Lunar Occultations November 2017 to February 2018

Limiting magnitude +6.0

Details of occultations of fainter stars for your location are available from the director on request. You can either send an e-mail or use the regular post. If you choose the latter means of communication then an SAE is required please.

 If you are successful in observing these or any other of the events listed, then please let me know via email (occultation@popastro.com) or the address in Popular Astronomy, or visit the SPA Observing Forum, and share your observation report.

NOTES ABOUT THE TABLES

KEY:

Mag Visual Magnitude.
ZC Zodiacal Catalogue number, originally much favoured by lunar occultation observers.
Ph (R)eappearance, (D)isappearance or (G)raze at (D)ark or (B)right limb of the Moon.
Alt. Altitude. The angular height of the Moon above the horizon at the time of the occultation.
Az. The angular position along the horizon measured from true north in a clockwise direction (through E. S. W back to N.)
PA Position Angle, of the event, measured in an anti-clockwise direction from the direction of the Celestial North Pole.

It is worth remembering that more lunar occultation events can be seen during this period, involving much fainter stars. However, this requires a larger aperture telescope to view them successfully. The limiting magnitude for SPA listed events is normally set at no fainter than +6.0, bringing them into the range of smaller telescope apertures in the 60mm - 70mm size. If you do have access to a medium to large aperture telescope, then you will have the capability to observe many more events, even within a single night. If you are interested in seeing a more detailed listing for your specific observing location then please contact me.
