Ian Musgrave The Full Moon was on the 4th, and the last Quarter Moon will be on the 11th with the new Moon on the 19th, so it's time for some serious imaging (unless you are a narrowband fan, that is).
Rapidly brightening comet 96P/Machholz 1 has several interesting encounters, but these are all too low for the iTelescopes to see. It will pass through the SOHO lasco C3 instruments FOV mid month.
Chart showing C/2011 L4 Panstars near Sigma Librae. The large rectangle is the field of view of iTelescope T14. The medium rectangle is the field of view of iTelescope T20. Although the comet is shown as magnitude 14, it is actually 12.6 (or brighter). Click to embiggen.
Comet C/2011 L4 PANSTARRS is in Libra and currently around magnitude 12, brightening faster than expected. On July 13 it will pass close to magnitude 11.6 galaxies NGC 5903 and NGC 5898. Between July 9 and and July 18 the comet and the galaxies will be within the FOV of T20.
Chart showing C/2011 F1 Linear. The large rectangle is the field of view of iTelescope T14, the medium rectangle the field of view of T20. Although the comet is shown as magnitude 12.2, it is actually 10.7. Click to embiggen.
Comet C/2011 F1 LINEAR is currently magnitude 10.7, brighter than predicted and may reach magnitude 9.
Between July 10 and 11 it is within T20 range of 10.8 magnitude galaxy NGC 5371, and within T14 range of NGC 5350 (11.4), NGC 5354 (11.5) and NGC 5353 (11.1). Then on July 18 the comet is close to magnitude 11.6 NGC 5395. On the 24th it will meet NGC 5444 and NGC 5533.
Comet C/2011 UF03 LINEAR has also brightened more than expected, and is now magnitude 10.9. It is slowly fading, but will still be around magnitude 12 during this month. Sadly there are no interesting encounters for this comet as it travels through Ursa Major.
Asteroid encounters are less exciting than comet encounters, but nonetheless you can get some nice animations or time lapse images.
On the 10th 8 Flora is 0.6 degrees from M61 and 6 Hebe is 0.5 degrees from NGC 3628. On the 15th 44 Nyssa is 0.2 degrees from NGC 6440. On the 21st 8 Flora is 0.5 degrees from NGC 4527. On the 24th 11 Parthenope is 0.05 degrees from NGC 7600. On the 27th 6 Hebe is 0.4 degrees from NGC 3810 and on the 28th 1 Ceres is 0.6 degrees from NGC 1647.
