Observing Report 08/23/03
Equipment: Heep ('umble 4.5" DS Newtonian on EQ mount, 900mm, f/8), 16x50 bino's
Eyepeices: 20mm, 10mm, 6.7mm Meade Plossls
Location: Newmarket, Ont. (approx. 44n, 79w)
Time: 0300 - 0430 UT
=======================================================
As bad as Friday's futile attempt was, Saturday's observing session was in every respect its opposite. Set Heep on front lawn around 8:00 PM local (2400 UT). Go back inside to watch movie rental, "Head of State". For those who missed Siskel and Roeper's review, don't bother. Movie over, wife and daughter wasting the night sleeping, I venture outside. No neighbour's porch light. Limiting magnitude at leat 4.0, several stars in Little Dipper visible. Most streetlights hidden by trees on front lawn. And Mars high in the sky directly in front of me. It's 0300 UT.
Seeing was much improved over the previous evening. Mars showed a wealth of detail with 6.7mm. Very dark ring around SPC, but thinner than previous viewing (Aug. 18). Solis Lacus to the west, large grey band visible to the south running the breadth of the planet. Two darker elongated rectangular-shaped features, separated by a thin line, were visible (barely) east of Solis Lacus, separated from it by a wide swath of washed out peach colour. The planet was brighter than I have ever seen it; so much so that I bet I could use a Moon filter and still improve the image. The best views, in fact, occured when a thin, high cloud passed between myself and Mars, and the dark grey features were darker and more defined.
