Venus is 45 degress East of the Sun, but care must be taken not to look towards the Sun. The occultation will occur at 53 degrees altitude. The Moon will be within one degree of Saturn on Tuesday and Regulus on Wednesday
- The Sun is blank again. Thursday is the Summer Solstice, when the Sun rises and sets at its most Northerly points of the East and West horizons respectively
- Some vivid Noctiluscent clouds occurred at the end of last week. Clear Summer nights near Solar minimum are often good for these high altitude luminous electric blue clouds
- There is one last, but low ISS pass on Monday at 22.39.06 WSW to S reaching 17 degrees. There are no bright evening Iridium flares this week
Week of 11th June- The Moon will be New at the end of next week and may just be visible in its 4% phase around 9.30pm on 16th directly below Castor and Pollux and above Mercury (which is now getting closer to the horizon after sunset and thus is harder to view)
- Next Sunday (17th) there should be a lovely line-up at sunset of Saturn, the 9% crescent Moon and Venus each 10 degrees or so from the other
- Spot 960 is breaking up and the Sun is quieter
- Whilst the Moon is 'dark' it is an excellent opportunity to view Jupiter and Vesta in the southern evening sky both just past Opposition
- The ISS continues to make passes and to good binos will look a little bigger since the shuttle Atlantis is now docked and post-mission since they are unfolding new Solar Panels. The ISS can be seen at its best: On Monday at 23.24.01 from W to E reaching 81 degrees. On Tuesday at 22.09.43 from W to E reaching 83 degrees and 23.44.41 from W to SE reaching 51 degrees. On Wednesday at 22.30.22 from W to ESE reaching 84 degrees. On Thursday at 22.51.00 from W to ESE reaching 55 degrees. On Friday at 23.11.44 from W to SSE reaching 30 degrees and Saturday at 22.17.58 from W to SE reaching 32 degrees
- There are no bright evening Iridium flares
the end ofWeek of 4th June- The Moon is waning and will be Last Quarter on Friday
- Mercury reached greatest elongation (angle from the Sun) on 2nd and will remain a good target for naked eye observation low on the NW horizon after sunset. Venus reaches greatest elongation next Saturday and both Venus and Mercury are now seen in Gemini. Venus is nicely aligned with Castor and Pollux at the start of the week and Saturn in Leo adds to the other two showing the plane of the Solar System (the Ecliptic) and the Zodiac constellations of Leo, Cancer and Gemini (with the Sun in Taurus..note not Gemini, for those who read their 'stars' in the papers)
- The Sun has a new active region (spot 960) emerging on its eastern limb
- The ISS returns this week with evening passes as follows: Tuesday at 00.09.20 WSW to E reaching 70 degrees and 22.55.27 SW to E reaching 39 degrees. Wednesday at 00.30.09 W to E reaching 86 degrees and 23.16.03 WSW to E reaching 68 degrees. Thursday 22.02.13 SW to E reaching 36 degrees and 23.36.51 W to E reaching 87 degrees. Friday 22.22.47 WSW to E reaching 65 degrees and 23.57.43 W to E reaching 84 degrees and the best on Saturday at 22.43.35 W to E reaching 89 degrees.

Week of 28th May- The Moon will be Full (Rose Moon) on Friday when it will be within a few degrees of Jupiter and Antares
- Vesta reaches opposition and brightest magnitude on Wednesday, but still needs a dark sky for the unaided eye. It will be harder to spot due to the moonlight and thus will be easiest again from June 4th. It can be found a couple of degrees higher in altitude and forming an equilateral triangle with Jupiter and Antares in the evening SE sky. It is moving roughly a quarter of a degree per night
- The Sun is totally blank again
- There are no evening ISS passes but one bright Iridium flare on Tuesday at 23.04.44, 29 degrees altitude in NNE
Week of 21st May- The Moon is waxing to First Quarter on Wednesday. It occults Saturn on Tuesday (but this is during daylight from UK) and then passes within 1 degree of Regulus (alpha Leo) on Wednesday

- There are no evening ISS passes this week and no bright evening Iridium flares
Week of 14th May- The Moon will be New on Tuesday and may be glimpsed as a thin sliver in WNW within a couple of degrees of Mercury at about 10 degrees above the horizon at 9.30pm on Thursday and very close to Venus on Saturday
- This is the month for the best viewing this year of the 77% illuminated planet Mercury. Though it will be dimming, its angle from the Sun is increasing into next month. On Thursday, the 2 day old Moon will be just North of the planet and on Friday should be half-way between Mercury and Venus (waning to about 60% illumination) in a line at 9.30pm. If the evenings are clear Mercury should be easy to spot around 10 degrees altitude, but do not scan with instruments until the Sun has set
- The Sun has a decaying spot but is nearly blank again
- Very unusually an asteroid (Vesta) brightens to naked-eye visibility and the next wekk or so over the New Moon is ideal. Vesta is a couple of degrees higher than Jupiter in the late evening sky in Ophiucus and forms a triangle with Jupiter and Antares
- There is a comet (Lovejoy) passing through Draco at the start of the week and on 14th will be found next to eta Draconis (2nd magnitude star), it is not visble to the naked eye but easy in good binoculars
- There are no evening passes on the ISS but there is one almost direct beam (- 8th magnitude) Iridium flare on Tuesday at 22.27.08, 41 degrees altitude in NE
Week of 7th May- The Moon is waning and will be Last Quarter on Thursday
- The large spot 953 continues across the Solar disc and though the umbra has split into several smaller shapes, the spot is only mildly active

The debris from Halley's comet has however already produced a -10 fireball yesterday, so if up keep a look out East. The radiant is to the South of the Square of Pegasus and red Mars will also be visible nearer the horizon.
- There are no ISS passes this week and no bright evening Iridium flares
Week of 30th April- The Moon will be Full (Flower Moon) on Wednesday and will be within 1 degree of supergiant red Antares on Friday
- The Sun at last has one very large (Neptune sized) spot number 953 which is midly active

- Before that on Thursday the Moon will pass within 1 degree of M44 the Beehive Open Cluster and on Friday within 1 degree of the brightest star in Leo (Regulus)
- A rare event will occur in the early hours of Friday: The Moon will pass in front of Saturn. From here however, none of the planet will disappear but we will see a grazing approach where Saturn (followed by Titan) will appear to roll along the southern edge of the Moon. This will occur in WSW at an altitude of 33.5 degrees. The timing is not ideal in that it is in the middle of the night and will last from 2.40 till 2.50 am
- Lunar Eclipse timings: The Moon is touched by the penumbra at 20.21 GMT at 24 degrees altitude in E and will then dim, entering the darker umbra at 21.33 at 33 degrees in ESE. Totality starts at 22.49 at 41 degrees in SE and lasts till 23.57 with mid eclipse at 23.25. The Moon will then brighten until resuming normal brightness at 02.25 on 4th. The Total eclipse phase is much longer than in a Solar eclipse primarily due to the size of the Earth's shadow

- The Sun remains quiet
- There are no evening ISS passes and no bright Iridium flares
Week of 15th January- Comet C/2006 P1 McNaught is now visible in daylight, a few degrees to East of the Sun, but it will go behind the Sun and will soon be too far South of the Celestial Equator for viewing from here. The comet is magnitude -5 and the brightest since Ikeya-Seki in 1965

- The Sun has a large but quiet spot 923
- There are no evening ISS passes this week and no bright Iridium flares
Week of 6th November- This is the week for the second in the pair of Mercury transits (the last so beutifully viewed in 2003). Sadly none of this transit will be visible from the UK (next will be in 2049 on 7th May and 2052 on November 9th). However, the transit can be seen on various websites including the SOHO site (see Links). The transit begins at 19.11 GMT and ends at 00.15 GMT on 9th. Note: The next visible transit will be the much rarer transit of Venus (seen in total in 2004) on 6th June 2012, but this will only be seen at its end for the 1st hour of daylight from 5 till 6am local time
- The Moon will wane during the week to Last Quarter next week-end. Whilst these clear and misty nights are common, look out for Lunar Halos and other rainbow effects caused by water and ice particles at high altitude

- There are no ISS evening passes this week
- There is one medium bright Iridium flare on Tuesday at 19.19.02, 54 degrees altitude in SSE
Week of 2nd October- The Moon is waxing to Full next Saturday (Harvest Moon)Though the October Moon is usually the Hunter Moon, the Full Moon nearest the Autumnal equinox (23rd September) is the Harvest Moon, this year the October Moon is closer. We are ending the Major Lunar Standstill season, with the lowest First Quarter Moon on 30th September (which barely reaches 10 degrees above the horizon). We will have to wait till 2015 for another standstill season (Minor) and till 2024 for the next Major (extremes) of Lunar altitude
- The Sun has several potentially active and growing spots after some time of inactivity
- The planet Uranus is currently easy to find being less than 0.5 degrees from 4th magnitude lambda Aquarius
- ISS passes are all before dawn this week

- There is one reasonably bright iridium flare on Wednesday at 20.19.05 at 58 degrees altitude in SE
Week of 18th September- The Moon is waning and will be New next Friday when it will Eclipse the Sun. The Moon is at Apogee (furthest from Earth) in its orbit so will only cause at best an annular eclipse but none of the eclipse will be visible from he UK
- Spot 904 is about to depart over the Sun's western limb for the second time and is still a site of active prominences.
- Next Saturday 23rd is the Autumnal Equinox. The Sun will rise due East and set due West before heading into the Southern hemisphere of the Celestial Sphere and our days will become shorter than the nights.
- There are no evening passes of the ISS this week
- For Iridium flare watchers there will be a spectacular flare on Monday 18th at 21.04.35 at 55 degrees altitude in E due to satellite Iridium 96

The Eclipse is only 18% and the umbra will have left the Moon's surface by 20.40 BST (The Moon will only be a couple of degrees above the horizon and too low for the 10 inch) with the Moon returning to normal brightness by 22.00 BST. The Moon is also at Perigee ie nearest to Earth in its non-circular orbit. This will make it the largest Moon for 2006
- The Sun has several spots again and the large spot 904 has returned after 2 weeks having rotated right round. There is a chance of some magnetic activity at the end of the week
- There are no bright ISS passes this wek and no predicted bright Iridium flares
Week of 28th August- The first week of an 8 planet Solar System since 1930
- The Moon is waxing and will be First Quarter on Tuesday
- On Sunday the ESA spaceprobe SMART-1 (the first to test Ion drive) will be crashed into the Moon at the end of its Luna surveying mission, to simulate a meteor impact. The impact site is Lacus Excellentiae a 100 mile wide crater at the tip of the 'leaping Hare's' left foot (as we look at it). For observers in the USA the site will be in the shadow given the phase of the Moon and thus the impact should be visible from small telescopes. The time of impact is 0541 UT (ie 0641 our time) sadly for us the Moon has long set
- The Sun now has a large bipolar spot (905) which is magnetically reversed, more evidence that the next Solar cycle has begun
- The ISS continues to make evening passes though these are better at the start of the week: On Monday at 21.08.54 from W to ESE reaching 79 degrees altitude. Tuesday at 21.32.19 from W to SSE reaching 48 degrees. Wednesday at 21.55.51 from W to SSW reaching 25 degrees. Thursday at 20.43.53 from W to SE reaching 48 degrees.

Week of 21st August- The Moon will be New on Thursday
- The Sun may retain some activity as sunspot 904 disappears
- Thursday 24th will see the vote by the IAU as to whether we change from a 9 Planet star (Solar) system to one of 12 (with perhaps more to follow). Friday 25th: The IAU have now voted and have agreed an 8 Planet system, so Pluto has been demoted to a Dwarf Planet with Ceres, UB 313 and potentially many more Trans Neptunian Objects. The critical definition is that a Planet must reign supreme in its neighbourhood ie 'clearing' all similar objects, Pluto fails in this respect
- Please note that contrary to articles in some areas of the press the planet Mars will not be unusually close and large on 27th, it is in fact at the far side of its orbit and close to the Sun in the sky. This is an Internet generated hoax.
- There are evening ISS passes as follows: On Monday at 21.37.29 from WSW to E reaching 64 deg. altitude, on Tuesday at 21.59.43 from W to E reaching 85 deg., on Wednesday at 20.47.00 from WSW to E reaching 62 deg. and again at 22.22.02 from W to ENE reaching 82 deg., on Thursday at 21.09.14 from W to E reaching 90 degrees (ie passing through the Zenith), on Friday at 21.31.31 from W to E reaching 83 deg. and Saturday at 21.53.48 from W to ESE reaching 80 deg. and 22.16.05 from W to SW reaching 44 deg.

Week of 14th August- The Moon is waning and will be Last Quarter on Wednesday
- The Sun has been active again and the large sunspot 904 has now broken into two. A Coronal Mass Ejection could cause Aurorae on 18th. More interestingly a small spot appeared on 31st July and has now been analysed to have shown reversed polarity, that is the magnetic poles (N and S) were reversed compared to the spots seen for the last 11 years of cycle 23. This may herald the start of cycle 24 which is predicted to be more active that anything seen in the last 50 years (peaking around 2011)
- On 24th August the IAU will vote on a new classification for planets and other Solar System objects, this is likely to confirm the planetary status of Pluto (though as a double planet with Charon) and also to elevate newly discovered 2003 UB313 and also Ceres (currently the largest Minor Planet between Mars and Jupiter) to planetary status making the Solar System a 12 planet system. The eccentric and inclined orbit objects will be called Plutons, other objects will be called Small Solar System Bodies and the term Minor Planet is to be dropped
- The ISS is back and evening passes are visible as follows: On Friday 18th at 22.05.54 from SW to SSE reaching 36 degrees altitude, on Saturday at 22.27.55 from WSW to SSE reaching 62 degrees altitude and on Sunday at 21.15.29 from SW to E reaching 35 degrees altitude.

Week of 27th March- The Moon wanes till directly between the Earth and the Sun on Wednesday morning. The Moon is also at Perigee (closest to Earth on Tuesday) so the Eclipse on Wednesday will be Total and of long duration as seen from Central Africa and Turkey. From UK it will be at best 25% partial and no dimming will be noticed. Partial Eclipses are even more dangerous to try and view and only regulated Eclipse filters with the CE mark are safe. The Moon's edge will start to head across the Sun from around 10.45am and will be blocking 25% of the disc around 11.30am
