It has been confirmed that the Queen's Official Birthday will be held on 2012 June 16th and not 2012 June 9th as stated on our Astronomical and Calendarial Data Sheet for 2012 (Astronomical Information Sheet No.96). The original date of The Queen's Official Birthday nominally falls on the second Saturday of June. However, this date is subject to confirmation and in this case has been moved to the third Saturday of June.

On November 23rd 2010, it was announced (Hansard Vol. 519, No.77, p.142) that a public holiday will occur on April 29th, 2011 on the occasion of the marriage of HRH Prince William and Ms. Catherine Middleton. These arrangements have been confirmed for England, Wales and Scotland and it is expected that they will also apply to Northern Ireland.

An update (v3.1.8) to the release version of Navpac (v3.1.6) is available as of 2010 June 15th to registered users. Please consult the NavPac page for further information.

On January 5th 2010, a statement on the Queen's Diamond Jubilee was made by the Secretary of State for Business, Innovation and Skills. It stated that the late May Bank Holiday on Monday May 28th 2012 will be moved forwards by one week to Monday June 4th 2012 and that Tuesday June 5th 2012 is to be declared a one-off bank holiday thus creating a four day break to celebrate the Queen's Diamond Jubilee. Although the announcement covers England and Wales, it is expected that these changes will also apply to Scotland and Northern Ireland.

We would like to remind potential observers that our project to observe the new crescent moon is still running. We have experienced some difficulties with the e-mail system for advising observers of the date of the next new moon recently. The problem has now been resolved and we hope you will continue to make observations of the new crescent moon. We wish to apologise to our observers for these difficulties.

HMNAO will be moving part of its infrastructure to the UK Hydrographic Office in Taunton at the beginning of December. If you wish to order data or discuss your requirements, please use the Taunton contact address and telephone numbers. E-mail should be forwarded to our new e-mail addresses automatically.
