The Director of the SPA Solar Section is always pleased to have solar observations and new members joining the Section. Section members observe the Sun whenever possible and record their observations in various ways . Some use specialised H-alpha filter systems which show prominencies, filaments, plaging and flares as well as some sunspots, others use telescopes to see sunspots and faculae. Some take photographs , some make drawings, some count AR's and their individual sunspots , some do all of these. The intention of the Section is to make as complete a record as possible of the solar activity during each month , from the observation material sent in by Section members. The prime work of the Section is the counting of Active Regions ( AR's ) and the number of individual sunspots in them,
The Director compiles a Monthly Report and these are published by the SPA in it's ,agazine and newsletters and are also available for viewing on the Solar part of the SPA website , where a selection of photographs and drawings received are displayed. The Director prepares an Annual Report for the SPA Council which sets out the work of the Section during the previous year and summarises the solar activity recorded . Graphs showing the changing frequency of AR's and sunspots over time are prepared each year. These have been completed for many years now.
The Director would be pleased to provide further information to prospective solar observers . If you are an SPA member please quote your membership number . Should a non- email reply be required please forward an A4 stamped addressed envelope
All observations sent must show the date , time ( in UT) , and equipment used. If a drawing or photograph the orientation ( N, S, E and W points ) should be added, plus the observer’s name and location.
ALWAYS REMEMBER ……..
THE SUN IS THE ONLY ASTRONOMICAL OBJECT THAT CAN , IF GREAT CARE IS NOT TAKEN, CAUSE SERIOUS OR PERMANENT DAMAGE TO AN EYE.
NEVER LOOK AT IT WITH YOUR NAKED EYES.
