation Section's web-site before the event is due to take place. This is the UK's definitive site for lunar and asteroidal occultations.
