Hi all,
Òš
1. ANOTHER JUPITER IMPACT? Australian amateur Anthony WesleyÒšhas reported seeing a very bright flash on Jupiter lasting several seconds at 20:31 UTÒšlast evening.ÒšIt appeared near the terminator limb, at roughly the position where the SEB used to be, until its recent disappearance. ÒšAll observersÒšplease take a look and see if an impact scar(s) has appeared!
The C. M. Longitudes of his raw image (link below) are:
C.M.:ÒšÒš System 1: 300.1ÒÀÒš Òš System 2: 34.1ÒÀÒšÒš System 3: 210.6ÒÀ (N.B. The System 2 Longitude is the relevant one. This longitude will be visible on the mornings of 5 June and 7 June from Ireland.)
Here is a link to photo: http://www.iceinspace.com.au/forum/attachment.php?attachmentid=77409
See the Video on Space WeatherÒš- it's quite obvious!ÒšThe 'impact', assuming that's what it was, seems to comprise several elements in quick succession, and in close proximity, but that could just be the image breaking up due to poor seeing. See:Òšhttp://spaceweather.com/

ÒšÒšÒšÒš The event is informal and, weather permitting, is hoped to generate plenty solar observing, sketching, imaging and healthy discussion. If you have appropriate solar equipment, please feel free to bring it along - the more the better.
ÒšÒšÒš For lunch, a picnic will take place in the open area around the observatory. Tea & coffee will be provided of course - all you need to do is bring your own food. If anyone has a spare picnic table or two, it would be greatly appreciated!

If you plan to stay for dinner, please let me know so that we can give approximate numbers to the bar (you can change your mind on the day of course).
ÒšÒšÒš At 8pm, our Evening Public Lecture will be presented by Dr. David Williams of the Mullard Space Science Laboratory, University College London http://www.mssl.ucl.ac.uk/~drw/ who is flying over just for the event. As this special lecture is also open to members of the public, we need to know exact numbers of those attending the evening lecture.Òš
ÒšÒšÒš If you are interested in attending the evening lecture, we would greatly appreciate if you can please reply ASAP indicating so. All other remaining seats will be offered to the general public.
ÒšÒšÒš If you have any queries, please do not hesitate to ask.
Regards & Clear Skies,

3. IRISH ASTRONOMICAL ASSOCIATION / ULSTER ARCHAEOLOGICAL SOCIETY / EHSÒšSOLSTICE EVENT, SATURDAY 19 JUNE. The IAA + UAS,Òšin conjunction with the Environment and Heritage Service,Òšwill be holding another joint event to mark the summer solstice, with a visit to Ballynoe Stone Circle, near Downpatrick, Co Down. This is the largest and most impressive and complexÒšstone circle in Northern Ireland, and mayÒšwell have a winter solstice sunset alignment withÒšthe most prominentÒšdip in the profile of the Mourne Mountains to the SW.
Òš We will visit the stone circle at 14.00, where there will be talks about the archaeology and possible astronomical connections, and then adjourn to the nearby beach at Minerstown for a BBQ/picnic. In the case of bad weather, there are local pubs for refreshments. More details, and directions, early next week, but mark your diaries now.

4. NOCTILUCENT CLOUDS. This is the start of the season for NLCs, with the first reports of sightings from Scandinavia and N. Scotland. These beautiful, ethereal, silvery / bluish -Òšwhite clouds can be seen low in the N sky from around the start of nautical twilight, i.e. near local midnight by your watches and clocks (assuming they are set to Summer Time!). They are visible only in late twilight, after the Sun is too low to illuminate the usual lower tropospheric clouds. Indeed, if any scattered lower clouds are there, they will show up as dark, silhouetted against the NLCs. A good guide is to look for Capella, which can often be seen glinting in the midst of any NLCs. Please report any sightings to me, and the iAA website, www.irishastro.org.
