Venus occulted by the Sun: can a Solar Scope see it ?

Next June 6, Venus will be occulted by the Sun for almost two days, exactly four years after the transit in 2012.

And in 2024, 2032 Venus will be occulted again by the Sun. This happens far more often and last far longer than a transit in front of the Sun as Venus is much further away as it is behind the Sun.

The disappearance and reappearance of Venus occur at times (mentioned in UTC) favorable for AU (early morning).

But, can we observe it ?

NO ! Unfortunately not.

But as Venus is -3.3 ... a solar scope (Lunt, Coronado or ordinary scope equipped with a Daystar Quartz) might reveal the planet ?? The surface brightness of Venus is far less than the Sun, so forget it.

Really ? What are your opinions ? It is worth a try ?

And the history of LASCO C3 of 11 June 2008 with Venus left of the Sun:

Something about pushing fertiliser uphill with a little round stick come to mind...
The -26 mag solar image IMHO would swamp any chance of success, even with a good Ha filter.

I expect the "fertiliser limit" is somewhere between 0.5° and 1° of elongation. Outside of that the disk of Venus is observable past the Sun. In good skies and with adequate safety measures needless to say. So sadly, no observable contacts (that would be cool to see though). Planning to have a bit of a look over the next few weeks.

See here.
